Multiplication Models & Strategies

Front

What is the multiplication model used to find the total number of items in equal groups?

Back

The multiplication model involves multiplying the number of groups by the number of items in each group (e.g., total = number of groups × items per group).

How do you represent the total number of items when you have 5 packages of 8 items each?

Back

You can represent it as 5 × 8 = total number of items.

What does the expression 3 x 14 represent in the context of the parking lot problem?

Back

It represents that there are 3 times as many trucks as cars in the parking lot.

Front

What are two number sentences that can be represented by the model showing 2 groups of 5?

Back

The two number sentences are 2 × 5 = 10 and 5 + 5 = 10.

Front

What is the multiplication sentence for the example of 3 groups of 6?

Back

The multiplication sentence is 3 x 6 = 18.

Front

What is the purpose of using multiplication models in problem-solving?

Back

Multiplication models help visualize and understand the relationship between groups and the total quantity.

Front

How can you verify the result of a multiplication problem using addition?

Back

You can verify by adding the same number repeatedly (e.g., for 3 x 4, add 4 three times: 4 + 4 + 4 = 12).

Front

What is the difference between a multiplication sentence and an addition sentence?

Back

A multiplication sentence shows repeated addition of equal groups, while an addition sentence simply adds individual quantities.
