- What do you notice? What do you wonder?
- Use pictures, models, or numbers to show what you know about the number of pages in the books or the time it takes to read them.
- What mathematical questions can you ask about this situation? Answer any questions you can!
- Estimate the total number of pages in one of each person’s books. Use a ratio table to estimate a total for each 5-book series.
- Assume all the books in each series are about the same length. Estimate how many pages are in each series.
- Show your work to someone else, and explain your thinking. Did they understand?
- Ask if they have any other questions you can answer!
Find a book you love. Read it for 15 minutes and see how many pages you read. Then use that information to find out how many pages you read in an hour. What if you read all day? How many pages would you read? How long would it take to read the whole book if you didn’t stop reading?
