NEL Contents 3 Code Breakers Key Reading Strategy: Monitoring for Meaning The lesson plans in this issue of High Wire Magazine highlight the reading strategy of Monitoring for Meaning. Opportunities to practice this strategy are indicated by the symbol . For more information on this strategy, see page 10. Assessment Master 11 in the Program and Assessment Guide can be used for this strategy. Curriculum Links: social studies, technology Introducing the Magazine Setting the Scene Tell the students that, by the time they have finished reading this issue of High Wire Magazine, they will be experts in the art of developing and breaking codes. To help set the scene for the magazine’s theme, ask questions such as the following: ➣ When you hear the words “code breaker,” what comes into your mind? ➣ When might you use a code? ➣ Why do people need codes? Record the students’ ideas on a chart or have them record the ideas themselves. Making Connections Explain that this magazine looks at different kinds of codes. Ask: ➣ What famous codes do you know about? Can you tell us about them? Have the students brainstorm a list of words and ideas about codes. Encourage them to generate as many questions as possible. 4 High Wire Magazine – Volume 9, Issue 9: Code Breakers NEL Lesson Focus Visualizing Monitoring for meaning Cryptic Messages page 2 Before Reading About This Selection Anticipation Guide Featuring the Enigma code of World War II, this article discusses the use of codes in history and describes the important role of codes in technology today. Hand out copies of BLM 1, Anticipation Guide, which contains general statements about the article. Read each statement aloud as the students follow along. Ask the students to rate how strongly they agree or disagree with each statement. Then lead a whole-class discussion, encouraging them to share their views. K-W-L Chart Word Talk Glossary words: boobytrapped, cipher machine, distorted, rotors, hoax, constellations, Allied, astrologers, enciphering, decipher Other vocabulary: super brains, fanatics, concealed, intercept Introduce a K-W-L chart using the following steps: 1. Discuss codes. 2. Brainstorm what the students already know about the topic, and record this in the first column, “What I Know.” 3. Ask the students to formulate questions that address gaps in their knowledge. Record these questions in the second column, “What I Want to Know.” During Reading Anticipation Guide An Anticipation Guide contains several statements that relate to the text topic or theme. Students use the guide to prompt their thinking before they read a text. Assessment Tip Look for the students who employ a variety of strategies, such as rereading, using text features or visuals, or changing their reading rate, to clarify the meaning of the text. Extra Help Record on a chart the words the students have identified as difficult so you can refer to them after reading. NEL Visualizing Have the students close their eyes while you read aloud page 2. Ask them to turn to a partner and describe the mental images they had. Ask questions such as the following: ➣ Can you sketch your mental image? ➣ What happens to your body when you are scared, stressed, or excited? ➣ What emotions might David Balme have been feeling? ➣ Which part of the text was particularly powerful? Why? Monitoring for Meaning Have the students skim the text to look for words, phrases, or ideas that they would like to clarify. Remind them that the meanings of words in bold type are in the glossary. Clarify any points of confusion before reading on. Using a Guided Reading approach, take the students through the article section by section. Ask questions such as the following: ➣ Why do you think the article is broken into sections? How does this help us to understand the text? ➣ Why hasn’t the information in the blue boxes been incorporated into the main body of the text? ➣ What do the photographs tell you about the development of various codes? ➣ What does the word “sensitive” mean? What does it mean when applied to information? ➣ Which form of code writing do you think would be more difficult to break: steganography or cryptography? Why do you think that? Code Breakers: Cryptic Messages 5 ➣ Why was the German cipher machine called the Enigma? Can you think of other names for the machine? ➣ Why do you think some people have suggested the Voynich Manuscript is a hoax? ➣ What was special about the people who were employed to break the Enigma code? Why were they chosen for the job? ➣ Why did they wait for thirty years after the war to reveal their success? ➣ What is “criminal encryption”? ➣ Now that you have read the article, can you list the pros and cons of cryptic messages? After Reading To encourage a conversation about the article, ask: ➣ What was the most interesting part of this article? What surprised you the most? Why? K-W-L Chart Fill in the third column of the K-W-L chart. Ask the students to review the first two columns and use check marks to identify: • the information in the first column that was confirmed by the