Activity: Hands-on activity

An activity was conducted for the students where they were asked to use Bindis of 2 different
colors on a grid of numbers from 1 to 50 drawn on a paper. The children were asked to find the
factors of 10 and 20. The children used one color Bindi for the factors of 10 and the other for
factors of 20. The children observed that few numbers had both the colors of Bindis and
concluded that these were the Common Factors. The highest number among the Common
Factors was the Highest Common Factor (HCF). The students enjoyed the activity and

understood the Concept of Highest Common Factor easily.
