Hello I am interested in using daily (or almost daily) mental math activities in my high school math classroom, but I'm unsure of how to do so. I have used this in grade 8 by having the mental math be on a powerpoint and the students had ten questions each day. After the questions were posted (with a time limit for each one) the answers would go up and students would self correct. We (my coop teacher and I) couldn't really asses the mental math this way but we were able to see how the students were doing and developing. I am thinking to employ something similar in my class, but I need to have more ability to asses it. Any techniques that work for you? Thanks!
