Both CPM and Desmos created eTools are located in the student and teacher eBooks within the lesson. Students without an eBook may find these eTools by course in the CPM Student Tutorials.
CPM eTools are designed to be exploratory.
Students can add their own text to most CPM eTools as well as manipulate objects about the display area. Students can save their work. This process provides the student with a link. At this point, the students need to store all saved links in a document or spreadsheet in order to retrieve the files.
