"Bear about Town", written by Stella Blackstone and illustrated by Debbie Harter, is available in English and in French/English or Spanish/English bilingual versions.
The Beeman, written by Laurie Krebs and impeccably illustrated by Valeria Cis, is a cute and very educational book about a little boy whose grandfather is known around town as "the beeman". This is, of course, because his grandfather is a bee keeper. In my opinion, children as young as 3 will enjoy this book, although the official recommendation is ages 5-9.
"Barefoot Books World Atlas", written by Nick Crane and illustrated by David Dean, is a wonderful tool for learning. There is a very large pull-out world map in the back, sections on each geographic area, and lots of interesting tidbits for young--and not-so-young--students.
"The Boy Who Grew Flowers" (also available in French as "Des fleurs pour Angelina"), written by Jen Wojtowicz and illustrated by Steve Adams, just might be the most beautiful of all the Barefoot Books. And I mean that in terms of the illustrations, and also the story. Ms. Wojtowicz has said she drew the inspiration for the tale from her brother, who has autism.
I absolutely love The Girl with a Brave Heart for many reasons. It is a traditional tale from Tehran, retold by Rita Jahanforuz and illustrated by Vali Mintzi. So right there, I am a fan, because I believe it is important to expose children to positive things from Iran (and other "enemy" nations) in order to help our kids understand that Iranians are indeed people, just like we are.
The "Words Books" are three largely identical books: My Big Barefoot Book of Wonderful Words, My Big Barefoot Book of French and English Words, and My Big Barefoot Book of Spanish and English Words. Wonderful Words has the words in English only, and the other two have them in English and French or Spanish.
The Barefoot Book of Children is, quite simply, the most powerful children's book I have ever read. (And yes, that includes To Kill a Mockingbird and The Little Prince, my two previous favorites.) And all of my children (including Atticus, when he was alive) are just fascinated by it.
