The best way to help a young mind develop is by challenging it with puzzles and games. The ones that were the most fun were always the I Spy books or games. They first came out in 1992 and ever since kids have been searching for thimbles and buttons in a pile of stuff for decades.
Were you a master of the I Spy game? Think you can still find the objects? It's obviously intended for kids but you know what, some of them make me feel like I am blind.
How did you do? Did you find them all or are you super frustrated?
Challenge your friends and see who does it best! Or, you can take it to the next level and pick up some new books to teach your kids how it's done!
