MATHEMATICS LESSON PLAN

Class 5 Maths Lesson Plan

Understand the concept of perimeter as the boundary length and area as the surface covered.
Apply formulas for perimeter and area of square, rectangle, and triangle.
Find unknown dimensions when perimeter or area is given.
Relate area and perimeter in rectangular figures.
Solve real-life word problems involving tiling, fencing, and flooring.

Begin with a short discussion: ask students where they have seen tiles, carpets, or fences — introducing the idea of area and perimeter.
Explain perimeter as the total boundary length of a figure with examples of square, rectangle, and triangle.
Write formulas on the board:
- Perimeter of square = 4 × side
- Perimeter of rectangle = 2 × (length + breadth)
- Perimeter of triangle = sum of all sides
Explain area as the region covered by the figure.
Write formulas for area:
- Area of square = side × side
- Area of rectangle = length × breadth
Discuss problems where either perimeter or area is given and students have to find missing dimensions.
Show examples where both area and perimeter are given to find length and breadth (by forming equations).
Conclude with simple tile-based problems – e.g., how many tiles are needed to cover a floor of given dimensions.
Students do excercise 12A, 12B,12C as cw and HW.

“Mr. Rectangle Forgot His Dimensions”

a story: “Mr. Rectangle forgot his length and breadth but remembers his perimeter and area.”
Students are given the perimeter and area (for example, perimeter = 34m, area = 60 m²).
In groups, students find out the missing length and breadth by reasoning and calculation.
