The site is a useful source for math teachers as it provided examples and other related sources that would assist practitioners in developing instructional materials that would make teaching math fun and innovative. A comment on the site revealed that “students should not use virtual manipulatives blindly. Unless they are preceded by some kind of lesson or teacher introduction, students may not draw out the important mathematical ideas the manipulatives are intended to illustrate” (Donovan, 2008, 1). As such, the site is more useful for teachers and educators to enhance their skills prior to presentation in the classroom setting. Math Forum (2011). Math Forum Internet Mathematics Library. Retrieved from http://mathforum.org/library/topics/fractions/ The site created for Drexel University contains comprehensive information on diverse mathematical problems and applications explained by accessing indicated categories. This is an excellent website that includes exams, assignments, puzzles, webcasts, worksheets, and even software programs on demonstrations about math drills, among others. This is a very useful site for teachers due to the array of interesting and innovative information on mathematical issues and concerns which could guide, assist and enhance the learning of educators on the subject. The data, information and mathematical applications contained in the site are ready for immediate use by teachers and students in the classroom.
