Use part-part-whole structures to solve additive problems in a range of contexts

In this unit pupils will identify structures within stories. They will use their knowledge of structures to create stories and use their knowledge of additive structures to solve problems. In the future it pupils will use the concept of 'same sum' to simplify and solve addition problems.

In the prior unit pupils used the most efficient and reliable strategy to find the change. In this unit pupils will  identify structures within stories and use their knowledge of structures to create stories and use their knowledge of additive structures to solve problems.

In this unit pupils will identify the mathematical structures within stories and use their knowledge of additive structures to create stories and to solve problems.
