## Free Open Reference Interactive Geometry Book

Check out this website I found at mathopenref.com I will definitely be using some of the applets here the next time that I teach geometry as part of a pre-algebra course. In fact, maybe I'll have the students read through this and play with all of the applets as part of their homework (before) coming to class. ...

## New Slope Game

I hope you enjoy this game!  I would love to have any feedback if you decide to use it. Slope game Other Slope Resources Applets 1.  Interactive Slope Applet - Although I ran out of time to actually use this with my own class, this is a wonderful resource that lets students click and drag points such that when the line between the point changes, the calculation of the slope of the line also changes on the screen as well.  Very useful! 2.  Slope-Intercept Equation Applet - This appears to be the exact same applet I introduced to you a few weeks ago in the Geogebra Tutorial video.  It's a very simple resource that allows students to visualize the slope-intercept equation of a line by using sliders to change the slope and y-intercept. Worksheets 1.  Pete Falzone's Understanding Slope and Y-Intercepts 1 2.  Pete Falzone's Understanding Slope and Y-Intercepts 3 3.  Pete Falzone's Graphing and Using Slope and Y-Intercepts 1...

## Statistics Resources from Across the Web

I'm preparing to teach statistics this summer, so statistics resources are on my radar right now.  Here are some that have been fed to me recently: 1.  Prezi on 'Beyond Tables' -- Awesome Prezi on ditching the tables and integrating applets such as those over at Surf Stat.   Beyond Tables on Prezi 2.  YouTube Video - "Benford's Law -- How Mathematics Can Detect Fraud!"  -- I wanted to teach Benford's Law better the last time I taught statistics, but I didn't know how.  This will help. 3.  10 Jaw-Droppingly Awesome Infographics on Education -- If you didn't see my spiel on Infographics from the last time I taught statistics, I would definitely plan using this assignment again in the future.  This is just one more example of why -- Infographics are just so awesome! http://blog.socrato.com/10-jaw-droppingly-awesome-infographics-on-education/ 4.  Chi-Square Goodness of Fit Resources -- Some highlights of a recent web search I did on the topic. http://www.cod.edu/people/faculty/fancher/Bio101/ChiSquare.doc http://www.jmap.org/JMAP/SupportFiles/Amsco_Textbooks/Algebra_2_and_Trigonometry/Enrichment_Activities/AT16-3_Chi-square_Test_for_Goodness_of_Fit.pdf http://homepage.mac.com/bradthiessen/stats/m301/11.pdf ...

## Interactive Demonstration Tools

Here are a few highlights of some of the Interactive Demonstration Tools that I have come across in the past few weeks:1.  All Interactive Whiteboard Resources - Although the applets on this website are designed to be friendly for those classrooms with Smartboards and the like, I see no reason why these applets can't be used in any classroom.  In fact, I plan on use this Angle Measure resource when teaching my classes about angles in the upcoming weeks.  Other great resources on this website include this Translation Plotter, which helps students to visualize translating a shape in the Rectangular Coordinate System.2.  Interactive Slope Applet - Although I ran out of time to actually use this with my own class, this is a wonderful resource that lets students click and drag points such that when the line between the point changes, the calculation of the slope of the line also changes on the screen as well.  Very useful!...

## GeoGebra and Applets for Calculus

Somethings I have learned just by being a little more observant.  One day last week I was sitting at a different table than usual at school, and it happened to be next to the bulletin board.  At the very top of the bulletin board was a flier that I had never seen before that had a list of two websites, one of them being Math Applets for Calculus at St. Louis University.  Personally, I have never been too big of a fan of applets, but most of these are really great.  There are four types of applets there: JCM Applets, Banchoff Applets, Geometer's Sketchpad Applets, GeoGebra Applets. However, I was actually more interested in GeoGebra than the actual applets, since I had never heard of it before.  It turns out that GeoGebra is a free tool to create learning and teaching materials.  I played a little bit with the web-based version since I didn't really want...
