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 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)
• 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)
• 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.
There are always plenty of addition questions on the KS1 Arithmetic Paper. The pages below cover all styles of question from recent papers.
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 have popped up occasionally in the KS 1 Arithmetic Papers.
