1. CLASS : V TOPIC : PERIMETER Time required : 6-8 periods

2. Learning Objective : To find the Perimeter of a Square – Rectangle – Triangle -

3. Teaching Learning Materials Used Lollipop Sticks- Thread – Paper squares - Square ruled sheets-

4. Mathematical Vocabulary & Symbols Closed figure, Open figure, Plane figure, Side, Edge, Boundary, Length,Total, Sum, Perimeter Units of length - cm, m, mm, km Symbol Used : +

5. Concept : Perimeter Perimeter is the length of the boundary of a plane figure. Perimeter is the distance around the outside edge of a plane figure. To find the Perimeter, we add the length of all sides of a plane figure.

6. Pupil Activity-1 Building with sticks Triangles - Rectangles - Squares -

7. Pupil Activity-2 Finding the total length of the sticks and giving the perimeter of the figures formed by them. 4 cm 2 cm

8. 1 cm Perimeter = (1+1+1+1)cm = 4cm Pupil Activity -3 Finding the Perimeter of the figure on a square sheet.

9. Pupil Activity -4 Finding the Perimeter of the figure on a square sheet. Perimeter =(4+4+4+4)cm = 16cm 4 cm

10. Pupil Activity -5 FIND THE PERIMETER OF THIS TRIANGLE USING A THREAD AND A MEASURING SCALE

11. EVALUATION (HOME WORK)

12. FIND THE PERIMETER OF THIS SURFACE IF ONE SIDE OF A SQUARE IS EQUAL TO 1 cm. HINT : COUNT THE NUMBER OF SIDES. Perimeter = ________ cm

13. FIND THE PERIMETER OF THIS SURFACE IF ONE SIDE OF A SQUARE IS EQUAL TO 1 foot. HINT : COUNT THE NUMBER OF SIDES. Perimeter = ________ feet

14. EVALUATION (PROJECT)

15. SOLVE THIS PROBLEM TWO NEIGHBORS BUILD SWIMMING POOLS. THIS IS WHAT THE POOLS LOOK LIKE. Family A Family B WHICH FAMILY HAS MORE SIDE PANELS OF THE POOL TO CLEAN?
