NCTM National Council of Teachers of Mathematics DRAFT: North Carolina Department of Public Instruction - Navigating through Algebra in Grades 3-5 1 Navigating through Algebra in Grades 3-5 Lesson alignment with Common Core State Standards for Mathematics Chapter Lesson Title, Page Number and Goal Student Behaviors (Mathematical Practices) to Look For… CCSS Cluster/Standard Third Grade Chapter 1: Patterns Hundred-Board Wonders page 9 Goals: Given a rule, students will explore number patterns using a hundred board. Solve problems involving the four operations, and identify and explain patterns in arithmetic. 3.OA.9 Identify arithmetic patterns (including patterns in the addition table or multiplication table), and explain them using properties of operations. For example, observe that 4 times a number is always even, and explain why 4 times a number can be decomposed into two equal addends. This tasked could be modified for third by making the patterns for the students then have them identify the pattern. Chapter 2: Variables and Equations The Variable Machine page 39 Solve problems involving the four operations, and identify and explain patterns in arithmetic. 3.OA.8 Solve two-step word problems using the four operations. Represent these problems using equations with a letter standing for the unknown quantity. Assess the reasonableness of answers using mental computation and estimation strategies including rounding.3 Goals: The student will*explore the idea of variable as a symbol that can stand for any 3 This standard is limited to problems posed with whole numbers and having number of a set of numbers; *substitute numbers for variables whole-number answers; students should know how to perform operations in the conventional order when there are no parentheses to specify a particular (letters) to discover unknown order. values.

DRAFT: North Carolina Department of Public Instruction - Navigating through Algebra in Grades 3-5 2 Chapter 2: Variables and Equations I Spy Patterns page 48 Goals: The student will*partition the given array into different parts; *translate visual patterns into numerical expressions; Explore how equivalent numerical expressions represent the commutative and associative properties of operations. Understand properties of multiplication and the relationship between multiplication and division. 3.OA.5 Apply properties of operations as strategies to multiply and divide.2 Examples: If 6 × 4 = 24 is known, then 4 × 6 = 24 is also known. (Commutative property of multiplication.) 3 × 5 × 2 can be found by 3 × 5 = 15, then 15 × 2 = 30, or by 5 × 2 = 10, then 3 × 10 = 30. (Associative property of multiplication.) Knowing that 8 × 5 = 40 and 8 × 2 = 16, one can find 8 × 7 as 8 × (5 + 2) = (8 × 5) + (8 × 2) = 40 + 16 = 56. (Distributive property.) 6. Understand division as an unknown-factor problem. For example, find 32 ÷ 8 by finding the number that makes 32 when multiplied by 8. 2 Chapter 3: Functions That’s Odd! page 61 Goals: The student will*observe various patterns in an array; *represent observed visual patterns as numerical patterns; *represent a numerical pattern as a functional relationship.
