As with any site that contains rotating ads, be cautious as some could be inappropriate for your students. Repeatedly reloading the page (in advance) may help you feel more confident about what will appear for your students. The basic math practice generator (ArithmAttack) is a great tool that can be added to one’s own website (or also found at other sites). Teachers from upper elementary through high school can use this tool for transition times, quick practice, and class challenges. You can extend the practice here by having students track their scores graphically in their notebook.

Middle and high school math teachers will like the site’s algebra worksheet generator, which offers both print and online versions. Teachers choose the number of math problems from different categories (distributive, quadratic) and can even set the coefficients to be fractions. These could make for great practice resources for class warm-ups and homework reviews –- even in advanced classes.

Continue readingMath.com is an informational and instructional math site that provides some lessons and practice problems across several topics, as well as games and other resources (calculators, tables). Users' first impression will undoubtedly be influenced by the prominent ad space on the homepage. In fact, across the site, half (or more) of most pages is ad space. The ads are largely math-related, so distinguishing among links is difficult.

The “practice” tab is the main access point for math content, providing sequential lessons and practice sets in pre-algebra, algebra, geometry, and everyday math. While the text-based lessons are usable, most practice sets are non-operational, and unit tests don’t include answers. Other topics (calculus, for example) include links to related formulas, etc. The site also offers games and other resources –- including a “Wonders of Math” page with topics like tessellations and fractals. While there's a lot here, broken links abound.

First and foremost, teachers should know that Math.com's rotating ads could be inappropriate for schoolkids; these may or may not be blocked by a school's content filters. If you still choose to try the site, you'll find math lessons equivalent to a mediocre textbook –- not great, perhaps confusing, but not “wrong" per se. The practice problems are another story, though. Kids might get frustrated when the “Next Problem” doesn’t load, or when the site provides incorrect feedback (calling some correct answers "wrong").

Other features are better, though. The sudokus (under Games) are easy to use and include lots of levels, from easy to challenging. The tables, formulas, and glossaries are all functional references. The site’s calculators include interesting tools for prime numbers, circles, and percent. Be advised: Teachers will find many links in the teacher section outdated or invalid.
