For the fast kids, create your lessons with extensions. You can google it for more details on how to do this skillfully, but an extension is basically building something extra onto your first task. Note that good extensions are not busy work -- they typically either lead to the creation of a cool product or they introduce a new and related concept. Either way, good extensions are ones that motivate the middle kids to try to get to the extensions phase. For the extra-help kids, the best thing to do during class is to have them work with a friend who got it. Sometimes their peers can communicate the key ideas better than you can. After the class, you can review the problematic ideas with them and/or give them extra problems for them to work on (if they are interested). You will win them over if you can review those extra problems with them at a later time (e.g., before the next class).
