There are plenty of helpful sites to learn content. What makes this so special? Created by an uncle wanting to help his nieces learn material, Khan Academy has grown into a Creative Commons attributed site for helping all students. What information is available? Maybe one should ask: What are you looking for? View a vast array of videos on many topics: SAT prep, Algebra, Geometry, Chemistry, Biology, History, Trigonometry, Calculus, Economics, Brain Teasers, Banking and Money, Statistics, Finance, Physics, and more....Whew! The only problem? The videos are hosted on You Tube. If your district blocks You Tube, then they may not be viewable. You could always view that at home and bring them to class “on a stick” to share. Use a tool such as Vixy reviewed hereto download the videos from YouTube.

This site features engaging movie scenes (in Quicktime and Flash formats) that involve Math problems. Beside each clip and title is an explanation of the Math concept in the clip. Most are secondary level, but a few are for lower grades. If you click on the TITLE of the movie, you will be lead to a site to purchase, rate, and/or view the movie in its entirety. To avoid this confusion, be sure to click on the “Play the Flash Version or QuickTime” links. These links lead directly to the “math clip.” Links at the bottom lead to other movie collections websites. This site requires Flash or Quicktime. Get either here

Choose from a wide variety of lesson plans and ideas for elementary, middle school, high school, or college, all created using GeoGebra. View concepts on individual pages that house interactive applets (mini-programs) and downloadable, zipped versions. Depending on your computer's security settings, you may need to "tell" your computer to "trust" the source of the activity before it will "Run." Explore Math resources for Art, Music, and Physics. Some of the available activities have demos with audio explanations, as well. Be aware this wiki allows users to add content. You must log-in to add content, but you still may want to preview for accuracy before you share this site with your students. The users appear to all be math teachers, but some activities may be created by students.

This site, designed especially for middle school students, highlights the basic foundations of math, geology, chemistry, physics, and biology. Although this site is recommended for middle school students, it is also appropriate for high school students studying the subject areas. It is mainly a "text" site, without interactives. However, this is a great resource for explaining complex topics, researching specific topics in science and math, and much more. Each general area (i.e. geology or biology), includes several sub-topics. There are also links to activities for students, project ideas, and Teacher's Guides. There are two caveats: there are some advertisements -- nothing too distracting -- AND some of the suggested activities include "buying" a book from Amazon. You do NOT need to purchase anything to take advantage of this free resource!

This site offers FREE interactive math tools: qualitative grapher, piecewise linear grapher, linear transformer, function analyzer, quadratic transformer, system solver, plopit, and proportioner. Originally the interactives required special software, but they now run directly from the web site without any special installation or download. The interactives all include a real-time connection between math concepts (graphical or symbolic) and the representations. The activities provide visual illustrations to enhance algebra class. They allow for accelerated learning. And you are even able to save images to share with classmates.

The "Qualitative Grapher" demonstrates the meaning of a function and see how it can be seen as something changing over time. The "Proportioner" highlights scale and proportion and allows you to compare image dimensions. All of the other individual activities highlight other upper level math skills. This site requires Java and Adobe Acrobat. You can get both from the TeachersFirst Toolbox page.

This online calculator is able to graph in two or three dimensions. The advantage is the ability for all students to have the fastest, most capable calculator in class. Calc5 can be used to graph sin graphs, logarithms, and likely any graph needed in High School Math classes. A graph can include multiple functions. In order to see them, simply drag the graph. It is easy to zoom in and out of the graph. Students can take a screenshot of the graph in order to show in assignments or an online space. In Mac, simply hold the apple, shift, and number 4 key at the same time. Use the cursor (now a cross-hair) to drag a box around the picture and let go. The picture will be saved to the desktop. For PC, use the "Print Screen" button, then PASTE into any document or PowerPoint.
