Multiplication Using Visual Models (Part 1)

The video tutorial explains multiplication as repeated addition and introduces the commutative property, which states that the order of numbers does not affect the product. It demonstrates using rectangular arrays to visualize multiplication, providing examples with 7 times 3 and 4 times 6, showing how to construct arrays and count the total points to find the product.

What does the commutative property of multiplication state?

• Multiplication is not related to addition.

• The product is always greater than the sum.

• The product remains the same regardless of the order of numbers.

• The product changes when the order of numbers changes.

How can you represent the multiplication of 7 and 3 using arrays?

• By drawing 7 rows and 7 columns.

• By drawing 3 rows and 3 columns.

• By drawing 3 rows and 7 columns.

• By drawing 7 rows and 3 columns.

What is the total number of points in the array for 7 times 3?

• 21

• 20

• 19

• 18

How many rows and columns are needed to find the product of 4 and 6 using arrays?

• 6 rows and 6 columns

• 6 rows and 4 columns

• 4 rows and 4 columns

• 4 rows and 6 columns

What is the result of multiplying 4 by 6 using arrays?

• 26

• 24

• 22

• 20
