Retrieval practice is one of the most effective ways to strengthen long-term memory. In maths, that means regularly revisiting core skills so that number, algebra, geometry, ratio and statistics stay sharp. The challenge for teachers is finding good retrieval questions that are quick to use, easy to mark, and varied enough to keep students engaged.
That's why we created a free resource: 50 Retrieval Starters – one page per starter, five questions each, with full answers. You can print them, project them, or use them as do-now tasks at the start of every lesson. They cover the topics that come up most in KS3 and GCSE maths, so you get spaced practice without the planning time.
Why use retrieval starters?
Short, focused starters at the beginning of a lesson help to:
- Settle the class – students know what to do as soon as they sit down.
- Revisit prior learning – retrieval strengthens memory and highlights gaps.
- Mix topics – a few questions on number, algebra or geometry each day keep the full curriculum in rotation.
- Save time – no need to hunt for a suitable starter when you have 50 ready to go.
What's in the 50 Retrieval Starters pack?
The pack is organised into six sections:
- Number – four operations, decimals, negatives, fractions, percentages, rounding, BIDMAS.
- Algebra – simplifying, expanding, factorising, solving equations, substitution, sequences.
- Geometry – angles, area, perimeter, Pythagoras, volume, coordinates.
- Ratio and proportion – simplifying ratios, sharing, direct proportion.
- Probability and statistics – simple probability, averages, range.
- Mixed and challenge – combined topics and higher-tier style questions.
Each starter is one page: five questions and an answers line at the bottom, so students can self-mark or you can go through them quickly on the board. They're designed to take about five minutes – long enough to activate prior learning, short enough not to eat into the main lesson.

If you want to adapt the starters for your classes or project them on the board, we also offer a free editable PowerPoint version when you sign up – so you can tweak difficulty or add your own questions.
Using retrieval starters in your lessons
Use one starter per lesson at the start of the hour. Let students work in silence for four or five minutes, then either project the answers for self-marking or take a quick show of hands for each question. You can cycle through the 50 so that over a half-term you've revisited a wide mix of topics. For revision periods, pick the mixed and challenge starters to give a broader brush across the curriculum.
Retrieval practice works best when it's regular and low-stakes. These 50 starters are designed to slot into that routine with zero extra planning – so you can focus on the main lesson while still keeping core skills sharp.
