Long Division

Long Division

What does long division look like?

First you have to know when you need to divide.

• Are we needing to find a total of equal groups that we have? OR

• Do we already have a total and need to SPLIT them up into equal groups to see how many are in each (1) group?

Thinking Problem #1

The Galindo family went to Dos Salsas for dinner. They ordered 42 ounces of queso for an appetizer. There are 6 family members in the Galindo family. If they share an equal amount of queso, how many ounces would each family member get?

Multiple Choice

What makes sense for our Galindo family question?

• We will get an answer that is a smaller number than the 42 ounces of queso.

• We will get an answer that is larger than the amount of queso.

Think about what we know.

• A total of 42 ounces of queso.

• There are 6 family members to share it between.

• We will have to split it up. (Divide it)

• 42 divided by 6 = ?

• What does 6 multiply by to = 42?

Thinking question #2

• Jaime's soccer coach bought 40 bottles of water for the whole team. Each player receives 4 bottles of water. There are none left. How many players are on the team?

Multiple Choice

What makes sense when solving for how many players there are?

• There will be more players than water bottles so my number will be greater than 40.

• There will be less players than water bottles so my number has to be less than 40.

Think about...

• Picturing a soccer team and handing out 4 bottles to each person.

• You only have 40 to hand out total. You are not getting more.

• After you give out 4 to each person the 40 is all gone. So how many players must you have?

• You are taking 40 and splitting them up equally by 4's.

• 40 divided by 4 =

Poll

40 water bottles altogether

Each player gets 4 water bottles

How many players must there be on the team if all the water bottles are given away equally?

• 160 water bottles

• 80 water bottles

• 10 water bottles
