                  Objective: To reinforce the concept of subtraction in a play way

                  method.

                  Materials Required: Empty shoe box, paint colour, brush, paper
                  cutter, some tennis balls, number cards and a toy hammer.

                  Preparation:

                          Take an empty shoe box with a lid.

                          Cut out 10 circles in the lid as shown in the image.
                          Make sure that the size of the circle is slightly

                          smaller than the circumference of the tennis balls.

                          Prepare some cards with subtraction problems
                          within 10.

                          Paint the shoe box in bright colours to make it look attractive.

                          Jumble the cards and place upside down on a table.
                  Procedure:                              Whack a Ball

                          Invite the students in small groups for the activity.
                          A student will pick a card and solve it. For example, if the card says 8  – 3, the

                          student will count and place 8 balls in the 8 circular slots.

                          To subtract 3, the student will whack three balls with a toy hammer so that
                          the balls that are hit, drop into the  box.

                          To find the answer of 8  – 3, the student will count the number of remaining

                          balls, that is 5.

                          Similarly, other students follow the steps by choosing other cards.

                          Continue the activity till time permits.
