Want to give your students a seemingly unlimited number of logic puzzles and brainteasers to delve into over the summer?  Try out Erich’s Puzzle Palace.  There are several ways you can sort this huge collection: Math, Word, Grid, and Path are only some of them.  I haven’t tried all of them, or even most of them, so I cannot tell you what grade levels are encompassed.  However, I got stumped on the very first Color Maze puzzle I tried, so now it looks like I’ll be spending by entire summer trying to figure those out 😉
