This site was created by the Israeli Embassy in Washington, D.C. to share with kids the story of Israel, its languages, currency, geography and food.  There are some nice coloring pages of hebrew letters, a lot of fun animation with really useful facts.  A very current and realistic view of Israel.  I think even young 4-6 yr old kids could enjoy it.  Certainly older kids will gain a lot from it.  There are even a few fun games.  http://www.israel4kids.org/
