Flip Book - Middle School Math Project

Ok so flip, turn, slide or reflection, rotation, translation can be one of those items that gets skipped when other items take a bit longer.   It is one of those things that seems to be put on the backburner.  Well I started doing this project part way through the year to make sure it wouldn't get missed.  We start just after integers and begin learning about the Cartesian Plane and coordinate systems.  This then lends itself to the transformations that can occur on the plane.  I have had a lot of success with the flip book by have students create motion with their transformations.  I have the students work on how to rotate and translate as well as reflect.  Rotations need to start with easy 90 degrees, 180 degrees or 270 degrees.  More advances students can start trying other degrees but they usually have some difficulty with it.

Here are the sheets in one file:  Flipbook project sheets on my TPT site if you dont want to just recreate from this page.

Have the students use very simple characters or elements of nature.  Stick men running or the sun setting are just fine to start especially in the rough copy version.  Simple movements end up looking better in a flipbook.  I have had boats moving into the sunset and people on trampolines as easy examples.

Smarties / Skittles - Data Analysis and Graphing Project


This idea didn't come from me.  It has been borrowed from a teacher I worked with years ago.  I took her idea and changed it a bit.  I have also adapted it based on whatever I want to teach that year, which makes it great. 

So even though this project may be difficult to connect to the real world and the question math teacher get the most "Why are we doing this", it is a lot of fun for the students.  Yes , it is based on candy which immediately gets their attention. 

I have used this to teach bar graphs, circle graphs, central tendenciesExcel, theoretical and experimental probability and even stem and leaf plots. The kids really seem to enjoy it and are generally interested in the results.

Here are the basics - bring in a box of Smarties or a bag of skittles.  Some students bring in huge family size bags but only an individual package is necessary.  There job is to graph the different colours that occur in the candy package.  Using probability I will ask them the chances of reaching in and grabbing a red one.  Or have them experiment on how often a red one comes out.  Yes it is silly but the kids get into it and learn because of the candy.  The display that they put together will have four graphs. The graphs open up and underneath the student explains the style of graph on top.  The can explain the data or explain the purpose of that style of graph. 

Examples:  I have done this a few times and so there are different styles here

Investing in the Stock Market - Middle School Math Project

This year I finally went for it and jumped into the stock market.  I know nothing about the stock market and so I told my students I wanted to learn.  We made a project out of it and after consulting friends about how to start we went for the competitve option.  The students had no idea about investing or business so we started by bringing in a guest speaker who talked about what people think about when they are going to invest.  The speaker was actually just a parent of a student in the class and she gave some excellent background information.

At the time we were also learning about integers and graphing and took some time with the students who already had demonstrated that they understood those concepts and brought them to the computer lab to begin researching websites, key terms and tips on how to invest.  They basically became the investment "experts" in our class.  After the others completed their math work on integers we had all the students enter the computer lab and paired them up with the experts.  Students then began teaching students on how to invest.  It was a very good starting point.

I had all the students join onto www.howthemarketworks.com which allowed them to not have to give away personal information.  They all practiced how to buy stocks and about the rise and fall of the market. 

Through the website I started a contest for the class where they got $10,000 and could invest it however then wanted with the restrictions of the contest and my own criteria where must have bought stocks in at least 3 different companies. 

And it was on!  Students were checking there stocks constantly, at nutrition break and lunch times you could hear students talking about their investments.  We continued going to the computer lab to do more research and students were eager to see how they could make more money.  I included at $5 dollar transaction fee and the students were angry with me because they thought it unfair but I told them that we are trying to make it as real as we could.  Some students held onto investments while others became  day traders and were constantly updating their account.  It was pretty cool to watch students so eager.  Some of the students were quite funny in that they were refreshing their portfolio every couple of minutes for the update of their account. 

The students learned about graphing, net gain and loss, percent gain and loss, and how hard it is to make money on the stock market.  Some students learned that you have to spend money to make it as they had $10,000 but only spent a small portion of it and couldn't keep up with the others.  Some spent all the money on some big name companies while others threw darts.  It was very interesting but in the end the one who did the most research actually made the most by investing in companies that were trending up as well as short selling stocks too.  In a month she made over $1500 which was pretty impressive.

Here is the criteria I gave them, please post comments on how it worked for you or if you changed what I did.  I would love to know.
