 Class 07 Group Activity

Objective: 

To gather information about  preference for some particular soft drinks among the Students of a class and draw a bar graph.

Materials Required: 

Graph paper, pencil, ruler.

1.The students go around and ask each of their classmates, which soft drink they like most.. Accordingly, a tally mark is put at the column of that soft drink.

2. The students count the preference for each soft drink and enter the value in the frequency column.

3. Now, the students take a graph paper each, and draw the x-axis (horizontal axis) at the bottom of the paper and y-axis (vertical axis) at the left side of the paper. The point of intersection is marked as O. Let the x-axis represent the soft drinks and the y-axis the number of students. Here, each sq cm represents one child.

4. Then they draw the bar graph. Also, they must calculate the fraction, decimal, and percentage for each soft drink.
