17) Fluency Doubles
Doubling and Halving to 10: Filling a Wall
Mathematics
Develop fluency with double bonds for the wholes 2, 4, 6, 8, 10.
Language
- double bond: a two-part bond, where both parts are the same
- double
- equals as “is”

Activity 58
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 58 Doubling and Halving to 20: Fluency Doubles Filling a Wall.
Progression
In the next activity students apply double bonds, to finding half of the whole, when wholes are presented in random order. Go to
