By studying and practicing metacognition, teachers and parents are instilling positive attitudes toward learning by teaching how-to-learn skills that prepare children for assessing their own thinking about learning as they become more and more developmentally prepared. This book stresses the strategies for thinking in mathematical terms without paper and pencil. It contains a series of mentally manipulative card games for children age three to seven. Many games have been modified to allow teachers to use them in self-directed centers within classrooms. Sixty games and 10 activities are included. These games are aimed at improving number sense, arithmetic, comparison, counting, and other important skills for elementary mathematics students. (ASK)
