Making totals

Digit Dog and Calculating Cat are using 4 bottletop bugs (or you can use digit cards) to make different totals.

They have got the 2, 3, 4 and 8 bugs.  They have made two totals already and are wondering how many more they can make.

What totals can you make? Which bugs are you using?

How are you going to record what you have done? With a drawing? With a number sentence?

Can you make these totals:

9

10

11

13

14

15

How will you know when you have found all the possible totals?

Can you record your work in a systematic way?

What if…………

…………you choose a different 4 bugs / numbers and do the same thing?
