"Mr. Robb's Math is a YouTube channel containing 555 videos produced by high school mathematics teacher Bradley Robb. Mr. Robb's videos explain and demonstrate solving problems in Algebra I, Algebra II, and Calculus. Most of the videos are recorded while Mr. Robb is teaching. You can find the videos on the Mr. Robb's Math YouTube channel or visit Mr. Robb's website WowMath to find the videos organized in sequence with accompanying screenshots."

Math videos - Algebra, Calculus, Algebra 2, graphing calculator, etc. Another great resource for math students. Add them to Khan Academy and you have quite a number of math screencasts.

Mathmaster.org is a free resource for your school where students can make use of the extensive video library (Khan Academy) and endless supply of printable math worksheets from any computer with access to the web. The video library covers K-12 math, science and other topics. Each video is approximately 10 minutes long and easy to follow. The website gives you the ability to easily customize each worksheet to target your student's specific needs

The next generation of the graphing calculator. Using a powerful and blazingly-fast math engine, the calculator can instantly plot any equation, from lines and parabolas up through derivatives and Fourier series. Data tables open up a world of curve-fitting and modeling. Sliders make it a breeze to demonstrate function transformations. As browser-based html5 technology, the graphing calculator works on any computer or tablet without requiring any downloads.

Check out the activities on this site, which give students immediate feedback. I looked at the math activities for Algebra/Geometry. Students can test their understanding of concepts quickly using this platform. Check it out!

Mission:   A free interactive math textbook on the web. Initially covering high-school geometry. I'm using it with 3rd graders for beginning geometry. I like the interactive aspects of it.

Great collection of math & science videos - especially for high school level. Each video has a transcript, which I though was helpful. This is a must have link on resources for students, and helpful for teachers as they look at presenting information.

Interactive video tutorials in math & science - FREE accounts for teachers. Teachers can use them as part of a lesson to engage students. 

High school math teacher, Brad Robb, has made available his course notes and instructional videos for AP Calculus (which he has posted on YouTube.

High school math teacher, Brad Robb, has made available his course notes and instructional videos for Algebra 2(which he has posted on YouTube.

High school math teacher, Brad Robb, has made available his course notes and instructional videos for Algebra 1(which he has posted on YouTube.

"During class time, the teacher will stand at the front of the room and hold forth on the day's topic. Then, as the period ends, he or she will give students a clutch of work to do at home. Lectures in the day, homework at night. It was ever thus and ever shall be. But one American teacher is taking a different approach - and in the process, he's offering a lesson in innovation for organizations of every kind. Karl Fisch is a 20-year veteran of Arapahoe High School, located south of Denver, Colorado. For the past 14 years, the one-time maths teacher has been the school's technology coordinator." Learn about the Fisch Flip - instead of having students do algebra problems at home after listening to the lecture at school, he has flipped it around, and puts his lectures on the web and then does the work with students at school. It's working well. Check out his videos here: http://www.youtube.com/user/karlfisch

Scholastic Study Jams is a fantastic collection of over 200 learning resource collections. Study Jams are videos, slide shows, and step by step explanations for science and math that will have your students discovering everything from invertebrates to the water cycle and the rule of divisibility. Each Jam includes a teaching video/step-by-step/slide show, key vocabulary, and a test yourself section where they can practice what they have just learned.

Mobile4Math has come out with Java-based apps for mobile phonesthat will graph functions (linear, quadratic, etc.), help students with the process of solving equations and inequalities, a qualitative graphing app, etc. The cool thing is that you can download the application for free or try them online using the Live Demo page.

"Math Time Attack! has Flashcards, Quiz and Test modes to help learn and recall multiplication, division, addition and subtraction with an emphasis on speed and accuracy."

Cool site with 830 papers you can download. Really great for math & music teachers, but there is stuff here for anyone.

Teaching Channel has some engaging videos covering a variety of topics that also support the Common Core.

A fairly new teacher has come up with a way to help her anxiety-ridden AP Calculus AB students relax more in class. She's using an approach dubbed by her students as the "backwards classroom." The practice can be used with or without computers or other smart devices, and the results have been remarkable: There's evidence that achievement is improving and that the teaching style suits motivated students well.

Wolfram|Alpha is a free online computational knowledge engine that generates answers to questions in real time by doing computations on its own vast internal knowledge base. Our long-term goal is to make all systematic knowledge immediately computable and accessible to everyone. This can be valuable to educators in many ways. * This allows you to: interact with your results using sliders and controls; rotate and zoom 3D graphics and visualizations, and manipulate results directly in your browser. * "Sometimes being able to change parameters dynamically just enriches what is already rather complete output. But often, it's what really makes the output meaningful." Wolfram|Alpha introduces a fundamentally new way to get knowledge and answers- not by searching the web, but by doing dynamic computations based on a vast collection of built-in data, algorithms, and methods.
