(For your convenience, please find linked the TEA Commissioner’s List of State Board of Education Approved Instructional Resources and Midcycle State Adopted Instructional Materials.) Lesson Synopsis: Students count mixed collections of coins using compound skip counts to name the sum, determine equivalent collection, and record the value using the cent or dollar symbol in real life problem situations. TEKS: The Texas Essential Knowledge and Skills (TEKS) listed below are the standards adopted by the State Board of Education, which are required by Texas law. Any standard that has a strike-through (e.g. sample phrase) indicates that portion of the standard is taught in a previous or subsequent unit. The TEKS are available on the Texas Education Agency website at http://www.tea.state.tx.us/index2.aspx?id=6148 2.3 Number, operation, and quantitative reasoning. The student adds and subtracts whole numbers to solve problems. The student is expected to: 2.3D Determine the value of a collection of coins up to one dollar. 2.3E Describe how the cent symbol, dollar symbol, and the decimal point are used to name the value of a collection of coins. Underlying Processes and Mathematical Tools TEKS: 2.12 Underlying processes and mathematical tools. The student applies Grade 2 mathematics to solve problems connected to everyday experiences and activities in and outside of school. The student is expected to: 2.12A Identify the mathematics in everyday situations. page 1 of 31 Enhanced Instructional Transition Guide Grade 2/Mathematics Unit 07: Suggested Duration: 5 days 2.12D Use tools such as real objects, manipulatives, and technology to solve problems. 2.13 Underlying processes and mathematical tools. The student communicates about Grade 2 mathematics using informal language. The student is expected to: 2.13B Relate informal language to mathematical language and symbols. Performance Indicator(s): page 2 of 31 Enhanced Instructional Transition Guide Grade 2/Mathematics Unit 07: Suggested Duration: 5 days Grade 02 Mathematics Unit 07 PI 01 Count a collection of coins from a real-life situation such as the following: Chia emptied the following coins from her purse. Record the value of Chia’s collection using two different representations. Describe how the symbol of each representation is used to name the value of Chia’s coin collection. Compare the collection below to the above collection. Explain in words if the collections represent the same value. Standard(s): 2.3D , 2.3E , 2.12A , 2.12D , 2.13B ELPS ELPS.c.3H , ELPS.c.3J , ELPS.c.5G Key Understanding(s): Different coins can represent the same value. Each coin represents a certain value and has specific attributes. page 3 of 31 Enhanced Instructional Transition Guide Grade 2/Mathematics Unit 07: Suggested Duration: 5 days Symbols are used to record the value of coins. A collection of coins can be calculated by using repeated addition of equally valued coins. A collection of coins can be counted using skip counting. Number patterns and relationships help us determine the value of a collection of coins. Coins are used in exchange for everyday wants and needs. Misconception(s): Some students may place a cent symbol (¢) following a dollar symbol and decimal point (e.g., $0.75¢) and do not understand that this is an incorrect representation. Underdeveloped Concept(s): Some students may not realize that equivalent coin values can be recorded using different symbolic representations (e.g., 75¢ or $ 0.75). Vocabulary of Instruction: cent cent symbol “¢” coin decimal dollar dollar symbol “$” skip count Materials List: Bag of Coins (14 pennies, 40 nickels, 20 dimes, 8 quarters, 4 half-dollars) (1 collection per student, 1 collection per teacher) (previously created) cardstock (1 sheet per 2 students) cardstock (1 sheet per 4 students) cardstock (1 sheet per teacher) page 4 of 31 Enhanced Instructional Transition Guide Grade 2/Mathematics Unit 07: Suggested Duration: 5 days cup (1 per 2 students) paper (1 sheet per student) plastic zip bag (sandwich sized) (1 per 2 students) plastic zip bag (sandwich sized) (1 per teacher) plate (paper) (1 per 2 students) scissors (1 per teacher) Attachments: All attachments associated with this lesson are referenced in the body of the lesson.

