One-time German (Deutsch) tutoring for primary school student in Schlieren

Hello, I am looking for individual German (Deutsch) tutoring for a primary school student. I would like the tutoring to take place in Schlieren at the student’s home. This is planned as a one-time session. I have not set an exact number of hours yet, so I would appreciate your suggestion for a suitable lesson length. The focus can be on school topics in German and targeted practice where needed. It would be great to build confidence in the subject and make learning feel more manageable. If you are available for a one-off lesson in Schlieren, I would be happy to hear from you. Thank you.
