I Love to Read month

This year for I Love to Read month at school, I did something a little bit different.  In the past, I selected four authors and each week read a multitude of books by one author.  Then at the end of the week, students voted on their favorite. 
Instead of looking for four prolific authors this year, I chose 44 of my favorite picture books and read those throughout the month.  My students seemed to enjoy it just as well. What are your favorite picture books for kids?
