Use equivalence and compensation to simplify and solve subtraction problems

Year 6 • Maths
We've put the lessons in order helping you build on what you've learned before so it’s best to start with the first lesson of a unit.

Choose a lesson (10)

1
Explain and represent constant difference for subtraction
2
Explain how constant difference can make written calculations more efficient
3
Use constant difference to balance equations and find unknowns
4
Explain how increasing or decreasing the minuend affects the difference
5
Solve subtraction calculations mentally by using known facts
6
Explain how adjusting the minuend can make mental calculation easier
7
Explain how adjusting the subtrahend affects the difference: reduction structure
8
Explain how adjusting the subtrahend affects the difference: partitioning
9
Calculate the difference using knowledge of an adjusted subtrahend: difference structure
10
Use equivalence and compensation strategies to solve subtraction problems in a range of contexts
