28) Fluency
Bonds of 10: Tic-Tac-Toe

Mathematics
Develop the fluency with two-part bonds of 10.
Language
- addition as “and”
- equals as “is”

Differentiation
A little easier
Place blocks on the game board
Support students experiencing difficulty by placing blocks on the Part-Part-Whole frame.
For example, spinning 3.

For example, spinning zero.
When using the Part-Part-Whole frame it is important to be clear that the whole on the top row is worth the same as the parts joined underneath. This is NOT a diagram of 10+10=20


For example, spinning zero.

For example, spinning ten.

A little harder
Three-part bonds
Develop fluency with three-part bonds of 10.
An activity for pairs:
- Player One closes their eyes.
- Player Two builds a three-part bond of 10, then hides one of the parts.
- Player One opens their eyes and guesses the hidden block.
- Player Two returns the block to confirm the guess.
- Swap roles.
