The tangram is a Chinese puzzle with seven geometric pieces that fit together to make a square. No one is really certain as to who first created this puzzle but the earliest book of tangram puzzles was published in China in 1813. The seven pieces can be rearranged to create many patterns.
Our class looked closely at tangrams at the end of third term. We used a table to record our observations about creating 2D shapes with the tangram puzzle pieces. We tried to make a square, triangle and a rectangle using 1, 2, 3 or 4 puzzle pieces. For some of these challenges there was more than one way to create the shape.
We measured the edges of our puzzle pieces and compared the different measurements. From these measurements we were able to calculate the perimeter of each shape.
Last of all we created some shapes with our puzzle pieces for others to have a go at making.
