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.

Although this website doesn't appear especially engaging, there is a wealth of information and activities just waiting to be explored. The two main topics, Differentiation and Integration, both include numerous subtopics with a great deal of information. This website, created by the BBC, includes review information (referred to as "revise") and online tests created specifically for calculus students ages 16+. Some of the material would be useful in pre-calc.

The website includes a Site Guide (to assist teachers, parents, and students in navigating the site) and an "Ask a Teacher" link for students to read previous questions from students (and the answers) about specific difficult concepts. Since this site was created by the UK, you may notice some slight language differences. Much of the information is available in a printable format. A few of the activities require Flash. You can get it from the TeachersFirst Toolbox page..

Calculus on the Web provides Pre-calculus, Calculus, and Algebra problems for visitors to solve. Click on a math book to choose your course. Each book is divided into chapters and sections. View the entire index by clicking the "index" button. Click on the topic buttons to enter each section. Students do not need to log in to use the practice problems. Only students enrolled in a COW-registered class can log in to record their progress. Problems are color coded to show difficulty. Blue has a difficulty level of easy, purple is slightly more difficult, and red is difficult. A sample problem is given and then students are provided with additional problems to solve using traditional means with a calculator. Clicking "check your answer" will provide you a right or wrong response. There are unlimited tries if the answer is wrong. Hints for typing in formulas are given.

This site is older and does not use animation or graphics. Though the interface is older, students may find it easier to navigate. The problems are pretty straight forward, and they are not timed during problem-solving.

Use Math mistakes to uncover the most common math errors and perhaps learn a little more math as well. This site has "Real Mistakes from Real Student Work” and “Math Facts Students Should Know." Browse "Common Algebra Mistakes," "Common Trigonometry Mistakes," and "Common Calculus Mistakes" by using the drop down menus along the top or through the brightly colored buttons. Each area is also broken down into smaller subject areas such as "Pre-algebra" and "Radical Expressions" with several examples given for each. Each example provides the problem and the example mistake that is made. Rolling your mouse over the problem provides a clue to the error, while rolling over the correction area provides the right answer. There are also explanations of the errors and how to avoid them. Choosing the drop down on the example page allows the student to view as a plain web page or as a pdf file. Other links include "Algebra facts," "Trigonometry facts," and "Calculus facts" which contain flash cards and learning center activities. Note: Links to Amazon for math books of interest are listed, as well as a blog link and links to apparel for sale. Steer students clear of these areas. This site requires Adobe Acrobat.

TeachersFirst Edge entry: for moderately adventurous technology users. Create and collaborate on Excel spreadsheets using this online tool. You have choices to create and edit using the actual Excel program (with macros enabled) or edit in your browser--a more secure option for those concerned about macros. A user can create or upload an excel sheet and share it with others as a read only OR editable sheet. No more need to email versions around and have multiple users adding and changing versions that become impossible to "merge." The free membership seems just fine for schools. See a sample by logging in as "tf@tf.com" with password "test." You can even add to the TF sheet to play with the tools. Or click the "demo" log in to experiment with sheets created by other curious users like you.
