To represent something means to show something in a different way.

Use knowledge of additive structure to solve problems

Maths

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.

Use knowledge of part-part-whole structure to solve additive problems
