I found one that shows the graph of the inverse of sin. I thought it was really cool to use to show students how they are different, as well as what point is the inverse at when on the sin function. Another one I found is dealing with tangents to a circle, it shows what […]
I found some cool applets about polar coordinates, probability (spinner), and triangle properties. I’m most interested in learning how the triangle applet works.
One of the ways math teachers use computers to help them teach, is to use computers to provide animated visualization tools to convey important concepts. You saw that with the parabola with sliders you created last class. Besides using sliders to make instantly changing graphs to help students understand the effects of different terms in […]
I found a new collection of applets, so I thought I’d better save the link somewhere. Here it is (SLU was new to me) along with a bunch of other sites that might (or might not) be new to you. NLVM Wisweb Manipula math SLU applets Interactivate MNWest Geogebra Applets

Today we are learning how to use some of the features in Fathom. For our turn-in assignment on Fathom, you’ll be importing some data from Excel, and using Fathom to fit a line or curve to help analyze the data. This is my box folder where the data is that we’ll be using.
I found a couple interesting lesson plans for sixth grade. They make good use of a spreadsheet program to help students visualize divisibility patterns. The Divisibility lesson plan and the student worksheet are simple, but could be expanded for use with higher grade levels. The same teacher also created a lesson plan for finding Least […]
Got to the Peanut Software page and download Winplot. Install (unzip) it onto the desktop if you are in the lab (if it’s your home computer, of course, you can install it wherever you wish). You can make 2D graphs of equations (Equa), and set the color and pen width however you want it to […]
This Lesson is extremely interesting, it also does a good job in helping students deal with money on their own. This is directed towards Seniors, and the chalkboard does not do anything like what Excel does, it also gives the students a way to organize their data from running their particular stand. It also gives […]
I ended up looking at quite a few different lesson plans using excel. Here are three that I thought were interesting and what I liked about them.