Through whole group instruction, students chorally count a selected collection of coins in order to name the sum of the collection and record the value using the cent symbol. Instructional Procedures: page 7 of 31 Enhanced Instructional Transition Guide Suggested Day Suggested Instructional Procedures Grade 2/Mathematics Unit 07: Suggested Duration: 5 days Notes for Teacher 1. Distribute a Bag of Coins to each student. Instruct students to place 1 penny and 2 nickels in front of them. Display the same coins for the class to see. Ask: What is the value of this penny? (1 cent) What is the symbol you can use to write "cent"? (¢) How can you record the value of a penny? (1¢) What is the value of this nickel? (5 cents) How can you record the value of a nickel? (5¢) 2. Instruct students to place their coins in order from greatest value to the least value. Demonstrate this process for the class using the displayed coins. Allow students to make self-corrections, as needed. 3. Explain to students that since a nickel is worth 5 cents, 2 nickels together makes 10 cents. When a penny is added, the sum of the coins is 11 cents. Instruct students to count the coins again with you as they touch each corresponding coin: "5, 10, 11." Next to the coins, record: 5 + 5 + 1 = 11¢. 4. Explain to students that when people count a collection of coins that are not all the same, they often group the like coins together to make skip counting, and finding the sum, easier. The coins are often counted in sets from the largest valued coin to the smallest valued coin. 5. Instruct students to place a new set of coins in front of them; 2 dimes and 1 nickel. Display the same coins for the class to see. Ask: page 8 of 31 Enhanced Instructional Transition Guide Suggested Day Suggested Instructional Procedures Grade 2/Mathematics Unit 07: Suggested Duration: 5 days Notes for Teacher What is the value of this nickel? (5 cents) How can you record the value of a nickel? (5¢) What is the value of this dime? (10 cents) How can you record the value of a dime? (10¢) 6. Instruct students to place their coins in order from greatest value to the least value. Demonstrate this process for the class using the displayed coins. Allow students to make self-corrections, as needed. 7. Instruct the class to chorally count the coins with you as they touch each corresponding coin: “10, 20, 25.” Next to the coins record: 10 + 10 + 5 = 25¢. 8. Remind students that 25 cents can be represented in a variety of ways, using other collections of coins. Instruct students to use their Bag of Coins to count out another collection of coins to represent 25 cents. Allow time for students to explore the possible combinations. 9. Invite various student volunteers to share their combination. Display the coins named by the student. Instruct the class to count the displayed collection aloud. As they orally count, touch each coin to confirm the count and value. Record the number sentence of each collection created for the class to see. 10. If time allows, challenge pairs of students to find as many different collections valued at 25 cents as they can, then compare lists to make a large class list of all the combinations. 2 Topics: Spiraling Review Unlike coin collections Coin collection value ATTACHMENTS page 9 of 31 Enhanced Instructional Transition Guide Suggested Day Grade 2/Mathematics Unit 07: Suggested Duration: 5 days Suggested Instructional Procedures Notes for Teacher Cent “¢” symbol Card Set: Money Collection Cards (1 set Explore/Explain 2 per 2 students) Students match a coin collection to a specific value.

