Topic 3 Test

Front

What is multiplication?

Back

Multiplication is a mathematical operation that represents the repeated addition of a number. For example, 4 x 3 means adding 4 three times: 4 + 4 + 4 = 12.

Front

What is the product of 4 x 1,817? Show your work.

Back

The product of 4 x 1,817 is 7,068. (4 x 1,817 = 7,068)

Front

What strategy can you use to find the product of 346 x 8?

Back

You can use the distributive property: 346 x 8 = (300 + 40 + 6) x 8 = 2400 + 320 + 48 = 2,768.

Front

What does it mean to circle the model in a multiplication problem?

Back

Circling the model means identifying the correct visual representation of the multiplication problem, which helps in understanding the concept.

Front

What is the product of 2,361 and 4?

Back

The product of 2,361 and 4 is 9,444. (2,361 x 4 = 9,444)

Front

How do you solve for the product of 29 x 34 using a model?

Back

You can use an area model or a number line to visualize the multiplication, leading to the final product of 986.

Front

What is the definition of a factor in multiplication?

Back

A factor is a number that is multiplied by another number to get a product. For example, in 4 x 5, both 4 and 5 are factors.

Front

What is the commutative property of multiplication?

Back

The commutative property states that changing the order of the factors does not change the product. For example, 3 x 4 = 4 x 3.

Front

What is the associative property of multiplication?

Back

The associative property states that the way in which factors are grouped does not change the product. For example, (2 x 3) x 4 = 2 x (3 x 4).

Front

What is a multiplication model?

Back

A multiplication model is a visual representation of a multiplication problem, such as an array or area model, that helps in understanding the concept.
