# Math Practice #7:

### Look for and make use of structure

## I can derive mathematical rules that make sense of the world around me!

__Important Questions__*“Is there a pattern in the problem situation?”**“Can I state the pattern or structure as a rule?”**“Is this a rule that holds true every time?”**“If the rule does not work every time, can I adapt it to work every time?”*

## Math Practice #8

## Look for and express regularity in repeated reasoning!

## I see a pattern...

Given the numbers 6, 7, and 8, I notice that 7 x 7 is one bigger than 6 x 8.

Also, given the numbers 8, 9, and 10, I notice that 9 x 9 is one bigger than 8 x 10.

So maybe, 44 x 44 is one bigger than 43 x 45...
