puzzlemaker.co.uk is a great site for teachers looking for reinforcement activities for pupils. you can make customised puzzles, mazes and wordsearches to suit your needs and your pupils! I used it to make up worksheets to recap on french vocabulary for a class of less able 14 year olds. as a learning support teacher i know these pupils need lots of diferent activities using the same vocab. they enjoyed the work and did not find it patronising or babyish. the biggest problem was that the worksheets need a bit of spicing up to make them more attractive.
