# Year 2 maths worksheet: Addition investigation

Here we have a maths investigation on addition, suitable for year 2. There are four numbers shown. The task is to choose any three numbers and add them up. Each number can be used up to 3 times, but the total sum must not include more than 3 numbers. So the sum could be 2 + 2 + 2, or 2 + 4 + 4 etc.

How many different ways are there of doing this and how many different answers are there.

These mini investigations are all about logical thinking, trying things out, working in a systematic way, recording information and checking that results have not been duplicated. They should also be fun. Most young children will not work in a systematic way, will repeat results and miss results – that is to be expected. But, over time they should begin to develop these skills. This investigation is good at encouraging working in a methodical way, starting with the smallest numbers, or starting with the largest numbers.
