• # Dividing Decimals with Models

Aubrey’s mom is planning to make her famous orange limeade and asks Aubrey to go to the store. Aubrey ended up buying 3 oranges for a total of \$2.67. How much does each orange cost?

“What is division?”
Division is when you take the total of something and split it up equally.

## #1 Make the model: 2 wholes / 6 tenths / 7 hundredths

“Now what do we have to do with 2 wholes / 6 tenths / 7 hundredths?”
Split it up into 3 groups.

“Can we split 2 wholes into three groups?”
No, there is not enough. We can take the wholes and break each of them apart!
1 whole = 10 tenths

## #2 Break up the wholes and exchange each of them for tenths. 1 whole = 10 tenths

There are a total of 26 tenths now

“Now what do we do?”
Count up how many tenths we have and split them up into 3 groups. 26 tenths ÷ 3
We will find how tenths are in each of the 3 groups.

## #3 Divide the tenths

26 tenths ÷ 3 = 8 tenths in each group R2 tenths left over + 7 hundredths

“What do we do with the 2 tenths and 7 hundredths?”
Do the same thing. Take the tenths and break each of them apart into hundredths.
1 tenths = 10 hundredths

## #4 Break up the tenths and exchange each of them for hundredths. 1 tenth = 10 hundredths

“What’s next?”
Count up how many hundredths we have and split them up into 3 groups. 27 hundredths ÷ 3
We will find how hundredths are in each of the 3 groups.

## #5 Divide the hundredths

27 hundredths tenths left over ÷ 3 = 9 hundredths in each group

“Put everything together! How much did each orange cost?”
When we take 2 wholes, 6 tenths, 7 hundredths and split them equally into three groups =  8 tenths in each group & 9 hundredths in each group
Each orange cost \$0.83

• # Understanding Remainders | Division

For lower performing students, with enough practice, they can develop the math skill – but the question is – how do we help these students develop skills to be able to apply their math skills when they encounter word problems? In word problems, the most important thing is to be able to understand what the question […]
