I'll list the titles that I know about in this post. Try the library first - see if you like them, and then by all means, buy them for your shelves. These are often available on eBay. Here is the rest of the verbage taken from the back of the This Book's About Time book:
"The Brown Paper School is a series of small books about big ideas, written and designed for kids and grownups together. The series comes from a group of California teachers, writers, and artists who get together every now and then to work on stuff for kids and to have a good time. They believe that learning can happen anywhere, and that it doesn't require fancy tools. This book and the others in the series are dedicated to anyone who thinks so, too."
On with greatness! Here are the titles I'm aware of, but you can bet I'll be hunting for more........

And the titles for which I could not locate pictures:
And finally, here is a link that leads to a page containing most, if not all, of the math books for kids by Marilyn Burns. She is a cornerstone in the Brown Paper School book movement, a teacher, and an author. She teaches teachers how to teach math and is well-known and respected as an educator.
If you'd like to learn more about Ms. Burns, you can find that information here:
(funny how Scholastic doesn't mention her involvement with Brown Paper School publishing...hmm)
