Young Mathematicians at Work: Constructing Number Sense, Addition, and Subtraction

Young Mathematicians at Work by Cathy Fosnot provides a new look at the teaching of computation. It moves beyond the current debate about algorithms to argue for deep number sense and the development of a repertoire of strategies based on landmark numbers and operations. Sample minilessons on the use of the open number line model are provided to show you how to support the development of efficient computation.
