UT PUBLICATION NO.: R01-1704-113-002-13 Purpose of This Booklet This booklet has two goals: ■ to help parents understand more about what their children are learning in school, and ■ to help students know if they have mastered the skills their teachers expect them to know in each grade This booklet will explain what the Common Core State Standards are, and about the skills on which Tennessee teachers will focus math instruction while transitioning to the Common Core State Standards. You will find general information that will give you an overview of what the standards are and why states are using them. At the end of each grade’s lists of standards and explanations, you will find a box with an “I can do it!” checklist. These are short statements about the skills your children will be expected to have mastered by the end of the year. Ask your children to look at them to see if they feel they have mastered those skills, or if they need some extra help in specific areas. T eachers work from a set of standards that tell them what to teach. Each state has created its own standards, and those standards have not been the same across our country. However, most states have recently agreed to use the same set of standards — the Common Core State Standards. More information is included about the Common Core State Standards in the following pages. We hope you will find this booklet helpful in your effort to be a partner in your child’s education and development. If you come across a math term and don’t remember what is or what it means, check out the Math is Fun dictionary at www.mathisfun.com/definitions 2 What are the Common Core State Standards? A will balance procedural skills with understanding by finding find ways to engage students in good practices that will help them understand the math content as they grow in math maturity and expertise throughout the elementary, middle, and high school years. cademic standards are statements that describe the goals of schooling — what children should know or be able to do at the end of the school year. For example, the second grade math standards state that by the end of the school year, a second grader should be able to count to 120 and understand what each digit in a three-digit number represents. The Common Core State Standards will provide students, teachers, and parents with a shared understanding of what students are learning. With students, parents, and teachers all on the same page and working together for shared goals, we can increase the likelihood that students will make progress each year and will graduate from school prepared to succeed and to build a strong future for themselves and the country. However, standards have not been the same across the United States. In the past, states have had their own sets of standards. This means that children in one state may be learning different things at different times (and in different years) than children in another state. Many states have recently agreed to use a common set of standards for learning that takes place in their classrooms; these are the Common Core State Standards (CCSS). Parents: In this booklet, you will find an overview of the standards for each grade, showing you what your children should be able to do by the end of the school year. At the end of the section, you will find a box with this “I can do it!” symbol. Discuss these items with your child to see if he/she is able to complete these tasks. One major benefit of having common standards across states is that children are being required to learn the same information in the same years in each of those states, so that a child moving from one state to another will not be behind the children in the new location. A common set of standards ensures that all students, no matter where they live, are focused on graduating from high school prepared for postsecondary education and careers. Students: