Following Units 7-11

These activities bring together the different mathematical skills that your child should now know. By combining these skills in puzzles and activities your child will need to reason and think of solutions, as well as complete calculations. This will help your child to really understand the skills they are learning.

Talk through each group of questions and ask your child how they are going to solve the challenges.

It’s good to get stuck sometimes! When this happens discuss the challenge in the following order:

  • What do we need to find out to solve the challenge?
  • What do we know by looking at the question?
  • Want could we do first?
  • How would that help us?

Is there anything else we could do?
