Two expressions are equivalent if they have the same value.

Explain how a combination of different parts can be equivalent to the same whole

Maths

Identify structures within stories and use knowledge of structures to create stories

Identify the missing part using knowledge of relationships and structures

Use a model to interpret a part-part-whole problem with three addends

Create stories to match structures presented in a model

Use knowledge of additive structure to solve problems

Use mental strategies and known facts to calculate the value of a missing part

Use written strategies and known facts to calculate the value of a missing part

Represent an equation in a part-part-whole model correctly

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.

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