I am doing a before school Math intervention with about 15 upper elementary students. I am curious if you were given that opportunity, what would you focus on? Would you do only what the students are working on (struggling with) in class? Go back and reteach things they have missed in the past? I am trying to do a bit of both but would love ideas if you have some to share. I do have computers available to all of them so that can be helpful.
