The materials for project interactivate fall into three main categories, activities, discussions, and lessons. There are some additional support materials in the form of an overview of the goals of the project, a dictionary, standards for middle school mathematics, and hyperlinked tables of contents for several middle school math texts. The table below gives further information, and provides links to more detailed indices for the materials. These more detailed indices group the materials by the categories outlined in the NCTM Principles and Standards for School Mathematics and the NCEE Performance Standards for Middle School . An activity is an interactive, computer application designed to teach students about a concept through hands-on experimentation.
Activities usually present good opportunities for group work as well as individual investigation.
Support materials, which include handouts, tables, worksheets, etc., are available for many of these activities and can be accessed from the why page for that activity. A discussion is background material written in the form of a dialogue. Each discussion is devoted to one concept, or more rarely, several closely related concepts. Some discussions are based on activities, some are independent. Discussions lead learners to concepts, introduce vocabulary, and help to develop important formulas and structure.
