Why Should I Absolutely Use a Warm Up or Bellwork?

Sometimes you hear people saying that the purpose of warm-ups or bellwork is just to get kids settled at the start of class, and give the teacher time to get settled.  

That may be true, but I don't see that as the main purpose of a warm-up.



In my classroom, a warm up or bellwork is a key part of instruction.  I use them as daily quizzes, worth 2 points each day.  At the end of the week they get added up for a ten point quiz grade.  They are graded 2 points if correct, 1 point if tried but partially correct, and 0 points if not tried. I used to actually grade them for correctness, but I really want the students to try, even if they are unsure, and they will get 1 point for trying.  I want to use bellwork more as formative assessment than summative.

I use the same sheet each day for each student.  They know the routine to pick up their bellwork paper on the way into class.  This helps me with attendance, as well, because all students who are present on time pick up their papers.  Those papers left are absent.  When bellwork is over (first 5 minutes), collect their papers and grade them for the next day.  It sounds time consuming, but it only takes me a few minutes each day to go through and mark a 0, 1, or 2 on each student's bellwork square for that day.  It also gives me an excellent gauge on their comprehension as we progress through the unit.

You can see the bellwork sheets that I use on a weekly basis here. This really saves me time at the copier!  Instead of copying daily bellwork, I copy once a month and then put the bellwork on the board or smartboard when they come in. They just record their answers in the daily box.

Bellwork or Daily Quiz Template

I choose the questions that I use for bellwork very carefully.

At the start of the unit, I make bellwork very open-ended.  Some examples are interpreting a diagram, or making observations about a diagram.  I have also had bellwork early in the unit that focuses on a small reading passage, a connection between last unit and the new content, or even listening to a song or watching a video and stating what they think it is about.

I also like to use bellwork to build prior knowledge, if possible, or to practice basic skills, such as determining what is wrong with a graph, or to learn new vocabulary.

As the unit progresses, I ask content based questions, usually from what we just did yesterday.  This is where bellwork holds them accountable for yesterday's work, gives them a heads-up if they were absent, and gives me a quick look at understanding from yesterday.  At this stage in the unit, I usually use concept-based questions, but write them in my own words, or in more student friendly language, although I may use some diagrams from state exam questions.

As we get closer to finishing up a unit, my bellwork will mostly consist of state test questions on the topic that we are studying.  This is where they really get used to the language of the exam, and apply what they have used.

Lastly, depending on the group of students that I have, I sometimes do bellwork in a different way.  I teach in an urban district where reading levels are very low.  There have also been years where I have had a lot of ELL's.  Many times they are struggling with not only unit concepts and vocabulary, but tier 2 vocabulary, which we don't traditionally teach in science class.  I have used bellwork as a chance to teach some of these tier 2 vocabulary words, using this products in my store.  These give students pictures of a word, and ask them to infer the meaning.  We worked on 4 or 5 words a week, and then had a quiz at the end of the week.  This really helped, and made students more confident with inferring meanings of unknown words as well.

Teacher Life Hack - Easily Maintain your Sanity

I don’t know about you, but I am constantly seeking a better work-life balance.  Teaching is one of the jobs that can easily take over your life, if you allow it to do so.  There are a lot of things that I do to maintain a work-life balance.  Many of them revolve around food prep.  I previously wrote a blog post here that touches on that.  


During the school year, no matter how much prep I do, it is hard to maintain a balance during the year.  One thing I do to try to maintain some kind of balance is take my work email off of my phone!  I especially do this on the long weekends, or over a school break.


If you aren’t ready for that step, then at least turn of the ‘push’ and the notifications, so you can check it on your schedule!


Another option would be to put it under a separate email app so that you have to choose to check it, on your schedule.


When work email is on your phone, it is too easy to feel an obligation to answer emails at all or hours, or to read an email that makes you frustrated or upset when you should be getting ready for bed, or enjoying family time.

Nightmare with Multiple Labs? Make it Immediately Manageable!

Are you feeling overwhelmed by multiple preps, particularly multiple labs to set up?  That can be mind boggling at first, but it is manageable, I promise you.  I've been there.  Teahcing lab sciences, particularly to middle school students adds another layer of complexity.  Here are a few tips...


  1. If you can, stagger that days when your classes have labs, so that you don't have to set up too many labs on the same day.  I know it sounds great to do labs when they fit into the curriculum, but most of the time you can make it work.  It is better for the students to have you be able to do it calmly than to be stressed out by trying to do a lab one day earlier or later.  For example, maybe you do Biology labs Monday and Earth Science labs Tuesday.  If you can't always structure it that much, at least try to have them fall on different days. 
  2. If possible, maybe you can correlate the classes.  For example, if one is an honors class, and one is a lower level class, maybe they can do different versions of the same lab.  The set up might be the same, or similar, but you might ask for different analysis questions or more detail on their write ups.  Maybe one is conceptual and one is quantitative.  This can only work depending on the classes you have, but its worth mentioning.  Really saved me when I had 5 lab science preps as a new teacher!
  3. If you can't, or you have labs that go more than one day, train your students, and use their help.  The best way I have found to do that is to have the materials out in bins (dollar store dishpans work well) for one per table.  You can set them up ahead of time, and they can quickly grab their materials, and put them back into the bin when they are done.  You can either pass out one bin per table, or have them set up in one consistent spot where students can get their supplies. 
  4. Another option that I have seen to is to have one counter where students from each lab group come through like an assembly line and get their materials.
  5. Leave a few minutes at the end of class for them to clean up. It seems like you want them to finish, but, I promise, it is worth training them and leaving them a few minutes to clean up.  Make sure they do it before they leave and you will save your sanity. 
  6. If you have to leave a lab out, have a designated place for them to put their materials.  Don't less class end, and you and they are fumbling for where to put their things.  If you have multiple preps, make those spots different and designated for each class.  For example, maybe one class always leaves their things on the windowsill, and another class always leaves their things on a back counter or extra table.  This will eliminate a lot of confusion.  They know they shouldn't be touching materials belonging to the other class.
