Money Savvy Generation

The Money Savvy Generation website contains products and resources to teach kids about money from 4 years of age through teenagers.
One of the resources you can sign up for is the “Helping Kids Get Smart About Money” E Newsletter.
The Money Savvy Saving Banks have 4 separate chamber for Save, Spend, Donate and Invest. The banks come as pigs in blue, pink, red, purple, green, and platinum and also as a clear cow or a football.
They have recently added an I-phone app/game, Savings Spree which teaches kids how the choices they make each day can add up to big savings or big expenses.  It is for children ages 7 and up (or younger with help from mom and dad or older sibling). 
This is one of many resources available to teach kids about money.
