AREA AND PERIMETER OF PLANE SHAPES LESSON NOTE AND LESSON PLAN FOR PRIMARY, SECONDARY AND HIGH INSTITUTIONS




W.A.L.A: AREA AND PERIMETER OF PLANE SHAPES 



Monday 
 Area  of rectangles and squares
Resources 


Content 
The area of any given shape is the measure of the extent of a surface. Area is measured in square units.
The perimeter of any given shape is the sum of the distance of all the lengths of the sides of that shape.

Examples: 
Find the area of a rectangle whose length is 6cm and width 4cm.

A rectangle is 10m long and 7m wide. What is the area?
Solution 
Area = L X B
        = 6cm X 4cm 
        = 24 cm²
Area = L X B
         = 10 m X 7 m
         = 70 m²

Area of Square
 Area of square = L²  or S². where L= length and S = sides

Examples: Calculate the area of these squares with the following sides. 
7 cm 
 9 m
Solution 
Area = L² 
         = 7cm X 7cm 
         = 49cm²
Area = S²
             = 9m  X 9m
                     = 81m²

Pupils should be Able to ;
Find the area rectangles and squares 

Begin the lesson by asking the pupils to measure the length and breadth of the squares and rectangles  


Tuesday
  Area of triangle 

The formula for finding area of triangle is 1/2 b x h. Where b is base and h is height of the triangle. 


Examples : find the area of the following triangles.
         
Find the area of a triangle with base of 12m and height of 9 m.
Solution 
Area = 1/2 bh
         =   1/2 X b X h
         =   1/2 X 8cm X 6 cm
          = 24cm²

Area of Circle
Area = 1/2  bh
         =   X b X h
         =   X 12cm X 9 cm
          = 54cm 2

Pupils should be Able to
 Find the area of triangle  

Begin the lesson by asking them to;
 identify a triangle 
Then tell them to measure the shapes in centimetres and meters.  


Wednesday
Perimeter of squares and rectangles 



Examples : find the perimeter of these shapes.
A rectangle with length of 8cm and breadth of 5cm.
A square of sides 9m each.
Solution 
Perimeter= L+ B + L + B 
                 = 8cm + 5cm + 8cm + 5cm
                  =26cm 
 OR Perimeter =  2 ( L+ B )
                        = 2 ( 8cm + 5cm)
                         = 2 X 13cm
                          = 26cm
Perimeter of square  = L + L + L + L 
                  =  9m + 9m + 9m +9m 
                   = 36m
OR       Perimeter of square= 4 L
                             = 4 X 9m
                             = 36m

Pupils should be Able to ;
 State the formulae for finding perimeter of rectangle and square        
Begin the lesson by measuring the length of the shapes to be used. 




Thursday 
Perimeter of triangles 


EXAMPLES: find the perimeter of the following shapes with sides :6cm            9cm             5m


     and        8cm             4m          7m
Solution 
Perimeter = 6cm + 9cm + 8cm
                 = 23cm

Perimeter =  5m + 4m + 7m + 6 m
                  =22m


Pupils should be Able to ; calculate the perimeter of any given shapes

Begin the lesson by measuring the sides of the various shapes given.

DISCOUNT AND COMMISSION MATHEMATICS LESSON PLAN AND LESSON NOTE FOR PRIMARY AND SECONDARY SCHOOLS

Monday   Meaning of Discount  Finding cost and cash price on discounted goods Resources  Inside out  Learn   mathematics Book 6, page  125  items like; currency note Milo, biscuits, books, pencils, school bag   Meaning of Discount Discount is a reduction in the price of an article. It is often a certain percentage of the actual price of the article. Examples 1. A table clock cost $200, and a 10% discount is given for paying cash. What is the cash price?

DO YOU SEE THESE STRANGE LINES ON YOUR NAILS? DON'T JOKE WITH IT, THIS IS WHAT IT SAYS OF YOUR HEALTH

As I’ve gotten older, those vertical ridges on my nails seem to be getting more and more prominent. That’s when I decided to do some research to see if those ridges meant anything about my health, and if there was anything I could do to get rid of them. What They Mean About Your Health After a lot of research, I did find that there is a small, rare possibility that those ridges can mean an underlying medical condition or possibly even nail trauma. But for most of us, it’s completely normal as we age to see them getting more noticeable, especially if you have dry skin or skin conditions such as eczema. I’m 36, and they’ve only recently started bothering me, but I’m relieved to find that they are most likely harmless. I’m just getting old. But Why Are They There?
