he YAY MATH video project is a free service dedicated to meeting the growing need for math success in a POSITIVE, LIVELY, and CONFIDENCE BOOSTING way. YAY MATH stands as the only online video lesson series filmed in a live classroom, with real student interaction. Since its inception two years ago, and over a million YouTube views since, gone are the days of the "I just can't do math" style of thinking. It's time to evolve. It's time to re-invent our entire approach to success.

Get the Math is a multimedia project about algebra in the real world. See how professionals working in fashion, videogame design, and music production use algebraic thinking. Then take on interactive challenges related to those careers.

OK, this is a pretty cool game site that is all about teaching and learning. I played the multiplication game longer than I should have and even played with the pet hamster for a while. He runs on that whell a long time. From the website, "All games here were made by Exuberant Games. Each game goes through important information for a certain subject matter for grades Kindergarten through 6th grade. The math games are great if you need to review your math facts for addition, subtraction , or division. Be sure to check out our new games for other subjects.

MIT Open Courseware. A great way for students to access material that may not be presented at their level anywhere else. For that matter a great place for teachers to brush up and expand their thinking. I spent about an hour on the combinatorics course developed by an MIT student for high school math students who are 'bored' by high school math classes. If you are interested, it pushed my understanding pretty quickly!

The Middle School Portal 2: Math and Science Pathways project (MSP2) is a component of the National Science Digital Library (NSDL) that supports middle school educators and youth by offering contextualized, high-quality resources and promotes interactivity, collaboration, and knowledge-sharing among its users.

Killing two birds with one stone. Here are some interesting facts about social networking and use among 35-54 yo age group growing by 60% recently according to Forrester. Also, if you are looking for a read-aloud to do with math students, here's a great example to use with them. The topic is social media, the content is proportional reasoning, data analysis, and interpreting real-world data. For example if usage among 35-54 yos has grown by 60% what does that mean among the sample of 4500, what does that mean among the sample of the US population, if previous usage was 15% of that age group, what percentage of that age group now use it? Etc. Good math/science reading is as close as your local USA Today/Yahoo homepage/iGoogle/news RSS

Nice set of applets that let students explore fraction understanding from multiple perspectives and models. I love that they use a variety of models for fractional development, including bars (multiple versions), sets, and linear. From the site:  "Why Fractions? Fractions are one of the earliest stumbling blocks for students in math. Our goal is building conceptual understanding in fractions as a basis for comprehension in all later topics."

Math videos to help explain skills/concepts. Tends to be very skill based, but offers multiple takes on the same skill so if a students doesn't get it from one person the next might be a better fit, short videos makes it plausible that a student might use, GREAT integration of vocabulary. Well worth incorporating into classroom practice to help students understand how to use formulas or manipulate equations. Also they are GREAT models if you want kids to create their own.

Interesting approach to using flip in a mathematics classroom. I love having students create product rather than just solving problems. I would even like to see students create their own problems in the future. 

Another educational use for twitter. Create a poll, tweet your question, gather your data, explore the data. Could be a social studies tool, a psychology tool, an English tool, a math tool, or science tool. I guess if you analyze the data you receive all the questions would be a math tool.

A video that uses production of the car, Mini, in Britain to reinforce math concepts like, ratio (lots of examples but one car every two minutes, or one in four cars are convertables), shapes used in production. Can be split into small segments.

Drill and practice quizzes for grades 1-6 math.

Podcasts for simple shortcuts/tips for doing some simple math calculations. Mostly procedural but worth letting students listen to and use to develop their own.

Math instructional videos. Most are procedurally oriented, but the site has some promising aspects. There are a lot of resources and it does look fun. 

Great new number sense math app. Cost $0.99 at this time but uses: the capabilities of the iPhone well (motion, graphics), multiple representations including linear and circle models, decimals, fractions, percents. Is fast moving and progresses beyond 0 to 1 to have students estimating values like 0.26 on a number line from 0 to 2.  

Some great applets for use with math classes. From basic arithmetic modeling to modeling of integrals. From the University of Virginia these flash based apps will work on almost any platform except the iPod system (currently).

A collection of 279 Math Applets designed by International Education Software. Apps show individual concepts from multiple perspectives, usually conceptually from a diagram and graphically. Not very dynamic in that students wouldn't be able to manipulate multiple variables, but great to use with an interactive white board to show connections between representations and to confirm calculations/predictions.

Here is a phenomenal lesson, accessible to any child who knows how to subtract, and compelling to everyone, up to and including professional mathematicians. Get a kid engaged in it, and they'll do hundreds of subtraction problems without complaint, because it's helping them solve an honest mathematical mystery. I've seen this idea discussed in math education circles, but I haven't found any references to it online, so I want to share it here.

very interesting music creator. i'm not sure of it's value as a teaching tool (I don't know enough about music), but it is very cool, and there is a lot of math behind it.
