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

Activity 18
Activity 18, Doubling and Halving to 10: Fluency Halves Filling A Wall is the same activity but for wholes up to 10. This is significantly easier.
Progression
In the next two activities students continue to develop fluency with double bonds but do so without using the blocks. Go to
