Why this why now
This unit revisits the part-part-whole structure and its language to support pupils to make sense of, represent and solve addition and subtraction problems in a range of contexts. They use mental and written strategies to calculate the value of missing parts. This leads to using equivalence and compensation in both addition and then subtraction.
Prior knowledge requirements
- Understand the meaning of factor and multiple
- Represent addition and subtraction using bar models or part-whole diagrams
- Recognise inverse relationships between addition and subtraction
