Here are the Caldecott Medal Winner books the Ant Bug and I read during the months of July and August.
1960: Nine Days to Christmas, illustrated by Marie Hall Ets; text: Marie Hall Ets and Aurora Labastida
1961: Baboushka and the Three Kings, illustrated by Nicolas Sidjakov; text: Ruth Robbins
1976: Why Mosquitoes Buzz in People's Ears, illustrated by Leo & Diane Dillon
1978: Noah's Ark by Peter Spier
1979: The Girl Who Loved Wild Horses by Paul Goble
1989: Song and Dance Man, illustrated by Stephen Gammell; text: Karen Ackerman
1997: Golem by David Wisniewski
1999: Snowflake Bentley, Illustrated by Mary Azarian; text by Jacqueline Briggs Martin
The Ant Bug really enjoyed Song and Dance Man, and Noah's Ark is wonderfully illustrated (there are no words). The other books are meant for a more mature audience than my 4 year old, so she didn't have much interest in them.
