Designed for intermediate grades, the activities for the TI-10 and the TI-15 Explorer use the calculator as a data-generating device to support exploration of mathematical ideas. Each activity consists of Teacher Pages that give directions for the activity, and a student Recording Sheet that provides a method for organizing collected data.

The Teacher Pages for each activity contain: the content strand, overview of the purpose of the activity, mathematical concepts addressed, introduction section, collecting and organizing data for the problem, analyzing data and drawing conclusions, and continuing the investigation with ideas for related problems and activities. The student Recording Sheet for each activity is designed to provide an organized-yet-open-ended structure in which students can successfully record and analyze the data that they collect in the activity. The activity book is available for purchase or can be downloaded freely in PDF format.
