Unit I – Subtraction Problems
This maths scheme of work for Key Stage One gets the children to identify and practise techniques that can be used when solving number problems related to subtraction using concrete objects and diagrams to support calculations. The class can explain how to record solutions to problems using matching number sentences.

Lesson One : Subtraction Match
Identify and record a range of subtraction number calculations that can match different sums to ten using diagrams to model each number sentence
Lesson Two : Subtraction Sums
Identify and record different pairs of subtraction number sentences that have matching sums to ten using pictorial diagrams to illustrate the calculations
Lesson Three : Kitchen Cupboards
Identify and record number sentences that can be used to solve problems involving subtraction of single digit numbers within ten about items found in a family kitchen
Lesson Four : Subtraction Stories
