Jamal has $400 to spend on a camping trip. He knows he will have to spend at least $15 a day on food and expenses.
What do you notice? What do you wonder?
Notice responses might include: (highlight to see)
- Jamal has $400 now
- Jamal will spend at least $15
- At the beginning of the 2nd day, he will have less than $385
- In 10 days, he will have less than $400-$150
- We don’t know how long he is going for.
Wonder responses might include:
- How much money will he have after 4 days
- How long before he has no more money?
- How much money will he have at any time during the trip?
- If he has $183, how long has he been on the trip?
Now answer all of the above wonder questions, as well as any that you thought of.
In particular let’s explore the following:
How can we mathematically represent the amount of money Jamal may have at any point in the trip. And, what are some other questions you could answer about this situation?
