Ex. Drop one Ping-Pong ball into a Pringles can with hole cut into lid. Ex. Follow directions to add one counting block to a group. CCSS Math Pacing Guide Grade 1 Grade Level: 1st Standard with code: 1.OA.3 Apply properties of operations as strategies to add and subtract.3 Examples: If 8 + 3 = 11 is known, then 3 + 8 = 11 is also known. (Commutative property of addition.) To add 2 + 6 + 4, the second two numbers can be added to make a ten, so 2 + 6 + 4 = 2 + 10 = 12. (Associative property of addition.) 3 Students need not use formal terms for these properties. Domain: Operations and Algebraic Thinking Cluster: Understand and apply properties of operations and the relationship between addition and subtraction.
