Key takeaways

  • The level of challenge in maths will noticeably increase for learners in Year 8 
  • Our maths questions for Year 8 are designed to test learners across the breadth of the Year 8 maths curriculum
  • Students are expected to use multiple skills to solve more complex, multi-step problems this year

In Year 8, things take a step up in terms of difficulty for maths students. They’re faced with more challenging Year 8 maths questions meaning that practice is even more important this year to build up their confidence and ability.

With a particular focus on using previously learned skills to solve harder problems, there are frequent cross–overs of skills in each mathematical area. Maths questions for Year 8 students will usually require more than one step to get to the final answer, so it’s important to double-check all work!

We’ve compiled a list of maths questions Year 8 learners can use to help them with their revision across the whole curriculum. From algebra and number work to geometry and statistics, learners will find questions here that’ll give them plenty of practice for Year 8 maths.
