Right Triangle Trig: Scavenger Hunt

SOHCAHTOA... so many ways to teach our students to remember this. Personally, I've never been comfortable with the "hippie" story and I know there are others (here is a site dedicated to mnemonics) out there like this story of the Legend. But luckily, RJ and I teach Pre-Calculus so the kiddos come to us (hopefully) already knowing the basics - we get to take their knowledge and turn it into application!

For this activity, we pulled together 12 of our favorite right triangle application problems - some we made up and others have been around for ages. We put answers on one side and the questions on the other. We even put the questions upside-down so that the students could just flip the card up and not have to take it off the wall. The cherubs are in groups of 3 and begin at any numbered card. They flip the card, complete the task, and then find the numbered card with that answer. Repeat.

As with all classroom scavenger hunts, there are many pros!

Students are engaged
Students are taking control of their learning
Students get immediate feedback since they know right away if they have a correct (or incorrect) answer
Student-led discourse is way more meaningful than teacher-led discussion
Teachers get their steps in walking around

Of course there are drawbacks...

Creating activities can be time consuming
Teachers cannot just do one activity a year and expect the students to handle themselves appropriately
It was very confusing trying to make upside-down copies on the back. I'm embarrassed to admit that it took several trials/prints.

Here is a copy of our Triangle Trig Scavenger Hunt. Enjoy!

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

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

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
