Trig Functions: Desmos

As always, I was able to knock this lesson out of the park... thanks to Desmos!  It is so easy to check the students' progress through the teacher dashboard.  And if you want, you can project this screen so that students can see if they are correct with their card sorts.  What was my teaching life like before Desmos?  Not like this!

Because I do so many activities in class, my students have gotten in the habit of asking, "What are we going to do today?".  And not in the annoying teenage/eye-roll fashion, but in the I'm pretty excited about coming to math class fashion.  But they weren't always this way.  Trust me, I begin on day 1 doing some sort of an activity in all of my classes.  I want them to know that I expect all students to be engaged 100% during class time.  Unfortunately, most of my learners did not get this excitement (that's what I'm calling it anyway) in their previous math classes.  

Back to today... my Desmos activity.  I created this based solely on graphing trig functions with a unit circle review tucked in at the end.  The trig functions do not have phase shift included- that is saved for Math 4, but include amplitude, period, and vertical shift.

The students had a great time completing this task!  I had them paired up, but they were not limited to discussion with only their partner.  Students could help peers in other groups; and they did.  It was amazing to watch the community of learners have rich conversations about math 😊

I hope your students have as much fun as mine did!

AP Calculus Hunger Games Review

I created this a couple of years ago when Hunger Games was really popular. However, I thought that I would share with all of you in case you wanted to use or revamp to something newer.  I created 12 groups for the 12 districts. They decided what their name would be as a district. They had tasks each day to accomplish. The tasks were just multiple choice questions centered around the major topics of Calculus AB. This took a lot longer than I thought - about 4 days. I was forced to give them more than 15 minutes for each task (which did not make me happy since the AP exam is timed - Oh well.) I had the time, and it worked out.  You can decide how you want to the points to work, I gave them 2 points for each correct answer. It was very easy to grade as this is the student worksheet. They placed the letter of the answer in each spot.  I made them show all work on another student sheet so that I could see what we needed to review.  Each day, I would post the new rankin

Exponential Growth & Decay Scavenger Hunt

Scavenger Hunts are always fun (and easy to grade). This particular one is all about applications of exponential growth & decay. My students seem to understand this topic really well, but I still wanted to provide more practice.  When I did this hunt originally, I created the cards with the answer on the front and the question on the back. Once I figured out how to copy and make it work, it was great because I could use the cards over and over again. However, they started looking old, and I lost some of the cards. So t his year, I placed the answer and question on the front. It made it so much easier to copy!  If you would like to try this in your class, here is a copy ! I included the solutions as well.  UPDATE: I created this activity and transformed into a remote version.  Remote Version: SE Scavenger Hunt               TE Scavenger Hunt ~RJ

Adding & Subtracting Rational Expressions Drag & Drop

Because Math 3 now has drag & drop on the final exam, students need the practice. So, I created one using Google Slides. It went over really well!  While this only took the students about 40-45 minutes to complete, it took me about 2 days to create this activity. Oh well, at least it is cute! :) I used Google Drawings to create the scene and took a screenshot of the drawing to post as the background in Google Slides. This worked so that students could only move the answers.  I created this for an Honors class and one of the problems (#5 - the one pictured) really stumped the kiddos. I loved it! They kept thinking that x - 1 was not part of the common denominator...they didn't realize that they needed to simplify after subtracting. It really made them think!   When they were finished, they shared it with me! I really think that this helped the kids get more practice on drag & drop while working on adding and subtracting rational expressions!  Here is the ac
