LO: To solve a tangram puzzle using 2D shapes.
Tangrams! In case you didn’t know what they are. A tangram is a puzzle consisting of seven flat polygons, called tans, which are put together to form shapes. The aim of them is to replicate a pattern generally found in a puzzle book using all seven pieces without any overlapping.
Beginning: Display the tangram square shown on the Lesson Presentation Tangram Triangles and discuss how the square has been divided into seven different shapes which can be arranged to make various other shapes. Using the
Tangram Squares Resource Sheet children cut up the tangram puzzle and identify and describe the properties of the seven shapes with somebody at home.
Discuss how the aim of the tangram puzzle is to rearrange the pieces of the square to create new shapes. Using the examples shown on the Lesson Presentation, children explore rearranging their own tangrams shapes into different triangles. Using the PP, introduce the challenge of finding all the different triangles that can be created using any arrangement of up to seven of the tangram shapes. (Try for at least 3, there are 12 in total)
Help if needed. To give the children a little help use these triangle templates. Some of the shapes have been given as a clue!
If after all that you want to play a game involving 2D shapes then click the link below to play Tetris. The aim of the game is to manipulate the 2D shapes so you can create a full line. Your parents will know this ‘retro’game!
