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

Create stories to match structures presented in a model

Maths

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

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

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

The bar model does not show three equal teams of 13

Three equal groups of 13 does not total 36

Each football team has 13 players including substitutes playing in a tournament. There are 36 footballers in total. What is the mistake in the bar model?

In the dining room at lunchtime, 42 children can sit at 6 tables with 7 seats at each table.  However, 4 children were away. How could the bar model be adjusted?

Cheese sandwiches could change to 52 and tuna sandwiches could change to 27

On a school trip, 54 children asked for cheese sandwiches, 37 wanted meat sandwiches and 29 asked for tuna fish. However, 5 children didn’t go on the trip. How could the bar model be adjusted?
