## Operations and Algebraic Thinking

- 4.OA.1 I can understand that multiplication equations can be seen as comparisons of groups (e.g., 35 = 5 x 7 is the same as saying that 35 is 5 times as many as 7 and 7 times as many as 5.)
- 4.OA.2 I can multiply to solve word problems by using drawings and equations that have symbols for unknown numbers.
- I can divide to solve word problems by using drawings and equations that have symbols for unknown numbers.
- 4.OA.3 I can solve multi-step word problems involving whole numbers using what I know about addition, subtraction, multiplication, and division. 1 2 3 I can represent word problems by using equations with a letter standing for an unknown number. I can decide if my answers are reasonable by using mental computation and estimation (including rounding.)
- 4.OA.4 I can find all factor pairs for a whole number between 1–100.

- I can tell whether a whole number between 1–100 is prime or composite.
- 4.OA.5 I can create a number or shape pattern that follows a given rule.
- I can multiply and divide using the Associative property. (3 x 5 x 2 can be found by 3 x 5 = 15, then 15 x 2 = 30)
- I can identify features of a pattern even though the features of the pattern were not obvious in the rule.
