E-activities can be used by teachers as a tool for documentation of electronic examples and practical problems with accompanying text, mathematical formulas, 2- and 3-D-graphics, geometric drawings, dynamic geometry-links as well as tables

For Students, the e-activities can function as an exercise book and can be used to examine problems and document their improvements in learning or solve problems with the help of notes created and inserted by themselves, saving all exercises within the file directory

Therefore, E-activities combine text lines, calculation lines, dynamic geometry-links and all applications like an exercise in a classic working booklet: describtive text, use of all applications by inserting so called "link-strips" and dynamic geometry-links as well as additional notes
