I know there is a plethora of books available for an Arctic and Polar Bear theme (our focus was polar bears), but these are the ones I chose from what was available from our library. I’ve included affiliate links to Amazon below. I appreciate the readers who use those links to make purchases. Thank you!

(added 12/2013: This book was too detailed when we did the Arctic Unit, but I do like these books a lot for learning about habitats. The Heart of Dakota curriculum uses them.)
