OA.2: Write simple expressions that record calculations with numbers, and interpret numerical expressions without evaluating them. For example, express the calculation “add 8 and 7, then multiply by 2” as 2 × (8 + 7). Recognize that 3 × (18932 + 921) is three times as large as 18932 + 921, without having to calculate the indicated sum or product.

5.OA.2 Classwork1.pdfThe homework and test are going to look very similar to the problems on this page. The numbers will be different. You should try many of the problems on the example sheet to see if you can do them. Try some towards the top, and some near the bottom. If there are different types of problems on the same sheet, you should try at least two of each type. If you do not understand how to work anything on this page, ASK THE TEACHER. When you are finished practicing on this page, you can go to your Google Classroom and begin your homework.
Numerical Expressions vs. Word Form.mp4A Playlist of videos from YouTube about Writing Expressions is included on the left. You do not have time at school to watch each video! Click one, and if that doesn't help then you can click another. After that, you'll need to watch the rest during free time or at home. If both videos fail to help you understand, you need to ask me for help. :)
