### 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.

1. You can try out the parcc grade 6 mathematics practice test to check yourself up. You can know your limits from different exams. They are providing standard question patterns.

2. In the event that I can compose like you, I would be exceptionally glad, yet where is my karma like this, truly individuals like you are a model for the world.

### NUMERATION AND NUMBER NOTATION LESSON PLAN AND LESSON NOTE FOR PRIMARY, SECONDARY AND HIGH SCHOOLS

Guide Days Content  Starter  Plenary Class Activities Homework  Monday   Counting and writing whole numbers up to 1000.  Counting and writing numbers in units of thousands.  Writing Numbers in Units of thousands in words.  Resources   Beads, Beans, Number chart, match box  Introduction to numeration and notation  Numeration is defined as the act of counting numbers in words or numerals. Example 1 is one, 2 is two, 10 is ten, 100 is one hundred and 1000 is one thousand while notation is the act or system of using symbols to represent numbers. Example 0,1,2,3,4,5,6,7,8,9 and 10 Counting and writing whole numbers up to 1000 Counting and writing whole numbers up to 1000 will be a lot easier if we classify the numbers into three groups: a. 0 - 9 (these are numbers in units)  b. 10 - 99 (these are numbers in tens)  c. 100 - 999 (these are numbers in hundreds)  Example 1 1. Write 5 consecutive numbers after each of these numbers

### 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? Solution The discount = 10% of \$200 =   10     x 200= 20 100 So Cash price = original price – discount                                                             Amount   =    \$200 –  \$20 = \$180  2. The selling price of a shirt is \$900. The trader gives 5% discount for cash. How much is the buyer paying. Solution The discount = 5% of \$900 = \$45 So Cash price = original price – discount amount                         = \$900 – \$45 = \$855 Begin the lesson by showing them an image of a market where buying and selling is taking place, then