Find the “I can do it!” box at the end of each section and check yourself to see if you can do all those things. The Common Core State Standards for Math have two components: Standards for Mathematical Practice and Standards for Mathematical Content. The Practice Standards describe the kind of math teaching and learning that will produce the most successful learning and that will help students dig deeper and better understand math. The Content Standards outline the concepts and skills to be learned in each grade; teachers 3 I can do it! Overview of Goals for Standards for Mathematical Practice The Standards for Mathematical Practice describe skills and behaviors that all students should be developing in their particular grades. These practices include important processes (ways of doing things) and proficiencies (how well we do things), including problem solving, reasoning and proof, communication, representation, and making connections. These practices will allow students to understand and use math with confidence. Following is what children will be working to be able to do with increasing ease: Construct arguments and evaluate the reasoning of others UÊ1`iÀÃÌ>`Ê>`ÊÕÃiÊvÀ>ÌÊ to build arguments UÊ>iÊ>`ÊiÝ«ÀiÊÌ iÊÌÀÕÌ ÊvÊ estimates and guesses UÊÕÃÌvÞÊVVÕÃÃÊ>`ÊÀië`Ê to arguments of others Model with mathematics UÊ««ÞÊ>Ì ÊÌÊ«ÀLiÃÊÊ everyday life UÊ`iÌvÞʵÕ>ÌÌiÃÊ>ÕÌÃ]Ê numbers) in a practical situation UÊ*ÀiÃiÌ]Êà Ü]ÊÀÊiÝ«>ÊÌ iÊ problem and solution in an understandable way Make sense of problems and persevere in solving them UÊ`ÊÌ iÊi>}ÊÊ«ÀLià UÊ>Þâi]Ê«Ài`VÌ]Ê>`Ê«>ÊÌ iÊ path to solve a problem UÊ6iÀvÞÊ>ÃÜiÀà UÊÃÊÌ iÃiÛiÃÊÌ iʵÕiÃÌ\Ê “Does this make sense?” Use appropriate tools strategically UÊ Ã`iÀÊÌ iÊ>Û>>LiÊÌÃÊ when solving problems, and know which tool is most appropriate in the situation UÊiÊv>>ÀÊÜÌ ÊÌÃÊ appropriate for their grade level or course (pencil and Reason abstractly and paper, concrete models, quantitatively ruler, protractor, calculator, UÊiÊ>LiÊÌÊÌÀ>Ã>ÌiÊÌ iÊi>}Ê spreadsheet, computer of each math term in any programs, digital content on a iµÕ>Ì website, and other technological UÊÌiÀ«ÀiÌÊÀiÃÕÌÃÊÊÌ iÊVÌiÝÌÊ tools) (setting) of the situation Be precise UÊiÊ>LiÊÌÊVÕV>ÌiÊ accurately with others UÊ1ÃiÊVi>ÀÊ`iwÌÃ]ÊÃÌ>ÌiÊÌ iÊ meaning of symbols, and be careful when specifying units of measure and labeling axes (the “x” and “y” lines that cross at right angles to make a graph) in math figures UÊ >VÕ>ÌiÊ>VVÕÀ>ÌiÞÊ>`Ê efficiently Look for and make use of structure UÊ,iV}âiÊ«>ÌÌiÀÃÊ>`Ê structures UÊ-Ìi«ÊL>VÊÌÊw`ÊÌ iÊL}Ê«VÌÕÀiÊ and be able to shift perspective UÊ-iiÊV«V>Ìi`ÊÌ }ÃÊ>ÃÊ single objects, or as being made up of several objects Look for and identify ways to create shortcuts when doing problems UÊ7 iÊV>VÕ>ÌÃÊ>ÀiÊÀi«i>Ìi`]Ê look for general methods, patterns, and shortcuts UÊiÊ>LiÊÌÊiÛ>Õ>ÌiÊÜ iÌ iÀÊ>Ê answer makes sense The major domains included in the math standards for Grades K-5 are listed below.

While these skills are priority areas, students will be learning all of the skills listed in the following sections. For fourth graders, the math standards expect the following skills to be developing, so that a student can say, “I can … (insert math goal),” for example, I can explain why one fraction is equal to another.” Help your child develop skills in these areas: Numbers and Operations – Fractions ■Ê Ý«>ÊÜ ÞÊ>ÊvÀ>VÌÊ>ÉLÊÃÊiµÕÛ>iÌÊÌÊ>ÊvÀ>VÌÊ 3____ x 6 18 6 = __ = _ (n x a)/(n x b) (n being any number) by using visual fraction models. 3 x 8 24 8 Multiplying by the same number in the numerator (top or first number) and denominator (bottom or second number) gives the same fraction.

But 6 can be divided evenly by 1, 2, 3 and 6 so it is NOT a prime number (it is a composite number). 28 ■Ê iiÀ>âiÊ>`Ê>>ÞâiÊ«>ÌÌiÀð UÊ iiÀ>ÌiÊÃiÛiÀ>ÊÕLiÀÊ«>ÌÌiÀÃÊÌ >ÌÊvÜÊ>Ê}ÛiÊÀÕi°Ê`iÌvÞÊ>««>ÀiÌÊvi>ÌÕÀiÃÊ of the pattern that were not explicit in the rule itself.
