This set of materials is composed of 29 narrative cases written by teachers in grades 4-8 who participated in the Far West Laboratory's Institute for Case Development. The casebook is accompanied by a Facilitator's Discussion Guide that provides teaching notes for each case. The cases are centered in the domain of rational numbers and each is linked to a particular set of issues (e.g., building concepts, relationships, classroom discourse, manipulatives, invented algorithms, proportional reasoning).
