An adjustment is a change to a number using either subtraction or addition.

Capacity is the amount that something can hold.

Solve addition calculations mentally by using known facts in a range of contexts

Maths

In this unit pupils used the concept of same sum to simplify and solve addition problems. In the future unit pupils will solve calculations with missing addends and use the same difference rule to balance equations. They will explain how increasing or decreasing the minuend affects the difference.

In the prior unit pupils identified structures within stories using their knowledge of structures to create stories. They used their knowledge of additive structures to solve problems. In this unit pupils used the concept of same sum to simplify and solve addition problems

Use equivalence and compensation to simplify and solve addition calculations

Capacity is the willingness to do something. 

Which of the following describes capacity?
