Activities

[Contributor - Stuti Shah]

1. Ask students to form groups of 4. They can then find the mean, median and mode of:

Their height
Their weight
Also represent the same graphically through a bar graph and histogram.

2. Ask students if they want to buy a ball, which colour would they prefer it to be. Ask students to colour a piece of paper either of these 5 colours: blue, green, yellow, red, white to indicate their choice. After the number of children who selected each number is added up, ask each student to represent each colour choice graphically through a bar graph and histogram.
