I like the MathStart Series *in general* but I wish there was more consistency from book to book. "Henry the Fourth" which explored ordinal numbers was great. The story had a cute plot and it kept my children's interest. "Missing Mittens"  (which was all about even and odd numbers) had a clumsy rhyme and it  wasn't nearly as good. This book about comparing-and-contrasting sizes is different still. It has too few words and virtually no plot. Take a look at the sentences from the first *3 pages*:. "I am big. ". "I am bigger than you are. ". "I am the biggest bug by far. ". Not much plot development there, and while the pictures detail  more activity, it is insufficient for young readers/viewers. On the bright side the `summary' pages are good. They show the 3 bugs currently under discussion (small, smaller, smallest, for example) in juxtaposition which makes it easy to talk about the concepts. So I would say that if you are willing to compose a story to go along with the pictures you can use this book to successfully teach your children about relative size. Without your input though they aren't going to get much out if it. Material covered in "Best Bug Parade":. Big, bigger, biggest. Small, smaller, smallest. Long, longer, longest. Short, shorter, shortest. Good, Better, Best. And as usual there are 2 pages of related activities suggested at the end of the book. Pam T~
