Activities

[Author - Kripa S]

1. Measure length and breadth of your notebook using a scale. Calculate the perimeter and area of your notebook.

2. Repeat the same for your blackboard and find the perimeter, area of your blackboard.

3. How many notebooks can cover the entire blackboard ?

Lesson Plan version 1.1 activites

1. Warm-up Session

Divide the class into four groups. Provide cardboard cut-outs of the following shapes to each group:

Square ,Rectangle ,Triangle ,Hexagon

Ask each group to calculate the length of the boundary of each cut-out. Ask each group to share its answer with the other groups.

Now, tell the students that they have just calculated the perimeter of the cardboard cut outs. Explain the concept of perimeter and then lead into the lesson.

2. Divide the class into three groups. Ask each group to arrange their notebooks to form a rectangle. The

size of geometrical figures can vary from group to group. Ask each group to sketch the inner boundaries of the geometrical figures on a graph paper. Then, ask each group to calculate the perimeter of the rectangles.

3. Divide the class into two groups. Ask the first group to calculate the area of their mathematics

textbook. Ask the second group to calculate the area of the blackboard. Now, ask both groups to find the number of books required to cover the entire blackboard.
