Black? White! Day? Night! A Book of Opposites by Laura Vaccaro Seeger, illustrated by the author, 2006 Roaring Brook Press. ISBN: 978-1-59643-185-0
Here's a clever picture book about opposites! We loved it so much, the kids told me this had to be a picture book of the week.
Each page has a one-work question, such as "alike?" Each page has one or more cut-out windows, showing a picture--in this case, several "alike" diamonds. Flip the page and the picture of an opposite concept is shown: the little "alike" diamonds were actually all part of several very differently-shaped snowflakes!
Have fun with his colorful and imaginative book of opposites!
