'''Pre-requisites:'''
 +
 
 +
(a) Knowledge of finding the similarities and difference in the patterns of leaf.
 +
 
 +
The teacher should ask children’s to come up with their own criteria for leaf classification and then ask students to classify based on the criteria given.
 +
 
 +
'''Instructions to do the activity'''
 +
 
 +
   • Divide the class into 3-4 groups of students. Each group should gather a collection of leaves in a basket.
 +
 
 +
   • Bring them to a place where it could be spread and take a close look at them.
 +
 
 +
   • Study the leaves and think of your own ways to sort the leaves into groups. place them in  separate groups on the ground.
 +
 
 +
   • Write a note and place it below each group to say why you have put the leaves together?
 +
 
 +
   •  After children’s classification teacher should ask children’s to sort leaves based on specific criteria’s like shape, size, color, margin and venation.
 +
 
 +
   • Then discuss children’s reasons for each criteria of classification.
 +
