Mathematics
Develop the concept of using bonds of 5 in subtraction equations, expressed verbally.
Language
- subtract
- equals
- part-part-whole
Differentiation
A little easier
Working Memory Support: 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. The bond wall is a visual to support students with working memory difficulties. Using the bond wall helps to free up the working memory to focus on applying the bond.
