I have been hired to serve as the sole teacher of a 1-8 private school. My concern is this: Though the younger students will probably get most of my attention, I will of course have to work with the older ones, too. How can I keep second graders occupied with independent work while I focus on other grade levels? I'm thinking about learning centers, but I want them to actually be LEARNING at these centers, not just playing. Any ideas for how I can keep kids with minimal reading skills engaged in learning on their own? Any good books or websites on the topic would be helpful, as well.
