In this Tarsia puzzle, students solve the equation on the edge of a small triangle and match it with the answer on the edge of another small triangle. When completed, all the pieces will form a large triangle.
This puzzle contains 18 fraction addition equations. Equations have unlike denominators, and most answers are greater than one. Many of the answers must be simplified.
I've included the completed triangle (which can be used for the key), as well as the 18 pieces and a table of all the equations and corresponding answers. The pieces will need to be cut and (probably) laminated.
My students love these puzzles, and I love that they are naturally self-checking. If students don't see their answer, they know they need to solve the equation again.
