Tips for grownups listening to “Million Bazillion” with kids

Money Talks

After you listen to the episode, here are some questions and conversation starters you can use with your kid listener to see how much they learned:

  1. Why would someone want to use an ATM?

  2. Would you prefer to use an ATM or talk to a person at the bank?

  3. If you could rename the penny, what would you call it?

  4. Why do airline ticket prices change?

  5. How much money do you think the president or a member of Congress should make?

  6. *Bonus* Not-So-Random Question: If you could use ATM machines to dispense something other than money, what would you want from it?
