Who wants to learn basic physical concepts from a boring human? The Dinosaur School series employs dozens of wildly colored, wide-eyed, gleefully grinning, computer-illustrated dinos to illustrate the most elementary of first lessons. This is all about clarity: the bright characters cavort across plain white pages, while a brief sentence in large font makes a single declaration. Both pages in each spread play off each other to highlight the two opposing concepts. Each left-hand page in Which Is Different? features three dinos, with one possessing something different, which is then isolated on the right-hand page. A couple of these will actually take adults a few seconds to spot, too at ice-cream cone looks a lot like those cookies! Occasionally ending with visual glossaries, this is fine sit-and-learn stuff for the tiniest tykes.
