Bell work... Bell ringers... Do-nows... Warm ups. Whatever you call them, it is important to have some sort of routine at the beginning of the class period. Your day will run so much smoother when students walk into class and know what to begin working on without being told.
I love using daily bell work assignments because:
Here are some ideas on what you can use for bellwork.
Some teachers like to do the same type of bellwork every day and others like to vary it Monday-Friday. Do what works for you!
How you decide to grade bellwork is completely up to you (and will depend on the activity). I tend to stamp for completion each day, turn in on Fridays, and add up the stamps for credit. It's easy points- all students have to do is show up and give effort. Whatever method you choose- don't create a bunch of work for yourself. You have enough to grade without the added stress of bellwork.
I hope you find a few of those ideas useful!
