Game 9: Erase

Chapter 2. Foundational Addition and Subtraction Facts

Targeted Facts: Combinations of 10

Using Erase for Math Fact Fluency:

  • Student focus is on making combinations of 10 (3 + 7, 2 + 8, 4 + 6, etc.)
  • Ten frames present a natural tool for helping students identify combinations of 10.
  • Students also need to know combinations of 10s to find missing addends as in 9 + __ = 10 or 7 + __ = 10.
  • This is the type of thinking behind the making 10 and pretend-a-10 strategies where students must know how many are needed to make 10 or how far away a number is from 10.
  • Erase is a particularly useful game for providing enjoyable and substantial practice in building this type of understanding.
