How do they earn money? For every minute of reading for Jack and workbook work for Nate they earn a penny. Every penny equals a minute; you see how this plays out? They can earn extra for doing chores and they can lose minutes for being naughty. So far each boy has accumulated 30 minutes. Maddie wanted in on the gig too, so she just does some stuff and I give her pennies. She doens't play wii, but she may just learn a little about spending, saving, and time being money, that whole thing.
Now, aren't I clever? (For the moment anyway).
