Interactive Simulations - Math and Science

http://phet.colorado.edu/en/simulations/index
Clicking on the above link will take you to a page with many different simulations. They are all relatively small programs that can be downloaded to your computer. You do not have to have access to the computer to run them although you can choose to just use them from the web. Magnetism, electricity and math are a few of the subjects that are covered. There are over 80 different sims and you owe it to yourself to check them out. They are great for exploration or review of topics.

Great Source for Math Games

I found this site I Play Mathgames.com and thought it was something that teachers might want to know about. All of the games are in .pdf format, they are not computer games, but the site has a well organized way to find good paper games to play with the students. These games are all from different types of workbooks that could be purchased, but I think that there are enough games on the site to make it worth your while to check it out!

Good Math Tool - Geogebra

I was hunting for new programs for the school year and came across Geogebra. It has apparently been around for a long time as it has won many awards, but this was the first time I have ever heard of it.
It is available for download on your computer for Windows, Macs and Linux. It has a great web site that accompanies it to show all the ways that you can use this program in your math classes. You can use it to show how to do something as similar as perimeters and area. (This is probably the main way I will use it.) Students can "play" with the graphs to see how changing the shape will impact the area and perimeter. You can also do much more, such as showing complex math formulas or playing with a Kaleidoscope in Geogebra. There are many examples from elementary school to college. I recommend you take a minute and download the program just to see what a good FREE program could do for your understanding of math.

Numbers Web Site - A break from Open Office/Word

I just found this site all about numbers. It has a lot of information in it, a good place for students to have a math dictionary with places to practice their math and it is able to be downloaded and placed on a computer so you are not dependent on a good internet connection. Numbers has many good features. If you are working on teaching students pictograms, you can go to the pictogram graph and have a wonderful interactive web site. At the bottom of the pictogram page, there is a farm animal pictograph link that would be good with a kindergarten or first grade.
