Understanding Factor Pairs

This video tutorial teaches how to find all factor pairs of a number using a T-chart. It begins by defining factors and explaining the commutative property of multiplication. The tutorial then demonstrates how to use a T-chart to systematically find factor pairs, using the number 12 as an example. The process involves listing factors in pairs and ensuring no factors are missed by checking the number line.

What is a factor of a number?

• A number that cannot be divided by another number.

• A number that can be divided by another number without a remainder.

• A number that is always greater than the product.

• A number that is always less than the product.

Which of the following demonstrates the commutative property?

• 2 - 3 = -1

• 2 + 3 = 5

• 2 x 3 = 6 and 3 x 2 = 6

• 2 / 3 = 0.67

Why is it important to include the number itself when listing factor pairs?

• Because it is not a factor.

• Because it is always the largest factor.

• Because it is always the smallest factor.

• Because it is a factor of itself.

What is the first step in using a T-chart to find factor pairs?

• Start with the number zero.

• Start with the smallest factor.

• Start with the largest factor.

• Start with the number itself.

How does the T-chart help in finding factor pairs?

• It eliminates all non-factors.

• It calculates the product automatically.

• It visually organizes factors to easily identify pairs.

• It lists all possible numbers.

What is the first factor pair you should write when using a T-chart for the number 12?

• 6 and 2

• 2 and 6

• 3 and 4

• 1 and 12

Which factor pair of 12 is found after 1 and 12?

• 4 and 3

• 3 and 5

• 2 and 5

• 2 and 6

What indicates that you have found all factor pairs using a T-chart?

• When the numbers on the left and right are equal.

• When the numbers on the left are greater than the right.

• When the numbers on the left and right are next to each other on the number line.

• When the numbers on the right are greater than the left.

Which of the following is NOT a factor pair of 12?

• 5 and 2

• 3 and 4

• 2 and 6

• 1 and 12

What is the purpose of using a T-chart in finding factor pairs?

• To find the largest factor.

• To simplify the multiplication process.

• To eliminate non-factors quickly.

• To systematically list and verify all factor pairs.
