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 the total number of items if there are 3 items on each of 7 tables?

Back

To find the total, multiply the number of items per table by the number of tables: 3 items/table x 7 tables = 21 items.

How do you find the total number of apples in 6 rows if there are 7 apples in each row?

Back

Multiply the number of apples per row by the number of rows: 7 apples/row x 6 rows = 42 apples.

Front

What is division?

Back

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

Front

If Julie had 72 sunflowers and threw away 9, how many does she have left?

Back

Subtract the number of sunflowers thrown away from the total: 72 - 9 = 63 sunflowers left.

Front

How do you distribute items equally among groups?

Back

To distribute items equally, divide the total number of items by the number of groups. For example, if you have 63 sunflowers and 9 vases, you would do 63 ÷ 9 = 7 sunflowers per vase.

Front

If Jessie's dad had $459 and spent $67 and $121, how do you find out how much he has left?

What is a carton in terms of eggs?

Back

A carton is a container that holds a specific number of eggs. For example, a standard egg carton holds 12 eggs.

Front

How do you find the number of cartons if you have 24 eggs?
