                  Objective: Understanding the numbers up to 50.
                  Materials Required: Matchsticks and rubber bands

                  Procedure:

                          The teacher divides the class into 4 groups.
                          Distribute 20 matchsticks and 2 rubber bands to each group.

                          Ask each group to make 2 bundles of 10 matchsticks.

                          Collect the bundles from the groups.

                          Call one group. Give them the bundles of tens and some loose matchsticks.
                          Ask them to make two numbers say, 26 and 27.

                          Check how they work.

                          You can also ask them to compare the two numbers.

                          Repeat the activity with other groups with different numbers.

                       1.   I am a 2-digit  number. My ones place  has  the  greatest            tens Ones
                           digit. My tens digit is 5 less than the ones digit. Who am I?

                       2.   I am a 2-digit number. The number of fingers in your one             tens Ones
                           hand  gives my ones digit.  The number  of  eyes that you
                           have gives my tens digit. Who am I?
