Year 7 maths: what your child learns

Maths equipment
As your budding mathematician moves up to secondary school and starts KS3 maths, what new skills will they learn?

KS3 maths is usually taught in ability sets: this means the more able children will be stretched, while children who struggle with maths will take things more slowly, and be given more support.

Your child will find some of the work similar to primary school, but it will be more challenging and the children are expected to be working more independently.

With all the topics the children will be studying, they’ll be developing ‘mathematical process’ skills, which include reasoning, analysis and evaluation.

Y7 maths – your child will be learning from the following topics:


Preparing for Y7 maths at home

  • If your child has a mobile phone, set them the task of finding the best tariff
  • Encourage your child to look out for percentages: in a newspaper, in shops, or on adverts for credit cards
  • Practise maths when you’re out shopping or in a restaurant – get your child to add up prices, work out how much you can save on special offers, and estimate the total bill
  • If your child enjoys maths and wants to be stretched, ask if your school has a maths club
