What does the term 'fact family' mean?

Back

A fact family is a group of related addition and subtraction or multiplication and division equations that use the same numbers. For example, the numbers 3, 7, and 21 can form the fact family: 3 x 7 = 21, 7 x 3 = 21, 21 ÷ 7 = 3, and 21 ÷ 3 = 7.

What is the relationship between multiplication and division?

Back

Multiplication and division are inverse operations. If you multiply two numbers, you can divide the product by one of the numbers to get the other number.

Front

What is the product in multiplication?

Back

The product is the result of multiplying two or more numbers together. For example, in 4 x 5, the product is 20.

What is the quotient in division?

Back

The quotient is the result of dividing one number by another. For example, in 20 ÷ 4, the quotient is 5.

What is an area model in multiplication?

Back

An area model is a visual representation of multiplication that shows the area of a rectangle. For example, a rectangle with a length of 4 and a width of 6 represents 4 x 6.
