Understanding Factor Pairs and Distribution

The video tutorial teaches how to solve word problems by listing factor pairs. It begins with an introduction to factors and factor pairs, using examples like 3 times 4 equals 12. The tutorial then presents two word problems: one involving John and his 16 pieces of gum, and another with Ellie and her 20 mints. Each problem is solved by identifying all possible factor pairs, demonstrating how to create equal groups. The lesson concludes by reinforcing the concept of factor pairs as a method for solving similar problems.

What is the main problem Ellie is trying to solve with her treat bags?

• Finding the total number of mints

• Distributing mints equally in treat bags

• Counting the number of treat bags

• Calculating the cost of mints

Which of the following is a factor pair of 12?

• 6 and 5

• 3 and 4

• 7 and 1

• 5 and 2

Why is 5 not considered a factor of 12?

• Because 5 is a prime number

• Because 5 is greater than 12

• Because 5 is an odd number

• Because there is no whole number that multiplies with 5 to give 12

How many treat bags can John make if each bag has 8 pieces of gum?

• 4

• 2

• 1

• 8

What is the total number of factor pairs for the number 16?

• 6

• 3

• 4

• 5

Which of the following is NOT a factor pair of 16?

• 1 and 16

• 2 and 8

• 3 and 5

• 4 and 4

How many different ways can Ellie make treat bags with 20 mints?

• 7

• 6

• 5

• 4

Which factor pair represents 20 bags with one mint each?

• 20 and 1

• 4 and 5

• 2 and 10

• 1 and 20

What is the purpose of listing factor pairs in these problems?

• To calculate the total sum

• To determine equal groupings

• To identify prime numbers

• To find the largest number

What is the key takeaway from the lesson on factor pairs?

• Factor pairs are used to find the greatest common divisor

• Factor pairs help in solving word problems involving equal distribution

• Factor pairs are only applicable to even numbers

• Factor pairs are only useful for numbers less than 20
