Normal Curve Practice: Matching

Someone bequeathed unto me this activity years ago - I hate that I cannot remember who, but let's be honest - I'm lucky I remembered my pants this morning 😀.  

 Because this activity was shared with me so long ago, I had to convert it to a Google Doc and the formatting may be slightly off.  Feel free to make a copy here and edit it yourself to make it perfect for you!

 Here's the gist: students are given a pack of cards.  There are Normal distribution situations on one side and answers on the other.  Begin by mixing the cards (in case the previous class left them in order 😨) and placing them all answer-side up.  Students will turn over one card, complete the task, find the answer on another card, turn over that card, and repeat.  Clearly, if done correctly, students will end on the first card they chose. This is great in that students will immediately know if they are right or wrong - without me giving them feedback.  They work in pairs to solve these questions and talk through any issues.  Of course, I circulate for the duration and make sure all students are good to go!

 The drawback? you may ask... This activity is strictly procedural.  It is not what I would expect on my assessments, nor what the AP Exam will accept ("bald" or "naked" answers).  But you may notice, the students were drawing their Normal curves and shading the appropriate area (a requirement from me).  What was missing is the context in the responses - but if the answers had context this would not be a very challenging activity!  However, this activity truly helps the students recognize when to use the normal CDF vs. the inverse normal distribution.

 Good luck and thanks to that wonderful educator who shared this with me!

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

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 ...

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!...
