Spotting mathematical patterns

Notice simple patterns and structures: spot that changing order doesn't change the total, and recognise how numbers relate to each other

What a learner can do afterwards

  • Notice that 3 + 2 gives the same answer as 2 + 3 (early commutativity)
  • Recognise that teen numbers are 'ten and some more' (e.g. 14 is 10 and 4)
  • Spot a pattern in a sequence of objects or numbers and predict what comes next

The lesson

You can swap the order of two numbers you add. The answer stays the same.

Tap each star and count out loud.
3 stars, then 2 more. Or 2 stars, then 3 more. Both make 5.
Try it together

Ben has 4 red cubes and 3 blue cubes. That makes 7 cubes. He counts blue first, then red. He still gets 7.

Tap each block and count out loud.

Numbers can show a pattern too. Teen numbers are ten and some more. 14 is 10 and 4.

Good to know

Look for a pattern in a row of numbers. Ask what changes each time. Then guess what comes next.

Order can change, but the answer stays the same, and patterns help you guess what comes next.
