**Operations & Algebraic Thinking (OA) 1.OA.B3**

**1.OA.B.3**

Apply properties of operations as strategies to add and subtract. 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.)

**Operations & Algebraic Thinking (OA) 1.OA.D7**

**1.OA.D.7**

Understand the meaning of the equal sign, and determine if equations involving addition and subtraction are true or false. For example, which of the following equations are true and which are false? 6 = 6, 7 = 8 â€“ 1, 5 + 2 = 2 + 5, 4 + 1 = 5 + 2.

**Measurement & Data (MD) 1.MD.A2**

**1.MD.A.2**

Express the length of an object as a whole number of length units, by laying multiple copies of a shorter object (the length unit) end to end; understand that the length measurement of an object is the number of same-size length units that span it with no gaps or overlaps. Limit to contexts where the object being measured is spanned by a whole number of length units with no gaps or overlaps.
