                   Objective: Wrapping and decorating a gift box.

                   Materials Required: An empty shoebox or any other cubical/cuboidal box, a sheet

                   of gift wrapping paper, some star cutouts, colourful ribbon/paper strips, some
                   decorating stones and glue.

                   Procedure:

                          First, cover the box with a wrapping paper.

                          The part of the box that we see or touch is its surface or
                          face. Paste a star on each face of the box.

                             How many stars have you used? ________
                          The line where two faces of the box meet is called the edge.
                          Glue the colourful strips and put it along all its edges.

                             Are the lengths of all the strips the same? ________

                             How many strips have you used in all? ________
                          The meeting point of the edges is called a corner or vertex.
                          (The plural of vertex is vertices.) Fix a decorating stone on each

                          of the vertices.

                             How many decorating stones have you used in all? ________

                          Wow! Your gift box is so beautiful.

                             Thus, you observe that a cuboid/cube has ________ faces,
                             ________ edges and ________ vertices.

                                                                                                                 Logical Thinking
                                                                                                       Creative Thinking
                          Challenge Question
                     1.  Using the dots shown here, how many rectangles can you create?
                         [Hint: A square is also a type of rectangle.]

                     2.  Look at the pattern carefully and figure out the missing number.
