2. copyright@Ed2netLearning,Inc2 Hello, How are you doing? Today we are going to begin new lesson on Division.

3. copyright@Ed2netLearning,Inc3 Related Facts Basic facts using the same numbers. Example: All of these represents a fact family 7 x 3 = 21 3 x 7 = 21 21 ÷ 3 = 7 21 ÷ 7 = 3

4. copyright@Ed2netLearning,Inc4 Do all of these represent a fact family. 6 x 4 = 244 x 6 = 24 24 ÷ 6 = 424 ÷ 4 = 6 Answer – Yes, all of these represents a fact family.

5. copyright@Ed2netLearning,Inc5 Dividing by 6 Repeated Subtraction – Subtract 6 from the given Quotient till 0 is obtained. Example: 24 ÷ 6 24 – 6 = 18 18 – 6 = 12 12 – 6 = 6 6 – 6 = 0 Thus 24 ÷ 6 = 4

6. copyright@Ed2netLearning,Inc6 Important Tip If a number is divided by 3, and then divided by 2, that is same as dividing by 6. Example – Dividing by 6, 36 ÷ 6 = 6 Dividing by 3 and then by 2 Dividing by 3, 36 ÷ 3 = 12 Then, Dividing by 2, 12 ÷ 2 = 6 Result is same in both cases.

7. copyright@Ed2netLearning,Inc7 Use Division Fact Use Division Facts for 3 and 2- The quotient is twice the size in division facts by 3 as they are for division facts by 6. Example – 12 ÷ 6 = 2 12 ÷ 3 = 4

8. copyright@Ed2netLearning,Inc8 Dividing by 7 Repeated Subtraction – Subtract 7 from the given Quotient till 0 is obtained. Example: 28 ÷ 7 28 – 7 = 14 14 – 7 = 7 7 – 7 = 0 Thus, 28 ÷ 7 = 4

9. copyright@Ed2netLearning,Inc9 Skip Counting (Dividing by 6 and 7) Skip Counting - The number of arcs above the number line gives the Quotient. Example : 30 ÷ 6 0 6 12 18 24 30 Thus, 30 ÷ 6 = 5

10. copyright@Ed2netLearning,Inc10 Related multiplication fact (Dividing by 6 and 7) In related multiplication fact the unknown variable can be found by division. Example – Find the value of ε in the given equation 7 x ε = 56 The ε stands for the number that is multiplied by 7 to get 56. Thus, ε = 8

11. copyright@Ed2netLearning,Inc11 Find the quotient of 49 ÷ 7 using repeated subtraction Answer- 49 – 7 = 42 42 – 7 = 35 35 – 7 = 28 28 – 7 = 21 21 – 7 = 14 14 – 7 = 7 7 – 7 = 0 Thus, answer- 7
