Content:

1. Definition and Explanation of Division:

• Division is the process of splitting a number (dividend) into equal parts (quotient).
• A dividend is the number being divided.
• A divisor is the number by which the dividend is divided.
• The quotient is the result of the division.
• Sometimes, division results in a remainder, which is the part left after dividing.

Examples:

1. 24 ÷ 6 = 4
   (Dividing 24 into 6 equal parts gives 4 in each part)
2. 36 ÷ 9 = 4
   (36 items shared equally among 9 people gives 4 items per person)
3. 56 ÷ 7 = 8
   (56 apples shared equally among 7 friends gives 8 apples each)
4. 63 ÷ 3 = 21
   (63 books divided by 3 people gives 21 books each)
5. 72 ÷ 8 = 9
   (72 candies shared among 8 friends gives 9 candies each)

Class Activity Discussion (15 FAQs with answers):

1. What is division?
   Division is splitting a number into equal parts.
2. What do we call the number we are dividing?
   The number we are dividing is called the dividend.
3. What do we call the number by which we divide?
   The number we divide by is called the divisor.
4. What is the result of division called?
   The result is called the quotient.
5. Can division leave a remainder?
