Language / Polish websites for a beginner reader [5]

Hello all,
I have a question on language learning resources I haven't been able to find in the archives. I've been studying polish for a few years and while I'm conversationally fluent I still have a pretty limited vocabulary. I'm hoping to find some resources online which will let me practice reading polish without making me look up every other word! I'd love the equivalent of the simple English wikipedia, or something targeted at younger children, but most of what I've managed to find for children was limited to silly flash games. Anyone have links they can send my way?

thanks!
