We have plenty of easy and medium puzzles in our homeschool room drawers. Those haven't been out in a while. But Dorito found a Double-Sided Puzzle in Washington DC and thought it would be perfect gift for the twins now that they are older. Of course, it was. They tackled it the first morning on the kitchen island. Next day, Winger jumped at the chance to do the other side (which side is the front?) and then Polar Bear tore it apart and solved it the other way. We left it out all week and discussed facts related to the 16th president and his cabinet. Actually, other visitors also worked the puzzle between violin lessons, too. Nice!
