Speed Dating: Right Triangle Applications

I previously did a speed dating activity with solving exponential and logarithmic equations. I really liked how students were teaching each other. So I decided to try it again with solving right triangle trig applications.

For this activity, I didn't have an application problem per person, instead per group. In groups of 2-3, students had to answer the card given to them. Then had to move to another group - switch cards and answer the question.

I assigned roles to each member, but to hold each student accountable, when they switched the roles also switched. (In groups of three - here are the roles: an encourager, a recorder, and a checker.) The encourager had to use probing questions to help facilitate the other group if struggling, the recorder had to write down the work, and the checker had to look over the work before they could move on.

I ordered some buzzers from Amazon, and loved being able to push them to make the groups switch. (That's one thing that was missing in my last speed dating activity.)

I created QR codes for the answer and placed them on the back of the cards. This only gives the first group a chance to check their answer before moving on to speed dating. I still required that the student worksheet be completed and all work shown in order to receive credit.

From this experience, I think that speed dating works best when each student has a problem to solve. Since there were so many students in a group, they didn't really have places to sit and it became a big mess. So next time (since I already have the cards made) I'll just make it a gallery walk, where students must move to each station answering the questions.

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!
