=== Activity 1: Area and Perimeter concepts ===
=== Materials: ===
Rectangular dot sheets, stationery
=== Objective: ===
To understand the relationship between area and perimeter of 2D shapes
=== Process: ===
# Recall area and perimeter concepts: ask students to explain the meaning of area and perimeter in their own words
# Establish differences between area and perimeter:
#* Perimeter is a one dimensional quantity and area is a two dimensional quantity
#* Area is expressed in sq.units and perimeter in units
#* Area defines the space occupied by a shape, perimeter is the length of its boundary
# Hand over dot sheets to individual students or pairs of students and inform that the distance between any two horizontally or vertically adjacent dots in the dot sheet is 1 cm
# Ask students to draw and shade a square of area 1 sq. cm and ask them to find out the perimeter of the same
# Repeat for 4 sq.cm
# Ask students to observe these shapes and find out what is the area and perimeter of each shape.
