Interesting boardgames to play with children
Legendary Uno. Its card game. Description from BGG:


  Players race to empty their hands and
  catch opposing players with cards left
  in theirs, which score points. In
  turns, players attempt to play a card
  by matching its color, number, or word
  to the topmost card on the discard
  pile. If unable to play, players draw
  a card from the draw pile, and if
  still unable to play, they pass their
  turn. Wild and special cards spice
  things up a bit.
