Lesson 1: The meaning of the division operation .

Example "1" :



‐ 51 ‐



‐ 52 ‐

* If we distribute divide the pencils equally among Ahmed and Mona

to give each one the same number of pencils .

* Each one takes 3 pencils .

So , we write this as :

6 = 3 x 2



‐ 53 ‐

• 30 flowers are given equally to Mohamed , Omar and Ahmed .

Each one takes …………… flowers

So , 30 ………… x 3

Example "2" :



‐ 55 ‐

If we distribute divide 9 apples among Omar and Ahmed , such that each one

takes the same number of apples .



‐ 56 ‐

* Omar takes 4 apples * Ahmed takes 4 apples .

, and there will be 1 apple remainder.

So, we write this as :

9 = ( 4 x 2 ) + 1

Complete :



‐ 57 ‐

A If we divide 23 pencils equally among three boys ,then the greatest

number of pencils each one takes …………… and the number

of remaining pencils ……………… pencils .

Then : 23 ………… x 3 ………………

Using the Division Sign ( ÷ )



‐ 60 ‐

In the previous pictures, there are 6 butterflies, and in each group there are 3

butterflies.

So, the number of groups 6 ÷ 3 2 groups .

This operation is called " Division "



‐ 61 ‐

So, we read: 6 ÷3 2 as : Fifteen divided by five equals three .

Remark:

If you see some words like:

* Distributed ……………… among …………………



‐ 62 ‐

* Divide ………………… by ……………………

* How many sets groups of ……………… are there in ……………… ?

* How many ……………………… are there in …………………… ?

They usually means that you should divide the two numbers .

• The length of its third side = ...................................................... metres.

5) The perimeter of any geometrical shape = ………….……….. of side lengths.

Lesson 2:

The perimeter of the square and the rectangle

Rectangle Square

In the rectangle every twoopposite sides are equals in length

The perimeter of a rectangle=Length + width + length + width

OR ( length + width ) x 2

Perimeter = 4 + 3 + 4 + 3 = 12 units.OR = ( 4 + 3 ) x 2 = 12 units.

Dimensions means: length and width

In the square four sides areequals in length.

The perimeter of a square=Length + length + length + length

OR side length x 4

Perimeter = 3 + 3 + 3 + 3 = 12 units.OR = 3 x 4 = 12 units..
