Booklets on Mathematical Culture edited by Li Tatsien serve as out-of-class reading material in mathematics and mathematical culture for young students. Each booklet involves a mathematical theme, with more attention paid to the cultural value hidden in the mathematical knowledge. Since 2007, more than 20 booklets have been published, and the first 20 are collected as Series I and Series II. Besides an overall introduction to the two series, the author categorizes the 20 booklets and furthermore, he selects 10 out of the 20 and make meticulous review on their mathematical contents and cultural values. The author’s views on mathematics, mathematical culture and mathematics education are also reflected in the introduction and reviews.