reading; • 6 the questions in the second column that were answered by the reading. Silent Exchange Silent Exchange Students write an open-ended question. The questions are passed around the group, with each student writing a response to each question. At the end, they discuss the responses. Have the students use a Silent Exchange to share their points of view about the text. Anticipation Guide Refer to the Anticipation Guide and have the students complete the column “Response after Reading.” Discuss any changes in opinion. High Wire Magazine – Volume 9, Issue 9: Code Breakers NEL Graphic Organizer page 8 Featured Graphic Organizer: Mind Map A mind map is a simple way of organizing information. It centers on one topic and branches out to include increasingly specific pieces of information. The ideas can then be used in various forms of writing, such as book reports or essays. It is especially useful when studying or reviewing because it helps students to remember key points. Using different colors for different levels or kinds of information is helpful for visual learners. Reading and Discussing the Page Read aloud the introductory passage. Ask the students to skim the mind map, then guide them through it step by step. Draw their attention to the various components: • The topic (codes) is in the middle of the web in a bright color with a white background. • The branches lead to the subtitles (four different kinds of information about codes), changing to the color in which the information is presented. • Each subtitle has at least two branches. Each branch leads to a distinct piece of information in the same color as the subtitle. Ask questions such as the following: ➣ Why is a mind map useful? ➣ How has the information been organized? (Record the students’ responses on the board.) ➣ How do you read this mind map? How do you know where to start? ➣ How do you know where to go next? Is it obvious? Does it matter? ➣ Where can you add new branches to the map? What information would you add? Discuss the students’ questions, then ask questions such as the following: ➣ How can a mind map help to clarify your ideas and organize your writing? ➣ What questions do you have about how to make a mind map? Make sure that the students understand exactly how the organizer works. Have them apply their understanding to “Wordplay” on BLM 2, Mind Map. NEL Code Breakers: Graphic Organizer 7 Lesson Focus Making connections Making inferences Monitoring for meaning Wordplay page 10 Before Reading About This Selection Making Connections This story follows three friends as they attempt to decipher a series of mysterious messages and the meaning of an ominous motorcyclist. The friends soon realize that nothing is exactly as it seems. Discuss the title of the story. Ask questions such as the following: ➣ What springs to mind when you hear the title? ➣ What else could “wordplay” mean? ➣ Have you ever heard the expression “a play on words”? What does it mean? ➣ Look up “wordplay” in a dictionary. Does it mean what you thought it did? Word Talk Probable Passage Vocabulary: leather-clad, online catalog, fluorescent, abbreviation, monetary Hand out copies of BLM 3, Probable Passage, which contains a brief summary of the text and includes key words and phrases. The students can then compare this passage with the story. Probable Passage The teacher lists key words from the selection and the students discuss them. They may be asked to arrange the words into categories. The students then use the words to fill in the blanks of a Probable Passage (one that might occur in the text) or to write their own Probable Passage. Say Something Students work in pairs, taking turns to read sections of text aloud. The reader pauses occasionally to say something about the text, for example, a prediction, question, comment, or connection. During Reading Making Inferences Read aloud the opening paragraphs, modeling the Think Aloud approach. Have the students take turns reading pages 11 to 13 with a partner, sharing their responses using Say Something. To guide their thinking, ask questions such as the following: ➣ Is the Harley Davidson rider important? Why/why not? ➣ What does “five in the key” mean? ➣ Why would someone exaggerate when they were losing? ➣ Do you think the characters are right to assume that the motorcyclist is up to no good? Why do you think that? ➣ What do the numbers beside the clues mean? ➣ What does it mean when people roll their eyes? Why did Rae do it? Stop at this point to find out if there are any words, ideas, or phrases that the students are confused about. Discuss these and review strategies that the students can use to help their comprehension. Tracking the Clues Explain to the students that it can be difficult to follow the story as well as keep track of the clues. Return to the story, and together, produce a Chain of Events that summarizes the clues. Reflection and Metacognition Discuss the questions that required the students to make inferences. Was this difficult? If so, why? 8 High Wire Magazine – Volume 9, Issue 9: