# KS1 Maths SAT Practice: Arithmetic

The Key Stage 1 Mathematics test changed considerably in 2016 and now consists of two papers, an Arithmetic Paper and a Reasoning Paper. The questions which have come up on the Arithmetic Paper take a similar format each year and include:

Addition

• addition missing number problems. Very simple addition sentences where the answer is given but another number is missing (e.g. 1 + ? = 5). There is usually at least one of these, keeping to numbers up to 10.

• addition facts to 20 displayed as a straightforward sum (e.g. 5 + 6 = ?)

• adding a single digit to a 2-digit number (e.g. 62 + 9 = ?)

• adding a 2-digit number and whole tens (e.g. 35 + 20 = ?)

• adding three 1-digit numbers (e.g. 3 + 4 + 5 = ?)

• adding three multiples of 10 up to 100 (e.g. 20 + 30 + 40 = ?)

• adding two 2-digit numbers (e.g. 23 + 45 = ?)

• adding a 2-digit number and a teen (e.g. 34 + 16 = ?)

• more addition missing number problems using larger numbers which are often multiples of 10 (e.g. 10 + ? = 40)

Subtraction

• simple subtraction missing number problems. Very simple subtraction sentences where the answer is given but another number is missing (e.g. 6 - ? = 2)

• subtraction facts to 20 (e.g. 18 – 6 = ?)

• subtracting a 1-digit number from a 2-digit number (e.g. 23 – 5 = ?)

• subtracting a teen from a 2-digit number (e.g. 44 – 12 = ?)

• subtracting two 1-digit numbers from a single digit (e.g. 9 – 3 – 2 = ?)

• subtracting two 2-digit numbers (e.g. 48 – 23 = ?)

• more subtraction missing number problems using larger numbers, usually 1-digit from 2-digits (e.g. 34 - ? = 29)

Multiplication

• knowing multiplication facts for the 2x, 5x and 10x tables (e.g. 4 x 5 = ?)

• knowing multiplication facts for the 3x and 4x tables (e.g. 3 x 4 = ?)

Division and fractions

• knowing division facts derived from the 2x, 5x and 10x tables (e.g. 20 ÷5 = ?)

• finding simple fractions of quantities (e.g. a quarter of 12 = ?)

We have sets of pages for each of these types of question all written using a similar layout to the SAT Papers themselves.

## Addition

There are always plenty of addition questions on the KS1 Arithmetic Paper. The pages below cover all styles of question from recent papers.

Add three 1-digit numbers.

## Subtraction

Typical subtraction questions found on the Arithmetic Paper.

## Multiplication and division

Multiplication and division questions mainly with 2x, 5x and 10x tables but can also cover the 3x and 4x tables.

## Fractions

Fractions have popped up occasionally in the KS 1 Arithmetic Papers.
