P3 Maths Overview

This is an overview of the topics we would cover in Primary 3. 

It will help you know what we should be covering in class.

Remember every child has their own strengths and will not cover the same work. 

Each week we will concentrate on one or two areas but you can keep revising work we have already covered.

Remember we cover lots of the activities through practical work and investigation!

Get those weighing scales and jugs out in the kitchen!
