Multiplication facts for 6, 7, 8, 9: sorting
Key notes :-
1. Understanding Multiplication Facts:
- Multiplication is repeated addition. It helps in finding the total when a number is added several times.
- For example: 6×4 means adding 6 four times (6 + 6 + 6 + 6).
2. Multiplication Tables for 6, 7, 8, and 9:
- Multiplication of 6:
- 6 × 1 = 6, 6 × 2 = 12, 6 × 3 = 18, 6 × 4 = 24, etc.
- Multiplication of 7:
- 7 × 1 = 7, 7 × 2 = 14, 7 × 3 = 21, 7 × 4 = 28, etc.
- Multiplication of 8:
- 8 × 1 = 8, 8 × 2 = 16, 8 × 3 = 24, 8 × 4 = 32, etc.
- Multiplication of 9:
- 9 × 1 = 9, 9 × 2 = 18, 9 × 3 = 27, 9 × 4 = 36, etc.
3. Sorting Multiplication Facts:
- By Result: Arrange multiplication facts by their product (answer).
- Example:
- 6 × 3 = 18, 8 × 2 = 16, 9 × 4 = 36. Sorting: 16, 18, 36.
- Example:
- By Numbers Involved: Sort by one of the factors (e.g., only group all the facts involving 7).
- Example:
- 7 × 2, 7 × 5, 7 × 3.
- Example:
- Smallest to Largest Product: Arrange the results in ascending order (small to large).
- Example: 6 × 1 = 6, 7 × 1 = 7, 8 × 2 = 16, 9 × 3 = 27.
Learn with an example
Multiply to find the products. Is each product less than 36, equal to 36, or greater than 36?
Place each expression into the correct box.
- 7 x 5
- 9 x 2
- 9 x 5
Look at one expression at a time.
Multiply to find the product of each expression. Then, compare the product to 36.
7 × 5
The expression 7 × 5 means 7 groups of 5.
5 + 5 + 5 + 5 + 5 + 5 + 5 = 35
7 × 5 = 35
7 × 5 belongs in the less than 36 box.
9 × 2
The expression 9 × 2 means 9 groups of 2.
2 + 2 + 2 + 2 + 2 + 2 + 2 + 2 + 2 = 18
9 × 2 = 18
9 × 2 belongs in the less than 36 box.
9 × 5
The expression 9 × 5 means 9 groups of 5.
5 + 5 + 5 + 5 + 5 + 5 + 5 + 5 + 5 = 45
9 × 5 = 45
9 × 5 belongs in the greater than 36 box.
Place each expression into the correct box.
Multiply to find the products. Is each product less than 15, equal to 15, or greater than 15?
Place each expression into the correct box.
- 9 x 1
- 9 x 2
- 7 x 2
Look at one expression at a time.
Multiply to find the product of each expression. Then, compare the product to 15.
9 × 1
The expression 9 × 1 means 9 groups of 1.
1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 = 9
9 × 1 = 9
9 × 1 belongs in the less than 15 box.
9 × 2
The expression 9 × 2 means 9 groups of 2.
2 + 2 + 2 + 2 + 2 + 2 + 2 + 2 + 2 = 18
9 × 2 = 18
9 × 2 belongs in the greater than 15 box.
7 × 2
The expression 7 × 2 means 7 groups of 2.
2 + 2 + 2 + 2 + 2 + 2 + 2 = 14
7 × 2 = 14
7 × 2 belongs in the less than 15 box.
Multiply to find the products. Is each product less than 20, equal to 20, or greater than 20?
Place each expression into the correct box.
- 7 x 2
- 9 x 2
- 8 x3
Look at one expression at a time.
Multiply to find the product of each expression. Then, compare the product to 20.
7 × 2
The expression 7 × 2 means 7 groups of 2.
2 + 2 + 2 + 2 + 2 + 2 + 2 = 14
7 × 2 = 14
7 × 2 belongs in the less than 20 box.
9 × 2
The expression 9 × 2 means 9 groups of 2.
2 + 2 + 2 + 2 + 2 + 2 + 2 + 2 + 2 = 18
9 × 2 = 18
9 × 2 belongs in the less than 20 box.
8 × 3
The expression 8 × 3 means 8 groups of 3.
3 + 3 + 3 + 3 + 3 + 3 + 3 + 3 = 24
