I was really disappointed in this book, being such a fan of her other work. The photos here are too busy to really see what's going on. There's a crowded photo of a little girl doing something (playing with a train, building with blocks, riding a bike) and then you turn the page and there's a big photo of a shape that was in the page before, not conducive to teaching shapes (so the train track made an oval, One of the blocks was a rectangle). I expected simpler more child friendly photos and was sad. Many of her others are good though.
