The 7-piece Tangram can be a paper cut-out variety or this Scratch coded version. The Cat sprite gives the instructions (1) Move and rotate the tangram sprite-pieces to make shapes (a to h).(2) Click the black cat to spread out the pieces and reveal the red rotate left and right arrows. (3) Click any letter from a - h to see the grey shape you have to make. See the list below (4) Drag / Select the sprite-piece to move/ rotate (a yellow dot highlights the active sprite-piece).
These shapes are based on Mathemagic 5 p.29, 30, 63 which has been used in Irish schools since 2002. Make a shirt, a fox, a swan swimming, a swan in flight, a rabbit, a squirrel, a cat and an eagle. You can make many more shapes with the 7-piece tangram.
