This site offers many opportunities for math exploration for both teachers and students. Although they have a store and ads on the site, much of the site is free and worth a visit. One especially helpful portion of the site is the link to different types of calculators from basic to graphing to mortgage and loan calculators. Students and parents will find the homework section of the site helpful as it is categorized by different topics, then each topic is further divided into sections. For example, under fractions you will find definitions, reducing, adding and subtracting, multiplying and dividing. In each of those portions there is a section with a first glance (overview), in-depth, examples, and workout. There is also a unit quiz for each section. Another helpful area of the site is the practice section which offers practice in many different math skills such as square root, percent, and integers. The games section offers practice with critical thinking skills through logic puzzles and games such as chess.
