National Library of Virtual Manipulatives

The National Library of Virtual Manipulatives (NLVM) is an NSF supported project that began in 1999 to develop a library of uniquely interactive, web-based virtual manipulatives or concept tutorials, mostly in the form of Java applets, for mathematics instruction (K-12 emphasis). The project includes dissemination and extensive internal and external evaluation.

The NLVM is a resource from which teachers may freely draw to enrich their mathematics classrooms. The materials are also of importance for the mathematical training of both in-service and pre-service teachers. The library is actively being extended and refined through projects including the eNLVM, a project to develop interactive online learning units for mathematics.

AdaptedMind was created by graduates of Stanford, Berkeley and Harvard to improve the way children learn. We aspire to bring a revolution to education, improving it by pushing the frontier in learning science.

Your child is unique. But the math books and exercises your child does are the same as other children’s. AdaptedMind creates a custom learning experience for your child. A learning experience that identifies your child’s strengths and weaknesses, and delivers a curriculum and exercises that adapts to these needs. That’s adaptive learning.

We created our curriculum in consultation with teachers, parents, and most importantly – children.

The result is a learning experience that significantly improves performance, guaranteed.


StudyStack.com strives to help people learn what they want to learn. The StudyStackTM concept was designed to help people memorize information about various subjects. Using the StudyStack web site, you use your computer to display a stack of “virtual cards” which contain information about a certain subject. Just like flashcards, you can review the information at your own pace discarding the cards you’ve learned and keeping the ones you still need to review. When you enter data on study stack, the data can be studied using many different activities such as flashcards, a matching game, a word search puzzle, and a hangman game. You can also export the data to your cellphone or PDA so you can review it when you are away from the computer.


Alan Walker (owner and CEO of multiplication.com) has been an educator for over 30 years. He is currently the Technology and Data Systems Director for a school district in Washington State.

The book, Memorize in Minutes: The Times Tables, was based on a method Alan developed in his classroom over 10 years ago. Using pictures and stories, he was able to teach ALL of his students the times tables in a few weeks spending just 10 to 15 minutes a day. He shared his method with other teachers, and these teachers provided constructive feedback in return. The final book was a result of hundreds of hours of research and development. His newest book, Multiplication in a Flash, uses “quick tricks” (mnemonic devices) to teach the twos, fives, and nines, and uses pictures, stories, and activities to teach the remaining facts.

Alan’s honors include Washington State Teacher of the Year Nominee, Washington State Christa McAuliffe Award for Excellence in Education, and Washington State Technology Leader of the Year.

In February, 1997, Susan Brooks and Bill Byles began a collaborative effort to extend assistance to fellow teachers. In November of 2000 that project expanded to a web presence known as Internet 4 Classrooms (“i4c”), a free web portal designed to assist anyone who wants to find high-quality, free Internet resources to use in classroom instruction, developing project ideas, reinforcing specific subject matter areas both in the class and at home and even for online technology tutorials. The portal is used by teachers, parents and students of all ages on six of the seven continents (there are not many classrooms in Antarctica) and is available to anyone with an Internet connection. We do not charge a subscription fee. To find out more about Susan and Bill, please go to our short bios.

XtraMath is a Seattle-based 501(c)(3) nonprofit organization dedicated to math achievement for all. Our goal is to develop effective, efficient, adaptive and intrinsically rewarding supplemental math activities and make them available for free.

XtraMath started in the fall of 2007 when David Jeschke, a computer programmer, volunteered at a local elementary school and recognized the need for an individualized math practice program. XtraMath spread rapidly to other classrooms by word of mouth and the program continues to evolve to meet the needs of the students, teachers, and parents.

The teacher who appears in the student activities is Christopher Robert, a National Board Certified Teacher in the Seattle School District. In 2009 Chris was honored as a “Hero in the Classroom.”

The teacher who appears in the introductory videos is Denise Ohlson, a National Board Certified Teacher in the Peninsula School District. She has taught for many years in all the elementary grades. In addition to being a teacher Denise is also a voice artist.

Erika Newell answers email questions from parents and teachers. She has a BA in Mathematics from DePauw University and likes helping people use technology to its full potential. Her children love using XtraMath.
