Part-whole model subtraction
This tutorial shows how a part-whole model can be used to make four number sentences. For example:
- 4 + 3 = 7
- 3 + 4 = 7
- 7 – 4 = 3
- 7 – 3 = 4
Being able to see this connection between addition and subtraction is crucial for children’s ability to calculate quickly. We have included it in our Subtraction category but it is equally valid for Addition.
