• Wabbitemu creates a Texas Instruments graphing calculator right on your Android device. Wabbitemu supports the TI-73, TI-81, TI-82, TI-83, TI-83 Plus, TI-83 Plus Silver Edition, TI-84 Plus, TI-84 Plus Silver Edition, TI-85, and TI-86. Fast and convenient, Wabbitemu allows you to always have your trusty calculator with you. Because Wabbitemu is an emulator, the calculator it creates will act exactly like the real thing. 

  • First, we built our best-in-class HTML Desmos graphing calculator, which millions of students around the world use for free, including student who are blind or visually-impaired. Our partners have also embedded the calculator in digital curricula and on digital assessments so students spend less time worrying about technology and more time thinking about math.

    More recently, we've built hundreds of digital activities, covering grades 6-12 and expanding quickly to other areas of math. Those activities take advantage of everything that makes computers special. They invite students to create their own mathematical ideas, rather than just consuming ours. They encourage students to share their creations with each other, rather than with a grading algorithm. We distribute those activities for free on our website and through partnerships with curriculum publishers.

  • IXL helps students excel! With thousands of topics in math, language arts, science, social studies, and Spanish, there's always something new to explore. IXL sets a new standard for online learning, offering unlimited algorithmically generated questions, real-time analytical reports, and dynamic scoring to encourage mastery. Released in 2007, it has since become the world's most popular subscription-based learning site for pre-K to high school. With more than 7,000 unique and challenging skills to master, IXL offers a dynamic and enjoyable environment suitable for any learning style. Students who use IXL are succeeding like never before.

  • Khan Academy offers practice exercises, instructional videos, and a personalized learning dashboard that empower learners to study at their own pace in and outside of the classroom. We tackle math, science, computer programming, history, art history, economics, and more. Our math missions guide learners from kindergarten to calculus using state-of-the-art, adaptive technology that identifies strengths and learning gaps. We've also partnered with institutions like NASA, The Museum of Modern Art, The California Academy of Sciences, and MIT to offer specialized content.

  • Get More Math is designed by a math teacher to ensure that the answer is: yes!  This math practice program builds math practice sessions for each student that include both new material and thorough review of old concepts and skills.  As the year progresses, the teacher can gradually select more types of problems for these sessions.  Every day, a student logs in to a new mix of practice problems, selected for her based on data collected during all her former sessions.  Is she weak on graphing?  There will be a graphing problem.  Is she a champ at multiplying decimals?  Probably there won’t be any problems of that type presented, although occasionally GMM will include one during a mixed review session to make sure she still remembers.

    When a student gets a problem wrong, he must correct it and then complete an additional, similar problem before moving to a new problem type. Also, GMM notes the error and ensures that in following days this type of problem appears again.

    Using GMM, students complete more math problems with greater variety and higher accountability.  As a bonus, students love using GMM!  They appreciate the ability to earn game time and instant messaging, as well as the option of competing with other students.  They like to see colorful skill indicators as they gradually advance levels.


  • Practial Algebra Lessons: Purplemath's algebra lessons are informal in their tone, and are written with the struggling student in mind. Don't worry about overly-professorial or confusing language! These math lessons emphasize the practicalities rather than the technicalities, demonstrating dependably helpful techniques, warning of likely "trick" test questions, and pointing out common student mistakes.


    These free lessons are cross-referenced to help you find related material, and the "Search" box on every page is available to help you find whatever math content you're looking for.

    Before going to class, some students have found it helpful to print out Purplemath's math lesson for that day's topic. Purplemath's pages print out neatly and clearly. You can take notes in the margins or on the flip-side of each sheet. Then, after class, return here for the next topic. Let Purplemath help you always be prepared!
