## 28) Fluency

Bonds of 10: Tic-Tac-Toe

### Mathematics

Develop the fluency with two-part bonds of 10.

### Language

• 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.
