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)

A tower of green connecting cubes has 8 cubes.
A tower of yellow connecting cubes has 2 cubes.
Show 2 different ways to make the towers have the same number of cubes.
Show your thinking using objects, drawings, numbers, or words.

Problem 2 (Lesson 12)
