Lesson 3: Split Numbers to Multiply Flashcard

Front

What is the distributive property in multiplication?

Back

The distributive property states that a(b + c) = ab + ac, meaning you can distribute the multiplication over addition.

How do you simplify the expression (1 + 3) x 9?

Back

You can simplify it by calculating the sum first: (1 + 3) = 4, then multiply: 4 x 9 = 36.

Front

What is the result of (2 x 9) + (2 x 9)?

Back

The result is 36, which is equal to 4 x 9.

Front

Is (4 x 4) + (4 x 4) equal to 4 x 9?

Back

No, (4 x 4) + (4 x 4) equals 32, which is not equal to 36.

Front

What does it mean to split numbers in multiplication?

Back

Splitting numbers in multiplication involves breaking down numbers into smaller parts to make calculations easier, often using the distributive property.

Front

How can you represent 6 plates with 7 muffins each using an expression?

Back

You can represent it as (7 x 4) + (7 x 2) to show the total number of muffins.

Front

What is the value of 4 x (3 + 6)?

Back

The value is 36, since 3 + 6 = 9, and 4 x 9 = 36.

Front

What is the importance of using a model in multiplication problems?

Back

Using a model helps visualize the problem, making it easier to understand and solve.

Front

How do you check if two expressions are equal?

Back

You can evaluate both expressions and compare their results to see if they are equal.

Front

What is the first step in solving the expression (1 + 3) x 9?

Back

The first step is to calculate the sum inside the parentheses: 1 + 3 = 4.
