I recommend the 99 Haskel problems: http://www.haskell.org/haskellwiki/H-99:_Ninety-Nine_Haskell_Problems http://www.haskell.org/haskellwiki/H-99:_Ninety-Nine_Haskell... All questions have solutions you can learn from; most have multiple solutions. I have learned a lot from doing these problems and doing additional research where needed. (This is in addition to the other good learning resources like the oft mentioned LYAH.)
