Algebra problems for 11 plus
Algebra is a key part of the 11+ maths exam. Children are expected to solve problems with unknown values and simple equations. Regular practice helps build confidence and accuracy.
Why algebra matters
Learning to solve algebra problems supports logical thinking. It teaches children to follow clear steps and check their answers carefully. This is a skill that helps across all areas of maths.
Worked example
Solve 3x + 5 = 17
First, subtract 5 from both sides:
3x = 12
Next, divide both sides by 3:
x = 4
The solution is x = 4.
Key insight: Practising a variety of algebra problems helps children spot patterns and choose the right method. Encourage your child to write each step clearly, so mistakes are easier to find and fix.
Supporting your child
Start with simple equations and build up to more challenging problems. Use practice worksheets and encourage your child to explain their thinking out loud. This helps them understand and remember each step.
