Grade 1 (1.OA.B.3) Understand and apply properties of operations and the relationship between addition and subtraction
Ages 6 - 7

## Caterpillar Chaos

EXTENDS 1.OA.B.3: Apply properties of operations as strategies to add and subtract.2 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.)
