Minimath has been conducting courses for early mathematical education in kindergartens in Vienna and Lower Austria (as well as at other educational institutions such as the VHS or the ZOOM Children’s Museum) since 1998. Through his publishing house von Oemis, Simeonov also distributes workbooks for early mathematical education and a portfolio for teaching mathematics at educational institutions for elementary education.
