Building numeracy in all students is a critical aspect of contemporary schooling. Building Numeracy has been written to assist all teachers, at all levels, to develop expertise and confidence in diagnosing student difficulties. This book helps teachers to understand how mathematical concepts and processes are constructed and connected; overcome mathematical misconceptions and inappropriate ways of thinking; plan and implement appropriate intervention programs to build students’ competence and confidence. A series of numeracy screening tests are provided to allow teachers to readily assess a class, small group or individuals. The tests provide a picture of strengths and weaknesses or gaps in understanding. Included is a CD-ROM containing a variety of digital resources designed to support the diagnosis and intervention processes. It also includes a series of instructional videos that demonstrate the effective teaching of key concepts and strategies.
