Skittles & Measures of Center

I'm pretty sure you have seen this activity before! It's nothing new. However, I gave it an updated spin using Google Suite. 

I created a HyperDoc where students read an article and collaborate to complete a Google Sheet. The article claims that there are more yellow skittles in each package. Well, we all know, since it is on the internet - it's true. 😂 

Well, we decided to do our own experiment. I did spend some $ on this activity, but I ordered the skittles from Amazon, and feel that I saved some money that way. 

I would typically do this in groups of 2, but I have a small class this year, and I wanted more data. I had each student count the number of red, yellow, green, purple, and orange skittles in each bag. I shared the Google Sheet so that each student could edit, and they typed in the data from their bag. I love using Google as a collaboration tool. 



Once all students were finished, I had them go back to the Google Doc and complete the table using the class data. I didn't tell them at first how Google Sheets could do all of these calculations. After the first color, one student was on a mission to figure out a better way - and used Google search!  

I know that this lesson is about the students calculating mean, median, and mode, but I feel like being able to use technology is just as important. Other students started to catch on, and finally the class was utilizing the explore tool in Google Sheets. I was so proud! (From formative assessment early this morning, I knew that all students were masters at measures of central tendency, so this didn't bother me!) 

Using the data, the students answered questions on the HyperDoc and shared their copy with me. The class data showed that out of our batch of skittles - there were more orange skittles! This brings up a great discussion - is this always true? Does it have anything to do with our sample? What could we have done differently? What does the mean tell us about our data? Overall, I would say that it was a great lesson.

Polynomial Picture Project

Projects allow the students to show off their creativity and math skills! This one requires students to use Desmos to help create a polynomial function that fits a picture of their choice. As you can see with some of the projects below - the ideas vary immensely. Some of the students are very clever and others just use the McDonald's sign. However, each year, the students amaze us at what they find.  Instead of using their calculators - here's how Desmos will find the regression line. In my video, I just did a simple quadratic, but our students have to create a regression equation that requires at least 3 relative extrema.  Typically, we show the students how to use the Desmos regression option before sharing the project. Some students have trouble fitting the graphs because they choose too many points, and others are upset that it doesn't fit perfectly! We reassure our students that this is the best fit - not a perfect fit.  Once students have the reg...

Limit Project

Well...we just got back into school after being out for almost 3 weeks because of hurricane Florence. Our school is okay, but there are many people out there suffering from losing so much. :(  I had planned on a project for Calculus before the storm but will have to put that aside until next year! We have just lost too much time. However, I wanted to still share the project with you guys in case you would like to try it or something similar to it.   I like to make projects a unique experience. I hate when all students do the same thing. #1 - students can and WILL copy. #2 - It's boring to grade!  The idea of this project is floating somewhere on the web. I honestly can't remember where I got the idea. But I have altered it over the years to meet the needs of my students. It has gone through many alterations, and I will continue to change things.  So it is not perfect!  The gist - students find a recipe that has at least 5 ingredients. (The recipe ...

Arithmetic & Geometric Recursive Investigation

Investigation and student accountability is extremely important in education today. Students need to be challenged! They will learn so much more by discovering the formulas rather than me just placing the formula on the board!  While talking to my intern about not finding anything cool dealing with recursive sequences, I got an idea. I wanted my kids to find a pattern and develop the arithmetic and geometric recursive formulas using the information that they already know.  I created a cut and paste activity where students had to match the sequence, the type, the common difference/ratio, the explicit formula, and the recursive formula. From that, I hoped that students would be able to see a pattern! On a note card, I had them answer three questions...describe any patterns that you see, write a general recursive arithmetic formula, and write a general recursive geometric formula.   The students did an awesome job until they were asked to produce the general rec...
