What is KS2 Maths? A Complete Guide for Parents

If your child is in Years 3 to 6, they are working through Key Stage 2 (KS2) Maths. This stage of the UK National Curriculum covers a huge amount of ground — from times tables and fractions in Year 3, all the way to algebra and ratio by Year 6. Understanding what your child is learning can make a real difference to how you support them at home.

What Are the KS2 Year Groups?

Key Stage 2 runs from Year 3 (ages 7–8) to Year 6 (ages 10–11). Children sit their KS2 SATs at the end of Year 6, which assess their progress in Maths and English before they move to secondary school.

What Topics Are Covered in KS2 Maths?

Year 3 Maths

  • Place value up to 1,000
  • Addition and subtraction with regrouping
  • Multiplication tables (2, 3, 4, 5, 8 and 10)
  • Fractions — halves, thirds, quarters
  • Measurement: length, mass, volume, money and time

Year 4 Maths

  • Place value up to 10,000
  • All multiplication tables up to 12×12 (tested in the Multiplication Tables Check)
  • Decimals up to two decimal places
  • Area and perimeter of rectangles
  • Statistics: bar charts and time graphs

Year 5 Maths

  • Place value up to 1,000,000
  • Fractions, decimals and percentages
  • Multiplication and division of large numbers
  • Properties of 2D and 3D shapes
  • Converting units of measurement

Year 6 Maths

  • Place value up to 10,000,000
  • Ratio and proportion
  • Introduction to algebra
  • Geometry: angles, coordinates and symmetry
  • Statistics: mean, median and mode

How Are Children Assessed in KS2 Maths?

At the end of Year 6, children sit three KS2 Maths SATs papers:

  1. Paper 1 — Arithmetic: 40 marks, 30 minutes. Tests calculation skills without a calculator.
  2. Paper 2 — Reasoning: 35 marks, 40 minutes.
  3. Paper 3 — Reasoning: 35 marks, 40 minutes.

Results are reported as a scaled score. A score of 100 means the child is working at the expected standard. Scores above 110 indicate greater depth.

How Can You Support Your Child at Home?

The best thing you can do is make maths feel like a normal, everyday activity rather than extra school work. Here are some practical ideas:

  • Times tables practice — 5 minutes a day from Year 3 makes a huge difference by Year 4.
  • Real-life maths — ask your child to calculate change at the shops, measure ingredients when cooking, or read timetables.
  • Interactive resources — platforms like Skoolmaths offer curriculum-aligned interactive lessons and worksheets by year group, so you can target exactly what your child is learning in class.
