This is a puzzle I created for my students to do during independent guided math centers. It challenged even my higher students, because you have to know the categories of length, mass, and capacity, but also which conversions are correct and match each other. Through a program my district purchased, I have seen puzzles similar to this, and wanted to create one for this standard!
You would need to print the puzzle on card stock, laminate, and then cut apart the pieces. For easy checking, the puzzle will spell "inch" diagonally from left to right when turned vertically. Great resource to use again and again!
