English Speaking Grade Schools in Freiburg

Hello,

My family may be relocating to Freiburg for Protected content for my husband's job. Because we will only be in Freiburg for a short time, and taking into consideration my son's personality, I would like him (6.5, currently in US Kindergarten) to go to an English speaking or German/English speaking school. I am having a hard time finding anything suitable via Google search.

Does anyone know of a English speaking international school or dual language German/English grade school in Freiburg? Alternatively, has anyone successfully obtained permission to homeschool their primary school aged children due to such a short stay in Germany?

I also have a 4.5 year old daughter that I would like to place in a preschool/kindergarten for a few days/hours a week. Is this possible and do you have any suggestions on a German/English speaking kindergarten?

Thank you very much for any insights you can provide on primary school options in Freiburg!
