Fifty irresistible puzzles take kids on a trip around the world, from Paris to Peru, Aruba to the Alps, Thailand to Tanzania, and Ghana to Greece. Each simple picture puzzle challenges children to focus, observe, count, and compare pictures to find subtle (and hilarious) differences between them. Who gave the Queen's Guard ice cream? What's that on top of the Great Pyramid? Why does St. Basil's look so silly? When did a soccer ball turn into a watermelon?! Kids will have a blast pointing out the things in each picture that have changed--and they'll hone important skills while they play!
