When it was put together it made a large triangle. We found out that there is more than one solution to make the large triangle work. Students had to figure out the subtraction problem and also figure out how to make it work to form a large triangle and complete the puzzle. This allowed for A LOT of great conversations!

It was probably one of the many things I have pinned from Pinterest. For this puzzle, students had to match up the subtraction equations with their answers. One triangle had equations and another had answers.
