STAAR Review Multiplication and Division

Front

What is multiplication?

Back

Multiplication is a mathematical operation where a number is added to itself a certain number of times. For example, 3 multiplied by 4 (3 x 4) means adding 3 four times: 3 + 3 + 3 + 3 = 12.

Front

What is division?

Back

Division is a mathematical operation where a number is split into equal parts. For example, 12 divided by 3 (12 ÷ 3) means splitting 12 into 3 equal parts, which equals 4.

What does the term 'factor' mean in multiplication?

Back

A factor is a number that is multiplied by another number to get a product. For example, in 3 x 4 = 12, both 3 and 4 are factors.

Front

What is a product in multiplication?

Back

The product is the result of multiplying two or more numbers together. For example, the product of 5 and 6 is 30.

Front

What is a quotient in division?

Back

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

Front

How do you represent multiplication in a word problem?

Back

In a word problem, multiplication can be represented by phrases like 'times', 'each', or 'total of'. For example, 'There are 4 bags with 5 apples each. How many apples are there in total?' (4 x 5 = 20).

Front

What is the relationship between multiplication and division?

Back

Multiplication and division are inverse operations. This means that if you know the product, you can find one of the factors by dividing. For example, if 3 x 4 = 12, then 12 ÷ 4 = 3.

Front

What is the multiplication table?

Back

The multiplication table is a chart that shows the products of pairs of numbers. It helps in learning and memorizing multiplication facts.

Front

What is the commutative property of multiplication?

Back

The commutative property states that changing the order of the numbers in multiplication does not change the product. For example, 2 x 3 = 3 x 2.

Front

What is the associative property of multiplication?

Back

The associative property states that when multiplying three or more numbers, the way in which the numbers are grouped does not change the product. For example, (2 x 3) x 4 = 2 x (3 x 4).
