What To Do With Remainders By the end of this lesson, you will know three different ways to handle a remainder in real life.

My division problem has a remainder. Now what do I do? Problems with a remainder require you to be extra thoughtful. This activity will teach you how to deal with remainders in real life.

Once you’ve got a remainder, Ignore It! Use It! It’s your answer! Round Up!

Mrs. Bushell will fill 7 pages. Ignore It! Mrs. Bushell is organizing her recipes into a binder. Exactly 4 recipes fit on each page. She has 29 recipes. How many pages will Mrs. Bushell fill? 29 ÷ 4 = 7 R 1 What does the 1 represent? The 1 is the extra recipe that will go on a new page, but that page will not yet be filled. What does the 7 represent? The number of pages that will be filled. In order to answer the question, I need to IGNORE the remainder. Mrs. Bushell will fill 7 pages.

There will be 1 student left after groups are formed. Use It! It’s your Answer! The students in Miss Joseph’s class are forming groups of 4 for a math game. There are 29 students in her class. How many students will be left after groups of 4 are formed? 29 ÷ 4 = 7 R 1 What does the 7 represent? The number of groups that are formed. What does the 1 represent? The number of students who will be left after the groups are formed. In order to answer the question, I need to USE the remainder. There will be 1 student left after groups are formed.

8 X 4 = 32, so 8 boxes will be enough cupcakes Round Up! Mrs. Pascarella is buying cupcakes for her class. The cupcakes come in boxes of 4. There are 29 students in her class. How many boxes of cupcakes does Mrs. Pascarella need to buy if she wants to give each student a cupcake? 29 ÷ 4 = 7 R 1 What does the 7 represent? At least 7 boxes of cupcakes will need to be ordered. What does the 1 represent? The number of students who would not get a cupcake if only 7 boxes of cupcakes are ordered. I need to ROUND UP so that everyone gets a cupcake. Instead of 7 boxes of cupcakes, she needs to order 8 boxes. 8 X 4 = 32, so 8 boxes will be enough cupcakes

Can you name the three ways you can handle remainders? Ignore the remainder. Use the remainder. It’s your answer! Round your answer up.
