How do you solve a one-step multiplication problem?

Back

To solve a one-step multiplication problem, multiply the given number by the number of groups. For example, if there are 5 groups of 2, you calculate 5 x 2 = 10.

How do you solve a one-step division problem?

Back

To solve a one-step division problem, divide the total number by the number of groups. For example, if you have 20 cookies and want to share them with 4 friends, you calculate 20 ÷ 4 = 5.

Front

What is a two-step multiplication problem?

Back

A two-step multiplication problem involves two operations. For example, first multiply 3 x 4, then add 2: (3 x 4) + 2 = 12 + 2 = 14.

How do you find the total number of items in equal groups?

Back

To find the total number of items in equal groups, multiply the number of groups by the number of items in each group. For example, 4 trays with 9 cookies each means 4 x 9 = 36 cookies.

Front

How do you find the remaining items after some are taken away?

Back

To find the remaining items after some are taken away, subtract the number taken from the total. For example, if you have 36 cookies and sell 17, you calculate 36 - 17 = 19.

Front

What does it mean to multiply a number by 6?

Back

Multiplying a number by 6 means you have 6 groups of that number. For example, if you multiply 3 by 6, you have 3 + 3 + 3 + 3 + 3 + 3 = 18.

Front

How do you calculate the total number of slices from pizzas?

Back
