Best Math Blogs and Sites

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 

Integral-calculator Integral calculator is a good site with a very powerful calculator for integrals.  I like the format of to enter the numbers.  The steps are a bit cumbersome but it is a great site for solving your integrals. This site is appropriate for: High school calculus students College calculus students Professionals

  Symbolab integral calculator Calculator for Integrals and other math problems.  This is definitely a good site to visit especially if you need a graphing calculator and you don't have one.  This site also shows problems worked. This site is appropriate for: Elementary students Secondary students College students Professionals

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.
