Wooden puzzles are great for little kids; the pieces are easy to handle and fit more clearly into spaces. These beautiful wooden puzzles by German company Grimm's will appeal to kids of all ages, though. I'm thinking about putting one of these on my Christmas list.
These puzzles break traditional boundaries; they are more like block sets that can function as puzzles. Try to fit them back into their frame in as many different configurations as you can set up, or build your own designs by arranging the geometric pieces. All the wood is treated with non-toxic, lead-free, water-based stain.
