Divide by 2

Key Notes :

Definition of Division:

Division is splitting a number into equal parts. When dividing by 2, you are splitting the number into two equal groups.

Basic Concept of Dividing by 2:

• Any number divided by 2 gives half of that number.
• Example: 6 ÷ 2 = 3.

Using Objects for Understanding:

• Use counters, blocks, or pictures to demonstrate how to divide groups evenly.
• Example: Place 8 blocks in two equal groups to show that 8 ÷ 2 = 4.

Even and Odd Numbers:

• Even numbers can be divided by 2 evenly without remainders.
• Odd numbers will leave a remainder when divided by 2.
• Example: 9 ÷ 2 = 4 remainder 1.

Relation to Halves:

Dividing a number by 2 is finding “half” of that number.

• Example: Half of 10 is 5, so 10 ÷ 2 = 5.

Real-Life Examples:

• Sharing candy equally between two friends.
• Splitting a pizza into two equal parts.

Number Patterns:

• Recognize patterns when dividing by 2, such as all results (quotients) being whole numbers for even inputs.

Word Problems:

• Incorporate simple story-based problems to make learning relatable.
• Example: “If you have 12 apples and you want to share them equally between 2 baskets, how many apples will be in each basket?”

Remember how to divide by 2:

2 ÷ 2 = 1
4 ÷ 2 = 2
6 ÷ 2 = 3
8 ÷ 2 = 4
10 ÷ 2 = 5
12 ÷ 2 = 6
14 ÷ 2 = 7
16 ÷ 2 = 8
18 ÷ 2 = 9
20 ÷ 2 = 10
