DIVIDING BY 6 & 7

Grade3


Hello, How are you doing?Today we are going to begin new lesson on

Division.


Related FactsBasic 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


Do all of these represent a fact family. 6 x 4 = 24 4 x 6 = 2424 ÷ 6 = 4 24 ÷ 4 = 6

Answer – Yes, all of these represents a fact family.


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 = 0Thus 24 ÷ 6 = 4


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 2Dividing by 3, 36 ÷ 3 = 12Then, Dividing by 2, 12 ÷ 2 = 6Result is same in both cases.


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


Dividing by 7• Repeated Subtraction – Subtract 7 from

the given Quotient till 0 is obtained.Example: 28 ÷ 728 – 7 = 1414 – 7 = 77 – 7 = 0

Thus, 28 ÷ 7 = 4


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


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 = 56The ε stands for the number that is multiplied

by 7 to get 56.Thus, ε = 8


Find the quotient of 49 ÷ 7 using repeated subtractionAnswer-49 – 7 = 4242 – 7 = 3535 – 7 = 2828 – 7 = 2121 – 7 = 1414 – 7 = 7 7 – 7 = 0Thus, answer- 7
