Hotmath.com provides online homework assistance for math students in the middle grades through college. Step-by-step solutions are provided for odd-numbered homework problems from over 150 math textbooks. While a complete listing of textbooks is not provided, prospective users can verify the inclusion of specific titles through a free trial membership. Topical coverage includes Pre-Algebra, Algebra I and II, College Algebra, Trigonometry, Geometry, Pre-Calculus and Calculus. A science section is currently in development. Users navigate to their textbook problems through subject browsing (e.g., Algebra). Students select problems, receive hints for completing formula steps and arrive at problem solutions. Relevant concept reviews are linked from each problem. Site design and navigation is spare and straightforward. Advertising for companies such as Texas Instruments and Smarthinking.com (a live online tutoring service) is displayed in the margins of several pages.
A "More Resources" section contains movie tutorials for Texas Instruments graphing calculators, review lessons, workbook activities and answers, and math activities and games. Some of these areas are still in development and need additional content. Hotmath.com is an emerging tutorial resource best considered on a case-by-case basis depending on student and district needs. Its provision of online content linked to classroom textbooks is worth further examination as a model for expanded student support and services. Ernie Cox, Libn., St. Timothy's School, Raleigh, NC
