- 50×18.
- 120×5.
- 25×20.
What is the double strategy?
The Using Doubles strategy involves decomposing one addend to make a double with the other addend. For example 7 + 8 is the same as 7 + 7 plus 1 more. Double ten frames are great for exploring the strategy. Have students build each addend on a different ten frame using two-color counters.
