Find the Difference printable sheet

Place the numbers 1 to 6 in the circles so that each number is the difference between the two numbers just below it.

One circle in the top row, two circles in the next row, three circles in the bottom row

For example: The number 3 above the numbers 2 and 5  5 - 2 = 3

You could use this interactivity to try out your ideas:


Can you find more than one solution?

Can you find all the possible solutions? How do you know you have found them all?