Code Breakers NEL Double/Triple Entry Journal Two- or three-column charts are used for students to record parts of the text and their inferential or critical thinking about each part. Teaching Tip To monitor the students’ understanding of the selection, ask for volunteers to give an oral summary of the text. Assessment Tip Look for the students who employ a variety of strategies, such as rereading, making use of text features or visuals, or changing their reading rate, to further clarify the meaning of the text. Somebody Wanted But So Students choose a character from the text and create a sentence saying what the character wanted, what stands in the character’s way, and how the conflict is resolved. Monitoring for Meaning Have the students read pages 14 and 15 independently. Ask them to draw up a Double Entry Journal with the headings “Words from the Text” and “My Questions.” Have them write questions about the text as they read. The questions may apply to points of confusion or inferences they make. For example, they may want to know more about the cryptic clues. When the students have finished reading, have them discuss answers to their questions in groups of four or five. Read Aloud Read aloud the rest of the story. This gives the students an opportunity to benefit from the fluency of a good reader. Discuss the outcome of the story, asking questions such as the following: ➣ Did the story end in the way you expected? ➣ Did you enjoy this story? Why/why not? ➣ Why was Johnny’s grandmother dressed as a biker? What was her intention? After Reading Somebody Wanted But So Have the students complete a Somebody Wanted But So activity to show each character’s points of view. Making Connections Discuss the students’ responses to the story. Ask questions such as the following: ➣ What emotions would each of the characters have experienced? ➣ How would these emotions change at different points of the story? For example, when the characters saw the motorbike, found clues, visited Grandma, thought Grandma was in trouble, and realized it was a trick. ➣ Would you feel the same? ➣ Would you see a biker as a sinister character? ➣ What does the story tell us about stereotyping and making assumptions? ➣ How would you feel if your grandmother played a trick like this? Aesthetic/Creative Response The students could write a story imitating the author’s use of clues. You may wish to suggest one or two scenarios. NEL Code Breakers: Wordplay 9 Strategy Focus page 18 Key Reading Strategy: Monitoring for Meaning Monitoring for Meaning is one of the most important strategies we use when learning to read. As readers, students need to be able to realize when they have lost the meaning and use fix-up strategies to get back on track. Students can use a number of strategies when decoding a text. These include rereading, reading on, using photographs or illustrations in the text, and taking notes. Reading and Discussing the Page Have the students turn to page 18 and follow along as you read aloud the title and first paragraph. Explain that Monitoring for Meaning means checking that you understand what you are reading. The blue section on page 18 suggests strategies that students can use to check their understanding. Read aloud Try It Out on page 19, and have the students apply these strategies to “Wordplay.” Remind them that they must monitor their understanding as they read. Have the students complete BLM 4, Monitoring for Meaning, to practice this strategy. As a class, find the answer to the question, “What do you get when you cut a rock in half?” Using a process of elimination, model how to find the correct answer in the list of possible statements (“Two stones”). This activity presents a two-fold challenge in that the students must monitor their understanding of the activity as well as their understanding of the clues in the story. Encourage the students to refer back to the story to clarify the clues and answer the questions. Before moving on to “The Human Code,” use “Wordplay” to model some other reading strategies such as taking notes, asking questions, and rereading. Demonstrate how you can choose a particular strategy to help you to make sense of any confusion. For example, you could say, “I felt confused when Johnny figured out the answer to the question, ‘What do you get when you cut a rock in half?’ I decided to reread the story and look for references to ‘stonewall’ to help me understand the clue.” After reading, ask questions such as the following: ➣ What strategies did you use? ➣ Have you used [strategy] before? ➣ Why did you use [strategy]? ➣ Are there other strategies you could have used? Have the students read pages 20 and 21 independently. Ask them to mark the places where they have trouble gaining the meaning so that they can go back later. Remind them to take their time when solving a problem. 