Caps for Sale 
by Esphyr Slobodkina

Why we liked this book:  Kind of just a fun book to read.  I had the kids count how many caps there were in each color so it is a good counting/learning your colors book.

Activity:  The kids made their own caps out of a paper plate, string and whatever random things we had to decorate the caps with.  We used markers and pom-poms.  Then they ran around the house yelling, "Caps for sale!  50 cents a cap!"
