## Operations & Algebraic Thinking

## Understanding that a multiplication equation can be seen as comparing two numbers. e.g. 48 = 6 x 8 is the same as saying 48 is 6 times as many as 8.

The listing of worksheets and other math resources below are related to the following standard extracted from the *Common Core Standards For Mathematics*:

Interpret a multiplication equation as a comparison, e.g., interpret 35 = 5 x 7 as a statement that 35 is 5 times as many as 7 and 7 times as many as 5. Represent verbal statements of multiplicative comparisons as multiplication equations.