10 High Wire Magazine – Volume 9, Issue 9: Code Breakers NEL Encourage them to: • choose a strategy that they think will help; • try it; • move on if the strategy works; • try another strategy until they are successful. Have the students repeat the process with each page. When they have resolved their trouble spots, have them reread the selection and retell what they have read to a partner. NEL Code Breakers: Strategy Focus 11 Lesson Focus Making predictions Monitoring for meaning Asking questions The Human Code page 20 Before Reading About This Selection Word Splash This article describes the race to map the human genome and why this achievement was a major scientific breakthrough. Using a Word Splash, write some words from the article onto chart paper or a transparency for the students to use when predicting the content. These words could include “genome,” “chemical,” “identical,” “strands,” “genetic,” and “decipher.” New Vocabulary Word Talk Glossary words: genome, daunting, patent Other vocabulary: DNA, genes, molecule, genetic, glitches Word Splash Key words from the text are “splashed” or written onto an overhead transparency or chart paper. Students use the words to predict the content of the text. Extra Help Rereading this text may benefit those who are struggling with the scientific concepts in the text. Reflection and Metacognition Have the students reflect on which strategies they found most helpful for extracting meaning from the text. There are a number of methods of introducing new vocabulary. For this article, use the following method: 1. Introduce a new word and explain its meaning. 2. Have the students write a meaningful explanation and create a visual. During Reading Monitoring for Meaning Read aloud the text as the students follow along. Have them use sticky notes to mark places that pose problems with comprehension. They can then work in small groups using some of the strategies you have discussed to help them extract meaning and clarify one another’s points of confusion. If all group members are confused by one point, suggest they put it to one side and move on. When all groups are finished, discuss the problems as a class and work together to clarify the trouble spots. Graphic Organizer Have the students revisit the mind map on pages 8 and 9 and prepare a similar map for “The Human Code.” This will indicate how well they have understood the text and highlight any remaining points that need to be clarified. After Reading Silent Exchange Have the students use a Silent Exchange to share their points of view about the text. Asking Questions Have the students work in groups to formulate questions about the theme of the article. They can then use library or the Internet to research the answers. 12 High Wire Magazine – Volume 9, Issue 9: Code Breakers NEL Lesson Focus Making connections Text features Making inferences Navajo Code Talkers page 24 Before Reading Anticipation Guide About This Selection Navajo code talkers have only recently been acknowledged for their role in World War II. Using a highly complex code, they protected secret military information from the enemy. Word Talk Glossary words: reservation, tactical, imposter, declassified Other vocabulary: tones, impenetrable, consequences, genuine, Congressional, civilians, Cheyenne Hand out copies of BLM 5, Anticipation Guide, which has general statements about the article. Read aloud each statement as the students follow along. Ask the students to rate how strongly they agree or disagree with each statement. Then lead a whole-class discussion, encouraging the students to share their views. Making Connections Discuss what the students already know about code talking from other articles in the magazine as well as their own prior knowledge. There may be students in the class who know about Navajo code talking. Ask questions such as the following: ➣ What have you learned about codes and code talking? ➣ Have you ever heard of Navajo code talking? What do you know about it? ➣ Have you ever used a code of your own? Can you think of codes we use in our everyday lives? During Reading Text Features Reflection and Metacognition Ask the students to discuss how the illustrations and photographs helped them to understand the story. Assessment Tip Look for the students who employ a variety of strategies, such as rereading, making use of text features or visuals, or changing their reading rate, to further clarify the meaning of the text. NEL Have the students look over pages 24 to 29 to note the features of the text (headings, subheadings, photographs, captions, fact boxes, glossary words). Have them follow along as you read aloud page 25. Ask questions such as the following: ➣ Why has the designer used a khaki color for the headings? Is it effective? Why/why not? ➣ What additional information do the photographs and fact boxes give you that the text doesn’t? ➣ Why hasn’t this information been included in the main body of the text? ➣ What do photographs offer that illustrations and other graphics can’t? Double Entry Journal Have the students read the rest of the article independently. Ask them to use a Double Entry Journal with the headings “Words from the Text” and “This is Important/Interesting Because.” They can use this to note important or interesting