Brain Work is a great homework assignment or review for your class. I used them as a nightly assignment as we approached the test. It is a MIXED review and touches on all of the TEKS with an emphasis on READINESS TEKS.
The answers are open ended and lead to great discussions. When students bring in the assignment, I would often let them compare their answer choices with a partner.
I use the COLOR version from the PDF file on my projector when we would discuss as a class.
Because the questions are short and contain MANY pictures, students felt like this was a very 'doable' assignment.
