20) Near Double
Doubling and Halving to 10: Strategy Fluency
To develop fluency using the strategy of near double addition, adding one more than the double bonds of 1, 2, 3, 4, 5.
Prior knowledge of double bonds 1, 2, 3, 4, 5 and the commutative property of addition is needed.
- double bond
- near double
- one more
- addition as “add”
A little easier
Place Bond Blocks on the part-part-whole frame to calculate the near double. For example,
A little harder
Students who have completed up to Ten Plus Bonds: Addition and Subtraction Ten and One can complete a similar activity for wholes in the teens. Complete Activity 63 Doubling and Halving to 20: Near Double Strategy Fluency.
