Instructions to teachers:
Draw a table with ten rows and ten columns on the blackboard. Fill up the boxes with fractions, decimals and percents as shown below. However, to start with, smaller tables i.e. 5 ´ 5 or 4 ´ 4 may be considered.
Group Activity:
Give the illustration shown below and ask the students find out as many combinations as possible
(That is, a fraction, a decimal, a percent) that total up to 100%.
For example, 0.15 + 60% + = 15% + 60% + 25% = 100%

(Fill up the remaining seven rows and ten colomns in the same way.)
Individual activity:
Ask each child to write a 10 ´ 10 table in his / her book with different fractions, decimals and percents, and find out as many combinations as possible, which total to 100%. The one who does more number of such conversions is the winner. To make the activity a little competitive, set a time limit.
