An easy way to make bell work simple is to have transparencies all ready ahead of time. Every time you use bell work or come across a good idea, jot it down. Take a few hours on the weekend and make all of your ideas into transparencies. Make sure to write all necessary instructions on these as well so that the activities can be completed independent. Keep all of these in a mini-file box. Every morning you can just pull one out and put it on the overhead for the morning activity. You eventually may want to organize your bellwork box into subjects to make sure your class gets a variety everyday.
