About this activity
What your child practises
Skills: Standard form (scientific notation) (level 2).
Applying a method step by step and checking the answer – the skills secondary-school maths tests are built on.
What’s included
- 15 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 12–18. That’s Grade 7–12 in the US, Year 8–13 in England, JSS 1 – SS 3 in Nigeria and Class 7–12 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
- Ask for the working, not just the answer – in exams, clear method earns marks even when the answer slips.
- Redo three of the questions a week later: spaced recall is one of the surest ways to make methods stick.
- Use a fresh printed copy as a short timed test before an exam to practise working under pressure.
