A semester's worth of bell ringer activities and topics! My students use my Bell Ringer pages (pasted into their interactive notebooks). On Monday they write down and try to answer a riddle. On Tuesday they have a writing topic or question to repond to. Wednesday I write a short poem on the board and they write it down, starting a conversation about the poem and its meaning. Thursday is Research Day, they use the random button on Wikipedia and write about what they learn.
These are a great way to eat up time while you take roll and attend to things at the top of class, warm up your students, to start a conversation, and to get some insight into your students.
I also include this calendar (with our daily assignments and topics) on One Note for students to access when they miss a day. I have included my school's holidays, so you may want to restructure as you see fit!
