## Cooperation with lehrer-online.de - Page 2-

Over a period of more than seven years, numerous teaching examples were developed in cooperation with Dr. Diesel from lehrer-online, which demonstrate in a special way the possibilities of interactive dynamic worksheets for teaching practice.

Lesson sequences were developed for the following topics. All examples presented are based on my own mathematics lessons and have been used by me several times in class.

The corresponding teaching unit with all freely usable materials can be found on lehrer-online.de.
