Ignore the Remainder 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 DROP the remainder. Mrs. Bushell will fill 7 pages.
Use the Remainder. 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.

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.
Round Up Mrs. Pascarella is buying cupcakes for her class. The cupcakes come in boxes of 4. There are 29 students in her class.
