Introduction to Representation, Gr. PreK-2

In Introduction to Representation, Bonnie Ennis and Kimberly Witeck share ways to help students use algorithms, graphs, manipulatives, diagrams, and other written and pictorial forms to express mathematical ideas. They offer an array of entry points for understanding, planning, and teaching, including strategies that help students internalize manipulatives and other models of their thinking so that they can begin documenting their mathematical processes.
