MouseMatics: Unusual Math For 7-8 year olds

Jane Kats (Женя Кац) studied linguistics in the Russian State University for the Humanities in Moscow, and is active as a blogger and an organiser of various educational and recreational activities for children. She creatively interprets a lot of literature on early mathematical education, which had a thorough tradition in the (former) Soviet Union. This book helps to bring this legacy to every day practice. It's a great thing that her books are eventually available beyond Russia via Amazon (at least in Germany). The quality of paper and illustrations is very good too. The book is originally published by Moscow centre for continuous mathematical education.

I expected it to be an English book as the title suggests, but it's Russian. Other than that, I don't think it's a bad book.
