ii)compare and identify the same sum.
iii)classify the cards having the same sum.
iv)conclude that a number can be obtained in many ways.

Instruction to teachers

l     Write all possible ways of obtaining a number by adding any two addends on the cards

          For example: The number nine (9) can be obtained by a combination of different numbers as shown below

1 + 8

     2 + 7 

 3 + 6

4 + 5

   9 + 0

l     Do this for numbers 1 to 8

l     Next, spread all the cards on the table or floor

l     Ask the students to find the sum of the numbers on each card

          Help them to group the cards having the same sum.

          Initiate a discussion by asking questions of the following type (for all numbers)

   i)     In how many ways can you get the number 8?

  ii)     Which are they?

          Help them conclude that a number can be obtained in many ways.

        Extension: If the topic ‘subtraction’ has been completed, you can add cards which indicate different combinations by which a number can be expressed (by subtraction)

For example, the number 6 (six)

  10 – 4     9 – 3

8 – 2

7 – 1

 6 – 0
