Division of whole numbers

Lesson Note: Division of Whole Numbers using Distributive Rule

Topic: Division of Whole Numbers Class: Basic 3 Curriculum: Hybrid

Introduction to Division: Division is a way of sharing or grouping objects into equal parts. It is represented by the symbol ÷.

What is Division? Division helps us find out how many groups we can make from a certain number of items. For example, 12 ÷ 4 = 3 means we can make 4 groups with 3 items in each group.

Distributive Rule: The distributive rule helps us divide when we have addition or subtraction. The rules are:

• a ÷ (b + c) = a ÷ b + a ÷ c
• a ÷ (b - c) = a ÷ b - a ÷ c

Examples:

1. Sharing Toys: Tom has 18 toys to share among 3 friends. How many toys per friend?

   • Solution: 18 ÷ 3 = 6 toys per friend

2. Dividing Fruits: A vendor has 24 apples to pack into bags of 4 apples each. How many bags?

   • Solution: 24 ÷ 4 = 6 bags

3. Grouping Students: A teacher has 20 students to divide into groups of 5. How many groups?

   • Solution: 20 ÷ 5 = 4 groups

Class Work:

1. 15 ÷ 3 = ?
2. 24 ÷ 6 = ?
3. 9 ÷ 3 = ?

Assignment:

1. A bookshelf can hold 4 rows of books. If there are 24 books, how many per row?
2. A bakery has 36 cupcakes to package in boxes of 6. How many boxes?
3. If 48 pieces of candy are shared equally among 8 friends, how many pieces per friend?

Remember: Practice division to understand it better and use it in everyday life.
