Originating in Russia, mathematical circles are a teaching method designed to teach logical, analytical, reasoning, and mathematical abilities. Here, the technique is adapted for US students who have less preparation in math and less motivation. Author Burago, a software developer and parent who started mathematical circles in the Seattle area, presents 29 weekly lessons, complete with lectures and discussion questions, problems and solutions, games, activities, and contests, along with tips on running the group. The book can be used as a full curriculum or as a collection of activities. Annotation ©2013 Book News, Inc., Portland, OR (booknews.com)
