TanFree

Tangrams Free allows students to solve tangrams. The student starts with a silhouette and seven pieces. The pieces can be rotated, flipped, and translated; the goal is to replicate the silhouette using all seven pieces. This is a great virtual manipulative because unlike physical manipulatives, this program allows students to ask for hints in solving the tangram. If a hint is requested, the program will show the correct location of the selected piece. The student can then continue solving the puzzle. This is an excellent activity for students of varying ability levels.
