Khan Academy hosts a range of math courses, including courses covering elementary school content up to courses covering linear algebra and other advanced subjects. Another resource is Visual Calculus, which provides tips for using popular graphing calculators.
Khan Academy has lessons that provide video tutorials. The lessons are relatively short, covering single topics that might encompass only a portion of a full class. Khan Academy also provides a popular online community that allows learners to ask questions. Users can also access a number of tools tailored to specific courses and a dashboard that helps students and their parents track progress.
Visual Calculus covers topics ranging from precalculus to advanced calculus topics. The lessons also show students how to use Texas Instruments graphing calculators, which students can use on many standardized tests. Learners can also access Web-based interactive tools, including quizzes.
Those looking for fun ways to practice a number of subjects can check out Math Playground, which contains a number of games. Some of these tools simulate real-world games that require mathematical knowledge, such as "Mancala." Others cover more academic subjects, such as interpreting graphs. The games "Identify Coordinates" and "Locate Coordinates," for example, can help algebra students learn some basic elements of plotting and reading a graph.
