              Objective: To form different shapes by joining the pieces of a Tangram.

              materials required: Card paper, scale, pencil, a pair of scissors.

              Procedure:


                     Š Take a piece of card paper and cut a square of size 8 cm by 8 cm from

                      it.

                     Š Draw three horizontal lines and three vertical lines on it at equal gaps

                      with the help of a pencil and scale, so that 16 small squares are
                      formed inside the big square.


                     Š Draw one complete diagonal and one incomplete diagonal of a big

                      square, as shown here. Then draw one square and one triangle using

                      these diagonals (shown in red colour). Extend one side of square as
                      shown here.


                     Š Cut the big square into 7 pieces (tans), as shown below. You can use
                                                                                                          3       4
                      different colours for each piece.                                                        6
                                                                                                            5
                                                                                                         7         2

                                                                                                             1

                     Š Arrange these pieces of the Tangram to form different shapes.
