I don’t know who comes up with these holidays. But according to my Dover Publications newsletter, tomorrow (August 2nd) is National Coloring Book Day.
Sounds like a good excuse to play some math!

Denise Gaskins' Let's Play Math 
Can’t leave without mentioning the coloring books from Edmund Harriss and Alex Bellos. Patterns of the Universe, https://www.goodreads.com/book/show/25810669-patterns-of-the-universe, and Visions of the Universe https://www.goodreads.com/book/show/29430947-visions-of-the-universe. So much math in those!
Yes, wonderful books!
I thought at first I might include a section of “Books to Buy” in the post, as well as the free downloads. But I accidentally hit Publish, so I decided to go with what I had.
Anna Weltman’s books are also great: http://www.bookdepository.com/author/Anna-Weltman
