                   Sphere: The figure given below is a sphere.                    Some spherical objects are

                                            •  A sphere has one curved  shown below.

                                                face.
                                            •  It does not have any edge

                                                or vertex.

                        activity
                   touch and tell. Who am I?
                   Place different wooden solid  shapes  or objects with  variation  in

                   faces,  corners  and  edges.  Blindfold  a  child  and  ask  them  to pick
                   an object as per the details given by other children.
                   For example, a student may be asked to take out an object with
                   one corner.
                   Similarly, continue with other objects with another student.

                           Think and Answer
                        Name the objects which have:

                        1.  no corners      2.  1 corner        3.  2 edges         4.  6 faces

                  1.  Look at your surroundings and name:

                       (a)  one cubical object.              _______  (b)  one spherical object.  _______

                       (c)  one cylindrical object.          _______  (d)  one cuboidal object.               _______

                  2.  How many faces, vertices and edges do these solid shape have?

                          Solid shape           Cube          Cuboid           Cone          Cylinder         Sphere

                              Faces

                            Vertices

                             edges
