                       Tangram

                       A tangram is a Chinese puzzle. It has seven pieces.                                          4
                       You can see the tangram shown here.                                                   3   6
                       A tangram is a puzzle that starts as a single square.                                 7  5     2
                         •   Take a piece of thick card paper and cut out a square of size 8 cm                  1
                            by 8 cm from it.
                         •   Draw three horizontal lines and three vertical lines on it at equal             3       4
                            gaps so that 16 small squares are formed inside the big square.                       6
                            Use pencils and a scale for drawing the squares.                                7  5      2
                         •   Draw one complete diagonal and one incomplete diagonal of the                       1
                            big square as shown here. Then draw one square and one triangle
                            using these diagonals (shown by the red colour). Extend one side
                            of the square as shown here.                                                     3    6  4

                         •   Cut the big square into 7 pieces (see below): Two large triangles;                5      2
                            one medium triangle;  two small triangles;  one square  and one                 7
                            parallelogram. You can use different colours for each piece.                         1

                                            1              2            3         4       5       6        7
                         •   Arrange these pieces of the tangram
                            to form different shapes.

                         •   You  can use  these  seven pieces  to
                            make thousands of different shapes,
                            like animals, people, or objects. The
                            goal is to use all seven pieces without
                            overlapping them.
