We used Google Classroom to distribute the math slides files.
Students and teachers also used the comment feature on google slides to discuss their thinking. We loved projecting the math problems and strategies. Even if students got the answer incorrect, they loved discussing the process and finding where they went wrong.
This used several of the Math Practice Standards, but especially Standard #3 Construct viable arguments and critique the reasoning of others.
