Settlers of Catan is great. Others I have come across are Puerto Rico (great game, 3 to 5 players), Agricola (only played online, check out http://www.boiteajeux.net/ yuo will need to register but can play up to 40 games at a time for free - turn based, not real time so you log on and take your moves, then log off) and dominion (played at a friends house - pretty good).
Slightly simpler games that I have and play with the kids are Carcasonne (a tile-laying game), Ticket to ride (build train routes - my 5 year old can play this fine) and Memoir '44 (WWII, a sort of intro to tabletop war games).