facts. Code Breakers: Navajo Code Talkers 13 After Reading Making Inferences Prompt a discussion by asking questions such as the following: ➣ What was the most important part of the article? Why do you think that? What was the most interesting? ➣ How might the code talkers have felt when they received their Congressional Gold Medals? ➣ Why did the code talker Sam Billison say, “We are happy, but we are also sad”? Encourage the students to go back to the article and reread to find the answers. Anticipation Guide Go back to the Anticipation Guide the students filled in before reading. Have them fill in the column “Response after Reading,” and discuss any changes in opinion. Write a Message Using the Navajo code alphabet, the students could write a message about an interesting fact from the article. They could copy their messages onto cards, writing the answer on the back, to make a class set of facts. 14 High Wire Magazine – Volume 9, Issue 9: Code Breakers NEL Lesson Focus Making connections Monitoring for meaning Asking questions About This Selection On this web page, the Codemaster explains how a code called the One Time Pad works. Ask an Expert: Making and Breaking page 30 Before Reading Making Connections Tell the students that they are going to read a selection called “Making and Breaking.” Ask questions such as the following: ➣ What do you think the selection will be about? ➣ What might we make and break? Explain that a character is asking the Codemaster for some ideas for new codes she and her friends can use. Ask: ➣ What might a One Time Pad be? ➣ Does the theme of the magazine help you to predict what it might be? ➣ Do the illustrations help you to predict what it might be? During Reading Monitoring for Meaning Assessment Tip Look for the students who employ a variety of strategies, such as rereading, making use of text features or visuals, or changing their reading rate, to further clarify the meaning of the text. Review strategies the students can use to help them have a deeper understanding of the text. Ask them to read page 30 independently, then ask questions such as the following: ➣ Did this part of the text make sense to you? ➣ What strategies did you use to help you out? ➣ Is there anything that still needs to be clarified? Have the students read the rest of the text, then ask questions such as the following: ➣ Do you think a One Time Pad is a code you could use successfully? Why/why not? ➣ How do you rate this code in terms of “unbreakability”? After Reading Asking Questions Ask questions such as the following: ➣ Do you have any unanswered questions about the text? ➣ How could you find the answers? ➣ Was the text easy to understand? Can you think of other ways to present the information? ➣ What other thoughts or observations do you have about the text? NEL Code Breakers: Ask an Expert 15 Project page 32 Featured Project: Develop Your Own Code Materials required: writing materials Tell the students that they are going to be inventing their own code. Read aloud the introduction and the instructions in the orange boxes. Have the class brainstorm a list of codes they have read about. These could include: • the Enigma • the Voynich Manuscript • online encryption • security codes on the Internet • the One Time Pad • the human genome. Write these on the board or on a piece of chart paper. Ask the students what the main elements of each code are and list these as well. For example, the main elements of the Navajo code would include: • whole words used to represent single letters • more than one word representing a single letter • names of birds representing airplanes; names of fish representing ships. This will be useful in helping the students to decide on the form of their code. Have the students work through the task independently. 16 High Wire Magazine – Volume 9, Issue 9: Code Breakers NEL Blackline Master 1 Anticipation Guide Name: ______________________________ Date: __________________________ What to do: Before reading “Cryptic Messages” (Code Breakers, pages 2–7), read the statements in the table below.

Code Breakers: Strategy Focus 21 Blackline Master 5 Anticipation Guide Name: _______________________________ Date: __________________________ What to do: Before reading “Navajo Code Talkers” (Code Breakers, pages 24–29), read the statements in the table below. In the first column, write your response: strongly agree, agree, disagree, or strongly disagree. Read the article, then look back at the statements. Have you changed your ideas? Write your new response, or rewrite your original response, in the final column. Response before Reading Statements Very few people outside the Navajo tribe speak the Navajo language. Codes are only as safe as the code books they are recorded in. Movies should not be made about historical events because they can never tell the full story. Using an alphabet as a code will not make the code difficult to break. Using a language as a code opens it up to all speakers of that language. 22 Code Breakers: Navajo Code Talkers Response after Reading
