Understanding Division Expressions and Models

This lesson introduces writing division expressions in two forms: using the division symbol and as fractions. It covers examples of writing expressions without the division symbol, using models and variables. The lesson also explores complex expressions involving multiple terms and provides exercises for practice.

What are the two forms of writing division expressions introduced in the lesson?

• Dividend minus divisor and dividend plus divisor

• Dividend multiplied by divisor and dividend minus divisor

• Dividend divided by divisor and dividend over divisor

• Dividend plus divisor and dividend times divisor

How can you represent the division of 8 by 2 using a model?

• By using an array with 2 rows

• By creating a model with 4 parts

• By drawing a model with 8 sections

• By dividing a whole into 2 equal parts

In the example of writing 1/2 as a division expression, what does the model represent?

• A whole divided into four parts

• A whole divided into five parts

• A whole divided into three parts

• A whole divided into two parts

In the expression 'a divided by b', what does 'b' represent?

• Quotient

• Dividend

• Numerator

• Denominator

How would you write 'G divided by the quantity of H plus 3' using a fraction?

• H plus 3 times G

• G times H plus 3

• H plus 3 over G
