One title not included in any of these lists which I recommend for all testing in Mind Benders. Mind Benders teach deductive logic. This is a skill use to make headway when you read a question and don't know the answer. Deductive logic enables you to eliminate (a) and (b) (for example) as clearly false enabling you to improve your probability of guessing correctly by choosing (c) or (d). Most children enjoy solving Mind Benders puzzles. Checking that you've got the correct solution to your Mind Bender puzzle provides practice in proof reading and checking test answers. Finally the type of reading required to solve these puzzles - every word matters - is exactly what is required for multi-choice testing.
