puzzle pyramids

our teacher had a task on  the contract with a pyramid made of circles the only thing she could tell us about was that it is addition and that it was a puzzle. it was a bit confusing until i started adding the starting numbers in the circles then it increased the amount of numbers which means more to add then eventually i would fill all the pyramid.

we had to do this 3 times and it was kind of fun when i got the hang of it.  the pyramids were confusing because there were only numbers in it. but then i got it and i cant wait for more.
