phet Scientific Simulations This is a free site that has scientific simulations for learning math, physics, chemistry, and other science.  The simulations lets you see in a lab format so you can learn principles by observing. Most of these are animated games which may show something like a water filling up a tank or trajectories.  Regarding math there are the following principles: Curve fitting Graphing Area Balancing Fractions Linear regression This is a good way to learn math and is very helpful to show students what is happening as opposed to just seeing formulas. This is appropriate for: Grade school students Middle and junior high students High school students College students 

My Math Forum Post your question and get an answer or if you are like me you can go to the site to answer questions.  This is a pretty decent site to correspond with others on how to solve problems.  This forum has a lot of posts and appears to have a lot of teachers as well as professors.   This is a great site to get your problem solved.    The forum covers these subjects: Arithmetic Algebra Abstract Algebra Geometry Precalculus Trigonometry Real analysis Topology Probability and statistics Linear algebra Calculus This is appropriate for: Math 3 through 6th grade students Middle and Junior high school students High School students College students Professionals Life long learners

Math 10 Math Forum Post your question and get an answer or if you are like me you can go to the site to answer questions.  This is a pretty decent site to correspond with others on how to solve problems.  Besides forums, this site has practice tests and also has problems and solutions.  I did notice that some of the problems go a long time without being solved but there are a large variety of problems and this is a worthy site.  The forum covers these subjects: Algebra Geometry Precalculus Trigonometry Probability and statistics Linear Algebra Calculus Differential equations Physics Computer algorithms This is appropriate for: Math 3 through 6th grade students Middle and Junior high school students High School students College students Professionals Life long learners

Wolfram Alpha This is one of my favorite sites.   I often refer my students to this service.  This site  has both a free and paid services. The free service is adequate for most calculations.  When you enter a function: It will give a graph of the function.   For instance lets say you enter xsinx and it will graph the function.  This will give you a graph for just about any function that you enter.  This is a graphing calculator. The calculator will give you the domain and range of the function. This will give you a series representation of the function. This will give you an improper integral of most functions if the derivative exists. This will give you a derivative of most functions if the derivative exists. This will find the maxima and minima of the function. This will give you and alternate function. This site is recommended for: Arithmetic Pre-algebra Algebra 1 Algebra 2 Pre-Calculus Calculus Linear algebra Students...
