Understanding Area Models and Factors

What is a factor?

• The numbers that are multiplied together to get another number (Example: 3×4=12, with 3 and 4 being the factors)

• The number that is the answer to a multiplication sentence (Example: 3×4=12, with 12 being the factor)

• The number that is the answer to a division problem (Example: 12÷3=4, with 4 being the factor)

• The number that is being divided in a division problem (12÷3=4, with 12 being the factor)

A rectangular picture or model used to show how larger numbers can be broken down by place value when multiplying is called a what?

What is a product?

• The numbers that are multiplied together to get another number (Example: 3×4=12, with 3 and 4 being the products)

• The number that is the answer to a multiplication sentence (Example: 3×4=12. with 12 being the product)

• The number that is the answer to a division problem (Example: 12÷3=4, with 4 being the product)

• The number that another number is being divided by (Example: 12÷3=4, with 3 being the product)
