Percentage %

The students were tuned in to the concept of percentage where they first looked at the meanings of the terms, cent, centenarian, century, centurion. They understood that each word focused on something out of 100. 

They were then tuned in to the concept where they colored different portions of a graph paper out of 100 and reached to an understanding that percentage is out of 100.
They also practised converting simple percentage into fractions and decimals and vice versa.
