Recently, I bought three books:
- “Schools on Trial” of Nikhil Goyal  (discovered via Idzie Desmarais ) for knowing what I have to change
- “The Best of the Math Teacher Blogs 2015” by Lani Horn and Tina Cardone  for knowing what I could do
- “De los principios a la acción: Para garantizar el éxito matemático para todos”  (spanish edition of “Principles to Actions: Ensuring Mathematical Success for All” ) for knowing what USA citizens face teaching
Here is a photo of the whole set:
I don’t know if I will have time to read them before next course.
