To add to the previous posters discussion. Once you know the areas of concern by looking at the reports on the NWEA site, you can use that information to find some great activities at the following site:
We have a weekly academic tutorial where we are supposed to work in small groups with students who did not do well on the MAP. I just use the reports and pull a group of students from that, then I pick one of the activities to work on the students with. A lot of them are center ideas so they are hands on, and can be used with a small group easily.
