One spatial reasoning favorite in our class is a game called, “Royal Rescue.”  The game comes with blocks, a prince and princess, and challenge cards.  Students must set up the blocks according to the challenge cards, and use the indicated remaining blocks to build a route for the prince and princess to travel to get to each other.  (Some view it as the prince rescuing the princess, and others see it the other way around!)  The challenges increase in difficulty, and our group just made it to the Expert level today.  Solving some of these puzzles literally requires that you “look at things from another perspective,” and the students are getting very good at asking themselves, “What haven’t I tried yet?”
