Interpreting Remainders Review

Interpreting Remainders Review

Dividing with 2-Digit Divisors

Review the Options

• Ignore it

• Round it (add one more group)

• Use it (the remainder IS the answer)

• Split it (make it a decimal or fraction)

Time to Solve!

• Solve the division problem to the right on your whiteboard. (Hold up your whiteboard when you have the answer)

• This will be the same problem for every word problem.

• However, we will have to read each problem carefully to determine what to do with the remainder.

Check Your Work

Did you get the same quotient and remainder?

Time to

TEST YOUR KNOWLEDGE!

Read each problem carefully and decide what you will do with the remainder. Each problem uses the exact same division problem we just solved.

Mrs. Finnegan bought a bag of 3,862 mini candy canes to give to her students. If she splits them equally between her 26 students, how many candy canes does each student get?

Multiple Choice

How should we interpret this remainder?

• Ignore it

• Round it (add another group)

• Use it (the remainder IS the answer)

Each student gets 148 candy canes.

IGNORE IT! In this problem, we ignore the remainder because Mrs. Finnegan is dividing equally and giving each student the same amount. The remainder represents 14 extra candy canes.

At the Kawanza festival, event coordinators only allow 26 people to enter the event at a time. A horn sounds each time to allow a new group to enter. If there were 3,862 people waiting to enter the festival, how many times would the horn sound?

Multiple Choice

How should we interpret this remainder?

• Ignore it

• Round it (add another group)

• Use it (the remainder IS the answer)

The horn will sound 149 times.

ROUND UP! In this problem, we have to round our answer up to the next whole number (149 times). Even though the last group isn't full, we can't leave anyone out. So, the horn will sound 148 times for each full group of 26 people, and one last time for the last group of 14 people to enter the festival.

Amanda is making a scrapbook of pictures for her parents for Hanukkah. She has 3,862 pictures, and she can put a maximum of 26 pictures on each page. If she includes all of her pictures, how many pictures are on the last page of the album?

Multiple Choice

How should we interpret this remainder?

• Ignore it

• Round it (add another group)

• Use it (the remainder IS the answer)

The last page will have 14 pictures.

USE IT! The remainder IS the answer. The quotient tells how many pages will be completely full, and the remainder tells how many pictures are left over. Because she has to include all of the pictures in the album, she will put the remaining 14 pictures on the last page.

Poll

How do you feel about being able to interpret remainders in word problems?

BREAKOUT ROOM ACTIVITY

• Now it's YOUR turn to write the story! You have been split into small groups and assigned a joint Google Slideshow to work on as a team.

• You will start by choosing one person to be the "presenter" (this person will present their screen to the class), one person to be "announcer 1" (this person will read the story problem aloud), and a 3rd person to be "announcer 2" (this person will give the answer and explanation).

• After choosing jobs, you will write a story problem using the same equation we used above that requires the remainder to be interpreted according to what is listed on your assigned slideshow.

BREAKOUT ROOM ACTIVITY

• After you write your story problem, you will cover up the answer with the black box on the slide.

• Mrs. Finnegan will post a POLL for all students to answer how they think the remainder should be interpreted.

• While presenting to the class, the "presenter" will uncover the box to reveal the answer.

• You will have 7 minutes to work with your group before returning to the main call.
