Triangle Trig Project

I needed one more project for the semester, and I wanted the students to be able to move around. They sit for way too long!

I remembered seeing an activity that required students to search the school and take pictures of triangles. Well, I thought that could make for a good project! In groups of four, the students used one iPad and were sent out on a mission - find objects in the shape of a right and oblique triangles.

I thought that groups of 4 would be too big for the presentation portion, so I divided up the big group into pairs once they were back in the classroom.

For the right triangle, students were required to find one angle and one side, and for the oblique, they had to start off with finding one angle and two sides.

As for the sides, I wanted to make it a little fun! I sent each group a different emoji to act as the scale instead of using a ruler. (I created a Google Form that students filled out once they returned. The form asked for their email and group member names. The form spreadsheet allowed me to easily copy paste their email address and send their particular emoji from my teacher version.)

Here is an example of one group that had to use the bathtubs:

For the angle, students found a protractor online and placed that as an overlay on only ONE angle. (On a side note - I like to have transparent protractors - so one of my students taught me to google protractor png. Works like a charm.)

Using the emoji scale and the angle, students were required to solve the triangles, answer some questions, and make the presentation pretty.

This went over way better than I could have imagined. The students loved being able to leave the room and were on task when they returned. I'm finally comfortable with letting my students roam the school. A few years ago, I'm not sure that I would have allowed this to happen. It's hard giving up control. It feels great to start trusting my students more - and I think that they appreciate it too!

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
