Tarsia is one of the best educational resources that keep pupils and adults engaged and excited about a lesson.
This app allows you to customize the size of the puzzles and the geometric shape, depending on the number of keywords you want to use.
You can email the puzzles to a fellow educator, print, them or you can save it in your bank of resources for later use.
Tarsia puzzles can be used as a matching activity, where the triangles are printed on paper or cardboard, cut out, and mixed up. Then they need to be given to the learners, who will try to create the initial shape by placing the keywords together.
