Finding Factor Pairs with Area Models

The video tutorial explains how to use area models to find factor pairs of numbers. It begins with an introduction to area models and the commutative property of multiplication. The lesson demonstrates finding factor pairs for the number 6, emphasizing the importance of listing a number as a factor of itself. The tutorial then applies the same method to find factor pairs for the number 20, showing how to systematically check possible factors. The lesson concludes by summarizing the process and benefits of using area models for this purpose.

What is the main purpose of using area models in this lesson?

• To subtract numbers

• To divide numbers into equal parts

• To identify factor pairs of a number

• To find the sum of numbers

Which property states that 2 x 3 is the same as 3 x 2?

• Identity Property

• Commutative Property

• Distributive Property

• Associative Property

When finding factor pairs of 6, why is it important to list 6 as a factor of itself?

• Because 6 is a multiple of 3

• Because 6 is a prime number

• Because 6 is an even number

• Because 1 x 6 equals 6

What is the first step in finding factor pairs for the number 6 using rectangular arrays?

• Create an array with 1 row

• Create an array with 4 rows

• Create an array with 3 rows

• Create an array with 2 rows

Which of the following is NOT a factor pair of 20?

• 3 and 7

• 2 and 10

• 4 and 5

• 1 and 20

How many rows can be formed when using an area model for the number 20 with 2 rows?

• 5 rows

• 10 rows

• 20 rows

• 2 rows

Why can't 3 rows be used to form an area model for the number 20?

• Because 3 x 5 is 15

• Because 3 x 4 is 12

• Because 3 x 7 is 21

• Because 3 x 6 is 18

What indicates that all factor pairs have been found when using an area model?

• The factors are all even numbers

• The factors are multiples of 5

• The factors are close to each other

• The factors are all odd numbers

What is the correct order of factor pairs for 20 from least to greatest?

• 5, 4, 2, 1, 10, 20

• 1, 2, 4, 5, 10, 20

• 20, 10, 5, 4, 2, 1

• 2, 4, 5, 10, 20, 1

What is the main takeaway from using area models to find factor pairs?

• They simplify multiplication

• They assist in identifying all factor pairs

• They help in adding numbers

• They are used for division
