Fascinating Fact:

Adding means joining groups together. Two apples and three apples make five apples.

In KS1 Maths, children practise addition by joining sets and counting on. They use number lines, cubes, and simple number sentences to find totals. Try our quick practice here: Play the Addition Game to build speed and confidence.

  • Add: To join amounts together to make a bigger total.
  • Sum: The answer you get when you add numbers.
  • Number sentence: A maths line that shows a calculation, like 2 + 3 = 5.
What does add mean in Year 1 maths?
