I regularly assign Khan Academy for my class on days when they have a math test. It gives them work that is pushing toward a goal without giving them a free night with standardized testing approaching. However, this round when I went to check it, I was met with groans and protests that they had done the work, but it wasn't showing up on the activity page. Has anyone else experienced this? Could there be an error in the program or was it that the students weren't being truthful?
How can we help?
