About this activity

What your child practises

Skills: Mean (average) (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

  1. Play it on screen for instant feedback, then print a fresh version as a timed, calculator-free check.
  2. Check answers after each block of questions so a misconception is caught before it is practised.
  3. Treat mistakes as information: note what went wrong next to each incorrect answer.