Distribute a Bag of Coins to students and present the following scenarios to the class: The school vending machine is broken and will not accept quarters. Use your Bag of Coins to create various coin combinations you could use to buy a bag of chips for 50¢. 3. Invite students to display their collections and demonstrate counting the collection. Continue to Bag of Coins (14 pennies, 40 nickels, 20 dimes, 8 quarters, 4 half-dollars) (1 collection per student, 1 collection per teacher) (previously created) invite students to share their combinations until at least 4 different representations are shown and counted. Ask: Is it important to be able to represent a collection of coins in a variety of ways? page 11 of 31 Enhanced Instructional Transition Guide Suggested Day Suggested Instructional Procedures Grade 2/Mathematics Unit 07: Suggested Duration: 5 days Notes for Teacher Explain. Answers may vary. 4. Present a new scenario to the class: My coin purse is too full to close. To minimize the amount of coins I want to trade the following coins for quarters: 10 pennies, 3 dimes, and 6 nickels. How many trades would I be able to make? Ask students to use their Bag of Coins to represent a minimal collection of the coins in your purse. 5. Invite a student to display their trades and demonstrate counting the collections. Ask students how they would represent the value of each of the collections demonstrated. Record the representations on the board. 6. Explain to students that they have represented the value of money using the word “cents” and the cent symbol “¢.” Today they will be introduced to symbols that can be used in place of the word “cents” or the cent symbol “¢.” 7. Display the decimal and the dollar symbol from teacher resource: Teacher Money Symbols. Explain to students that these two symbols are always written together when representing the value of money less than a dollar or if there is a combination of dollars and cents, however they will never be used in combination with the cent symbol “¢.” 8. Using the decimal symbol from teacher resource: Teacher Money Symbols explain to students that this symbol is called a decimal point. Demonstrate pointing to the appropriate area on either side of the decimal point and describe how the decimal is used to separate the whole dollar amounts from the parts or fractions of a dollar. Explain to students that the whole dollar amounts are always written between the dollar symbol and the decimal point, or to the left of the decimal page 12 of 31 Enhanced Instructional Transition Guide Suggested Day Suggested Instructional Procedures Grade 2/Mathematics Unit 07: Suggested Duration: 5 days Notes for Teacher point. 9. Record the money amounts for one penny, one nickel, one dime, one quarter, two quarters, three quarters, four quarters, and a half-dollar using the dollar symbol and decimal point. ($0.01, $0.05, $0.10, $0.25, $0.50, $0.75, $1.00, $0.50) Facilitate a class discussion about how money amounts with no whole dollars are recorded with a zero to the left of the decimal. 10. Distribute handout: Recording Coin Collections to each student. Display the card from card set: Teacher Writing Money that represents 28 cents. Instruct students to take out matching coins from their Bag of Coins to represent the amount displayed on the card. Ask: What is the value of the collection of coins on this card? (28 cents) 11. Demonstrate counting the collection of coins, pointing to each corresponding coin as you count. “10, 20, 25, 26, 27, 28.” Ask: Does this collection of coins make a whole dollar? Explain. (No, because you need 100 cents to make a whole dollar.) Will you write this amount on the left or the right of the decimal on your handout? Explain. (On the right because it is less than one dollar.) What could you write between the dollar symbol and the decimal point? Explain. (A zero because I do not have any whole dollars.) 12. Demonstrate how to record 28 cents using dollar and decimal notation. Ask: page 13 of 31 Enhanced Instructional Transition Guide Suggested Day Grade 2/Mathematics Unit 07: Suggested Duration: 5 days Suggested Instructional Procedures Notes for Teacher How can you write this value using the cents sign? (I could write 28 before the cents sign.) 13. Allow time for students to fill in the correct notation on their handout: Recording Coin Collections. Remind students that it is never correct to use a cent symbol and a dollar symbol at the same time. Only the cent symbol alone or the dollar symbol and decimal point can be used to represent the value of the collection, but never together. 14. Repeat the activity again with another card from teacher resource: Teacher Money Symbols by displaying the card and instructing students to model the representation with coins from their Bag of Coins. Facilitate class discussions about the value of the collection, if the collection makes a whole dollar, and how the value can be represented with the dollar symbol and decimal point or with the cent symbol. Allow time for students to record the correct notations for each collection of coins. 3 Topics: Spiraling Review Unlike coin collections Coin collection value MATERIALS Cent “¢” symbol Dollar symbol cup (1 per 2 students) Decimal plate (paper) (1 per 2 students) Bag of Coins (14 pennies, 40 nickels, 20 Elaborate 1 dimes, 8 quarters, 4 half-dollars) (1 Student pairs spill coins onto a paper plate.

Instruct students to begin the activity. Allow time for students to complete 2 spills. Monitor and assess student pairs to check for understanding and to observe counting strategies. 4. Distribute a sheet of paper to each student. Instruct students to repeat the activity 2 more times, recording their first spill on the front side on their paper and the second spill on the back side of the same piece of paper by tracing around each of the coins they are assigned to count, and marking each coin with the first letter of its name to distinguish the coin recorded. Allow time for students to record their two spills. Monitor and assess student pairs to check for understanding. 5. Instruct students to count their recorded coin collection and record how they counted the sum using the cents symbol and/or decimal notation. Allow time for students to complete the record. Monitor and assess students to check for understanding and to observe counting strategies.
