How do you calculate the total cost of items?

Back

To find the total cost, add the price of each item together. For example, if you buy 2 items for $3 each and 1 item for $2, the total cost is (2 x 3) + 2 = $8.

What is a fact family?

Back

A fact family is a group of related addition and subtraction or multiplication and division facts that use the same numbers. For example, the numbers 2, 6, and 12 can form the fact family: 2 x 6 = 12, 6 x 2 = 12, 12 ÷ 2 = 6, 12 ÷ 6 = 2.

What is the commutative property of multiplication?

Back

The commutative property states that changing the order of the numbers in a multiplication problem does not change the product. For example, 4 x 5 = 20 and 5 x 4 = 20.

Front

What is the associative property of addition?

Back

The associative property states that when adding three or more numbers, the way in which the numbers are grouped does not change the sum. For example, (2 + 3) + 4 = 9 and 2 + (3 + 4) = 9.

What is a rectangle?

Back

A rectangle is a quadrilateral with opposite sides that are equal in length and four right angles.

Front

What is division?

Back

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

What is a trapezoid?

Back

A trapezoid is a quadrilateral that has at least one pair of parallel sides.
