About this activity
What your child practises
Skills: Adding within 100.
Quick, accurate calculation and recall of number facts, building the fluency harder maths depends on.
What’s included
- 20 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 8–12. That’s Grade 3–7 in the US, Year 4–8 in England, Primary 3 – JSS 1 in Nigeria and Class 3–7 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
- Let your child mark the sheet with the answer key; spotting their own mistakes is a skill in itself.
- If a question goes wrong, ask your child to show it with fingers, objects or a quick sketch, then try again.
- Pick a regular time – after a snack, say – so practice becomes a habit rather than a battle.
