About this activity
What your child practises
Quick, accurate calculation and recall of number facts, building the fluency harder maths depends on.
What’s included
- 10 questions
- An answer key you can print with the sheet or on its own
- An on-screen version with instant marking and stars
Age and school year
Made for ages 12–13. That’s Grade 7–8 in the US, Year 8–9 in England, JSS 1–2 in Nigeria and Class 7–8 in India.
How to use it
- Print it at home or school – it fits a standard A4 or US Letter page.
- Print the answer key too, so marking takes seconds.
- Play it on screen: answers are marked instantly and children earn stars.
- Write on it on a tablet or touchscreen with a finger or stylus – no printer needed.
Tips for parents and teachers
- Time one try, then beat it a few days later – children love racing their own best rather than others.
- Let your child mark the sheet with the answer key; spotting their own mistakes is a skill in itself.
- Use a fresh printed copy as a short timed test before an exam to practise working under pressure.
