Probability Wars - A Deck.Toys Review

I love Star Wars! Since the last movie is coming out soon, I thought I would create a Probability Wars Review using Deck.Toys.  I love using Deck.Toys as a test review. It allows me to keep track of their progress, and my students would rather do this activity then a worksheet.  I found a site where you could create your own Star Wars opening ...of course, I had to do that! :) I also created a quest for each main topic we discussed in class. (Mutually Exclusive/Inclusive, Independent events, Binomial, Permutations, Combinations, Counting Principles, and Normal Distribution.)  I didn't use any study sets for this particular activity. I utilized the Lock app for each question. I decided to use this because I noticed some students guessing on multiple choice to get done with the activity faster. With the Lock app, students had to answer correctly to move on to the next question. I could also easily see where students were struggling by watching the teacher page!...

CLT: An ACTivity

I always find myself needing fresh ideas. Thankfully, Stats Medic was here to help... again! The CLT is not a terribly hard concept for students to memorize, but do they truly understand it?  For this ACTivity, students are comparing the ACT scores (get it now? ACT ivity?) from two high schools: one has an approximately Normal distribution while the other distribution is clearly skewed right. Students are taken to an applet where simulations are performed on the two distinct distributions, they are instructed to take samples of different sizes and then to describe/compare the sampling distributions. After the activity, there is an example problem to check for understanding. A couple of notes: While the resources on Stats Medic are fantastic, it's not very pretty (IMHO). Therefore, I have prettified it. Instead of using paper/pencil worksheet, I did create a HyperDoc for the students. Thanks for reading! Student HyperDoc Teacher Solutions ~ssb

Histograms, Box Plots, and Measures of Center & Spread

Our school has made the jump to online testing! So you know what that means...DESMOS!  I wanted to show the students how Desmos could create histograms and box plots. Then I got the idea to allow students to find the mean, median, and standard deviation too.  So I created this Desmos activity as a tutorial & practice for those topics. The activity ends with a card sort where they must match the  mean, median and standard deviation to a histogram and box plot. I also included some multiple choice and open ended questions just as a review. I allowed them to use the Desmos calculator to assist in answering the questions.  I will say that my students aren't making the jump to Desmos so easily. They still can't let the handheld calculator go...but at least I'm trying!  Here is the activity if you would like to try this out in your classroom: Activity   ~RJ
