3.2 Component 2: the four operations (calculator not allowed)

This content aims to develop the student’s understanding and use of the four operations.

Students will undertake calculations using mental arithmetic involving addition, subtraction, multiplication and division.

Procedures for making and recording assessments

Class work assessed by the teacher in response to the outcomes set out below, or assessed by an externally-set assignment.

In successfully completing this component, students will have demonstrated the ability to:

Outcomes	Notes/examples	GCSE reference
1.1 Add two whole numbers with a total up to 20	Zero can be one of the numbers Key words are add, sum, total, altogether Use the = sign to represent equality	N2
1.2 Subtract one number up to 20 from another	Zero can be the number subtracted Key words are take, take away, subtract, difference, how much more, how much less	N2
1.3 Understand and use the + and – signs to solve simple number problems	Work out 5 + 11 6 = 10 - ? Understand that subtraction is the inverse of addition	N2, N3

1.1 Add two whole numbers with a total up to 20

Zero can be one of the numbers

Key words are add, sum, total, altogether

Use the = sign to represent equality

1.2 Subtract one number up to 20 from another

Zero can be the number subtracted

Key words are take, take away, subtract, difference, how much more, how much less
