We bought the kids their first board game recently. Its called "Supermarket". Its a little bit like kiddie monopoly but much more simplified. The kids get to roll a dice and move around the board over and over again. They get to stop to do some "shopping" with pretend money if they happen to stop at a square with a shopping trolley.
When I have more time, I may upload a photo and do a small "review" of the game. In the gist, I think board games are great family fun. However, with young kids, you must set aside a time to sit with them, explain the game and supervise the play. Oh and don't forget to explain that you don't have to win all the time to enjoy a game. lol.
In this game, they learn about money, counting etc but the most important lesson of all is the lesson on losing and winning and being sporting when playing. :)
