Algebra in the 11+: what to expect

Most 11+ tests now include basic algebra. Here's what's actually tested and how to prepare.

The 11+ syllabus now includes basic algebra — particularly in CEM-style and independent-school papers. Children who haven't touched algebra arrive at the test confused. The good news: 11+ algebra is straightforward to teach.

What "algebra" means at 11+ level

It's not solving simultaneous equations or factorising quadratics. 11+ algebra typically involves:

Worked examples

Substitution

If x = 5, find 2x² - 3.
2(5)² - 3 = 2(25) - 3 = 50 - 3 = 47.

One-step equation

4y = 28. Divide both sides by 4. y = 7.

Two-step equation

5x + 2 = 17. Subtract 2 from both sides: 5x = 15. Divide by 5: x = 3.

Combining like terms

3a + 2b - a + 5b = 2a + 7b.

Word to expression

"A pencil costs y pence. A pen costs 5p more than a pencil. What does a pen cost?" Answer: y + 5.

The key concept

The letter just stands for a number we don't yet know. Anything we do to one side of an equation, we must do to the other.

Practice plan

15 minutes a day for 4 weeks is enough for most Year 5 children to be comfortable. Quest Arena's maths worksheets include 30 algebra sheets graded from foundation to top-tier 11+.
