Take turns to choose two bugs so that the numbers on their backs add up to 10.

bottletop bugs add to 10

What do you think?

How many pairs of numbers can you find to make 10?

How do you know you have found all the pairs?

Write a number sentence to go with each of your pairs.

Make up word problems using your pairs of numbers.

What if.…………

…….you looked for 3 numbers which, added together, make 10?

……you weren’t making 10?

…….you looked for numbers with a difference of 1? What do you notice?

…….you made up some of your own questions?

If you don’t have Bottle Top Bugs you can do the same activity with:
