If you love Building Thinking Classrooms in Mathematics but want more examples of tasks you can use with your middle and high school students, this is the book you’ve been waiting for. It goes deeply into fifty tasks, how to launch them, the task sequence, how to consolidate them, what student notes might look like, check-your-understanding questions you can use, as well as notes from Peter Liljedahl and Kyle Webb. It’s a wonderful compliment to the main BTC book.
