Square Pairs

Square Pairs

We are exploring square and triangular numbers in math groups this morning.
Using the numbers 1-18 the challenge is to add two of these numbers together but use each number only once. Each answer must also equal a square number.
We found this challenging but fun. Some of us even managed to create square numbers using 1-24 once only.

Could you complete this challenge? If you do what patterns did you discover?
