Lesson: What is Divison

Division is a way of splitting a number into equal parts. It helps us figure out how many equal groups we can make or how many items each group will have.

Basic Concepts of Division

Division is the opposite of multiplication. In division, we start with a big number and split it into smaller equal groups. Division problems use the ÷ symbol.

Example: 12 ÷ 3 = 4. This means 12 items are divided into 3 equal groups, with 4 in each group.

Division with Remainders

Sometimes, when we divide, we don’t get a perfect number of items in each group. The leftover items are called remainders.

Example: 10 ÷ 3 = 3 R1. This means 10 items are divided into 3 groups, with 1 item left over (the remainder is 1).

Understanding Division

Division can be understood as sharing or grouping. If you have a total number and want to share it equally among friends or divide items into groups, you use division.

Example: You have 15 candies and want to share them with 5 friends. How many candies will each friend get?
15 ÷ 5 = 3. Each friend gets 3 candies.

Basic Division

To solve basic division problems, start by figuring out how many groups or items per group there are.

Example: 20 ÷ 4 = 5
This means 20 items are split into 4 equal groups, and there are 5 items in each group.
Example: 30 ÷ 6 = 5
This means 30 items are divided into 6 equal groups, with 5 in each group.

Advanced Division

In more advanced division, you may divide larger numbers or encounter remainders more often. Practice with bigger numbers can help build confidence.

Example: 45 ÷ 5 = 9
This means 45 items are divided into 5 equal groups, and each group has 9 items.
Example: 22 ÷ 4 = 5 R2
This means 22 items are divided into 4 groups, with 5 in each group and a remainder of 2.
