How much cash is that? How many coins are there?
Write a wrong answer for both questions.
Write your best guess for both questions.
- Teacher noteHere's the plan. Release a single piece of information, then ask them to figure out possible solutions. Then release the next piece of information. Ask them to figure out possible solutions.
This may involve a lot of guessing and checking.
If so, you should feel free to step in and show them how mathematicians solve similar problems quickly, with no guess-and-checking at all.
Fact #1: The cash is worth $62.00.
Fact #2: There are 1,400 coins.
