How do you calculate the total number of items given to a group?

Back

To find the total number of items given to a group, multiply the number of items each person receives by the total number of people. For example, if each student gets 3 Buzz Bucks and there are 123 students, the total is 3 x 123.

Front

What is the formula for finding the total number of crackers eaten in a certain number of days?

Back

The formula is: Total Crackers = (Crackers per day) x (Number of days). For example, if 2 packets of crackers are eaten per day, and each packet has 10 crackers, then in 3 days, it is 2 x 10 x 3.

Front

How do you find the total number of pencils given to students?

Back

To find the total number of pencils, multiply the number of students by the number of pencils each student receives. For example, 22 students each getting 43 pencils means 22 x 43.

Front

What is the total number of buttons used if 3 dresses are made each day for 4 days, and each dress has 2 buttons?

Front

What is the relationship between multiplication and division?

Back

Multiplication and division are inverse operations. If you know that 4 x 5 = 20, then you can also say that 20 ÷ 5 = 4.
