# Section C: Practice Problems Compare Story Problems

## Section Summary

## Details

We made cube towers that have the same number of cubes.

We can add 7 more blue cubes. We can take off 7 red cubes.

We solved story problems about “how many more” and “how many fewer.”

Elena has 4 pattern blocks. Tyler has 6 pattern blocks. How many fewer pattern blocks does Elena have than Tyler?

or

We learned that these problems can be solved with addition or subtraction.

## Problem 1 (Lesson 11)
