### Mathematics

Develop the concept of using bonds of 5 in subtraction equations, expressed verbally.

### Language

• subtract
• equals
• part-part-whole

## Differentiation

### A little easier

##### Build a wall

Build a wall of 5 that requires students to use the commutative property of addition to identify two-part bonds. Use one of each block from 1 to 5. Keep this on the game board whilst playing.
