Learning by Doing
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.
