Negative numbers practice for 11 plus
21 October 2026
Negative numbers explained
Negative numbers are numbers less than zero. They are written with a minus sign, such as -3 or -10.
Children will meet negative numbers in 11+ maths, especially in GL and CEM style questions. These often involve temperatures, bank balances, or number lines.
Key insight: Understanding how to move across zero is essential for solving negative number problems.
Adding and subtracting negative numbers
When adding a positive number to a negative number, move to the right on the number line. When subtracting, move to the left.
It helps to picture the number line and think about which direction to move.
Worked example
-3 + 7
Start at -3 on the number line.
Add 7 by moving 7 steps to the right.
After 3 steps, you reach zero. There are 4 more steps to take, which brings you to 4.
The correct answer is 4.
Practice tips for parents
Encourage your child to draw number lines for tricky questions. Use real-life examples, like temperature changes, to make negative numbers more familiar.
Practising with a mix of positive and negative numbers builds confidence and accuracy.
Key insight: Mistakes often happen when children forget to count across zero or mix up the direction. Slow, careful practice helps build strong understanding.
