58) Fluency Doubles
Doubling and Halving to 20: Filling a Wall
Mathematics
Develop fluency with double bonds for the wholes 12, 14, 16, 18.
Prior knowledge of ten plus bonds and part-part-whole is required.
Language
- double bond: a two-part bond, where both parts are the same
- double
- equals as “is”
Differentiation
A little easier

Activity 17
Activity 17, Doubling and Halving to 10: Fluency Doubles Filling A Wall is the same activity but for wholes up to 10. This is significantly easier.
Progression
In the next activity, students repeat this fluency activity, but do so using one half of a double bond. Go to
