"mille." But instead of meaning 1,000, it means one thousand thousands.

the thousands (1,000,000,000)

past the thousands (1,000,000,000,000)

less than 10 cents, offer to give them 10 pennies for a dime. After the trade, ask them
how much money they have (It will be the same). Then tell them to move the pennies.
Repeat until out of pennies. This should reinforce that they will have to trade or borrow.
