Peer reviewedNevin, Mary Lou – Arithmetic Teacher, 1992
Proposes the use of literature to introduce new mathematical concepts. Presents a story to develop the concept of grouping, and follows with 11 activities related to the story in which students use dramatization and manipulative materials to develop new groupings, predict outcomes, validate their predictions, and discuss findings to develop the…
