20 Things to Do Before the New School Year: BTS Checklist

It’s that time of year again…you’ve had a bit of a break and now your mind is going wild with ideas for the new school year.   To keep your time and efforts focused (and your stress levels down), I’ve created a list of 20 things to do to prepare for the new school year.

6 Things You Can Do to Stop Wasting Your Own Time in the Classroom

If you’re looking to regain some of your essential time, this is a post for you!  Many of the daily systems teachers have setup for themselves and students can quickly turn into time-sucks.  Now, I’m not talking about the ever-important relationship building part of teaching, but the nitty-gritty paper passing out, finding absent work, and making seating charts side of things.   I’ve found a few ways to streamline my routines and classroom practices so that I can stop wasting my own time by being inefficient.  Here’s my tips for you:

My school doesn’t cover interval notation in its curriculum.  We focus primarily on inequality notation, although I tend to use the more specific set-builder notation.  Each representation has its merits, so I wanted to include interval notation more this year, as an occasional aside.  I’ve made a poster (8.5×14) that I’m going to hang up in my room to help students see the connections between the inequality symbols, the choice of open/closed points on a number-line, and the choice of soft/hard brackets in the interval notation. I’ve also made a color-coded version where students can ask themselves, “Can I include this point?” Green=”yes, include”, and red=”no, exclude.” Half of my classes this year are geared toward students who had received <40% in their last math class, so I’m hoping that the stop-light colors can make this yes/no, include/exclude concept easier to grasp. [NOTE: Thanks to lovely conversations on Twitter, it’s been noted that the green/red combination could potentially be dangerous if you have any colorblind students! I’m working on another, more color-friendly version that you can use, as well. I will update this post when it’s been made!]

Before I hang the laminated poster up (I add posters throughout the year as topics arise), I’m going to print another one and cut up the grid into the 36 individual rectangles and hand one piece to each student in my class (if there are fewer students, ask your class “who wants another piece?”–I always seem to have a bunch of volunteers because this means they’ll get to talk to more people!).  Students will then find the two other classmates who have representations equivalent to their own card. Once a triple has been found, students will check their cards with the teacher.  If they are correct, they will move around the class helping the remaining students.  If they are incorrect, they will review which card(s) in their triple didn’t belong as a group of three, and then go back to finding the equivalent representations.

Would you like a copy of the reference poster? Get the color and the black and white versions here! (It’s free!)

A while back I made a display for special right triangles, and realized I never shared the files! You can download the PDF and the editable Publisher files here!  You’ll need to download the free font HVD Comic Serif Pro if you choose to edit the Publisher file yourself.

Here’s a picture of the pre-laminated pieces.  I took a few pieces of the finished product on my walls in the classroom, but each one had a nasty glare from the laminated finish.

Throughout the year, I will be adding more justifications as they come along.  The next batch that we will come across will be about segments.  From there, we’ll talk about angles, congruence, similarity, and more!

Here’s what I’ve got so far!  What justifications you most want to include in an edited list? I plan on using these primarily for two-column proofs in geometry.
