Year 4 maths: what your child learns

Red calculator
Want to know what subjects will be the focus in maths lessons in year 4? Find a detailed breakdown here.

As with reading and writing, by year 4 most children have a good grasp of the basic maths skills and their mental maths recall is becoming more automatic. It’s important by now that the children have a good knowledge of their times tables up to ten. The children will be starting to develop their own ideas of how to solve maths problems, and how to check that their calculations are correct. Calculators may be introduced in this year, and your teacher will show the children how to use them correctly. Maths is still taught daily through a mix of oral, practical and written work, and the children are given plenty of opportunities to see how maths links to other areas of the curriculum, and real-life situations.

Year 4 maths – your child will be:

Counting, partitioning and calculating

  • Mentally adding and subtracting one- and two-digit numbers
  • Adding and subtracting two- and three-digit numbers using the written method
  • Working through one- or two-step problems using money, time or measures
  • Ordering, partitioning and rounding four-digit numbers
  • Revising times tables up to ten
  • Calculating doubles and halves
  • Working with positive and negative numbers
  • Using decimals to represent tenths and hundredths
  • Learning about fractions and mixed numbers
  • Working with remainders
  • Using a calculator


  • Learning about patterns and properties of shapes
  • Understanding line symmetry
  • Finding fractions of shapes
  • Visualising 2D and 3D shapes
  • Making solid shapes
  • Understanding that angles are measured in degrees
  • Calculating the area and perimeter of rectangles
  • Plotting horizontal and vertical positions on a grid
  • Learning about compass points

  • Using ICT to present information and results

Try this at home

  • Keep on with the times tables – automatic recall really does help at school and with homework. Practise in the car or on the way to school, set your child a challenge, play times tables games and, if necessary, offer a small reward as motivation
  • If your child has weekly pocket money, encourage them to save and work out how much they will have after two, three or four weeks
  • Go on a walk and give your child a compass so they can keep track of your direction
