New Teacher's Guides for Feynman and Primates

First Second and I have created new teacher's guides for Feynman and Primates . They look great (that's because of First Second's fabulous designers) and are full of useful information about the books (I can take some credit for that part). 
We think teachers...and casual readers too...will find them useful. You can find them at the links above. 
And, thanks for reading these, and all my other stories. As Banned Books Week approaches I'm inclined to paraphrase the oft-banned George Orwell and say that all readers are equal, but some readers are more equal than others. Those are the ones who head towards the bibliographies I include in my books and then read even more about these scientists!
