Algebra word problems in the 11+
Many 11+ maths papers include algebra questions disguised as story problems. These often ask your child to find an unknown number, or to solve a puzzle involving two numbers. The key is to turn the words into a clear equation.
A calm step-by-step method
Start by reading the problem slowly. Identify the unknown. Often called 'the number', and use a letter such as n or x. Translate each step in the story into a mathematical operation. For example, 'double it and add five' becomes 2n + 5.
Solving the equation
Once you have your equation, use inverse operations to solve for the unknown. Work backwards: undo any addition or subtraction first, then any multiplication or division. Write each step clearly, so your child can see the logic.
Checking the answer
Encourage your child to check their answer by putting it back into the original story. Does it make sense? If the story says 'double the number and add five gives seventeen', try the answer: double, add five. Do you get seventeen?
Key insight: Translate, solve, check
Every algebra word problem for 11+ can be tackled with three calm steps: translate the story into an equation, solve for the unknown, and check the answer against the story. Practising this routine builds confidence and accuracy.
