Year 2 Calculation - Addition
1 + 2 + 3 gives the answer 6. So does 3 + 2 + 1. It doesn't matter what order you add the numbers in, you still get the same answer.

Fascinating Fact:

Start at 27, count on 3: 28, 29, 30. Like climbing three playground steps.

In KS1 Maths, Year 2 pupils add by counting on, using number lines, and making friendly tens (like 7 + 3 → 10). These strategies build speed, accuracy, and confidence in addition.

  • Addition: Joining numbers to find a total, for example 14 + 6 = 20.
  • Count on: Start at one number and say the next numbers to add, like “27, 28, 29, 30”.
  • Number line: A line of numbers you hop along to add or subtract.

What is the easiest way to add in Year 2?

Count on from the bigger number using your fingers or a number line. For example, 27 + 3: say 28, 29, 30 to land on the answer 30.

How do friendly tens help with addition?

Friendly tens make totals simpler. If you can make 10 first, sums are easier: 8 + 2 = 10, then add the rest if there is more to add.

Should I add the bigger or smaller number first?

Start from the bigger number and count on the smaller. It uses fewer steps and helps you add more quickly and accurately.

Question 1
What is 8 + 9 + 7?
