Dogs by Emily Gravett
This book presents a good opportunity to talk about how there are different breeds of the same kind of animals. Use a size comparison chart you can find online to laminate and cut apart so children can divide breeds into classification groups of small and large dog breeds. This classification sorting activity could also be extended to other breed characteristics, for example, which dogs have brown (black, white, spotted, long, short) hair?Tails? Ears? Etc.
