What does an array represent in multiplication?

Back

An array is a visual representation of multiplication, showing objects arranged in rows and columns. For example, 3 rows of 4 objects each represent 3 x 4.

Front

What is the equation for an array with 5 rows and 3 columns?

Back

5 x 3 = 15.

Front

How can you find the total number of objects in an array?

Back

Multiply the number of rows by the number of columns. For example, if there are 4 rows and 5 columns, the total is 4 x 5 = 20.

Front

What is the relationship between multiplication and division?

Back

Multiplication and division are inverse operations. If 3 x 4 = 12, then 12 ÷ 4 = 3.

Front

What does the multiplication sentence 4 x 3 mean?

Back

It means there are 4 groups of 3 objects each, totaling 12 objects.

Front

What is an equal group?

Back

Equal groups are groups that have the same number of items. For example, if you have 3 groups of 5 apples, each group has 5 apples.

Front

How do you write a multiplication sentence for equal groups?

Back

Count the number of groups and the number of items in each group. For example, 4 groups of 2 items each is written as 4 x 2.
