Each of the six books in the "Thinking by Numbers" series provides clear and practical teaching strategies to help develop children's thinking skills through mathematics. The series focuses on the five main thinking skills outlined by the National Curriculum - information processing skills, reasoning skills, enquiry skills, creative thinking skills, evaluation skills - in addition to supporting development of memory/perception skills and metacognition. "Thinking by Numbers" offers a wealth of ideas for inspiring lessons and activities, supported by photocopiable problems through which children can apply the skills learned. Each book includes guidance on turning any lesson into a thinking lesson, how to apply thinking skills and teaching strategies across the curriculum, and advice on formative assessment.
