Mousemath from Eugenia Katz Kashirskaya

Mousemath is a playful math program for preschoolers that uses games to develop arithmetic skills, spatial thinking, and fine motor skills. The network of Mousemath clubs began in 2015, with the first classes led by educators Zhenya Katz, Anya Ryazanova, and Nata Malinovskaya, who were later joined by Dina Shur, Lena Tishina, and Sasha Pyatenko. Currently, the network includes over 20 teachers, with classes held at 30 locations across Moscow. Each session lasts 45-50 minutes and is held once a week, in small groups of 6-8 children per teacher or 8-12 children per teacher with an assistant. Classes are offered both in person and online.
