21 October 2026

Algebra reasoning made simple
Algebra reasoning is a key skill for 11+ maths. It helps children solve problems where numbers are replaced by letters or symbols. Regular practice with clear worksheets can make this topic much less daunting.


Why algebra reasoning matters
In 11+ exams, pupils often face questions that require them to find unknown values or understand relationships between numbers. Building strong algebra reasoning skills early can help your child approach these questions with confidence.
Step-by-step: solving an algebra equation
Let's look at a simple example together.


Worked example
3x + 5 = 20
Step 1: Subtract 5 from both sides. 3x + 5 - 5 = 20 - 5, so 3x = 15.
Step 2: Divide both sides by 3. 3x ÷ 3 = 15 ÷ 3, so x = 5.
The answer is x = 5.
How to support your child
Encourage your child to practise similar questions and talk through each step aloud. This helps make the process clear and builds their ability to explain their reasoning.


Key insight: Regular practice with algebra reasoning worksheets helps children develop the confidence and skills they need for 11+ maths success.
