Using differentiated instruction in the classroom can be a challenge, especially when teaching mathematics. This book cuts through the difficulties with two powerful and universal strategies that teachers can use across all math content: Open Questions and Parallel Tasks. Specific strategies and examples for grades Kindergarten - 8 are organized around the National Council of Teachers of Mathematics' (NCTM's) content strands: Number and Operations, Geometry, Measurement, Algebra, and Data Analysis and Probability. This resource will help teachers create a more inclusive classroom with mathematical talk that engages students from all levels. Contents include: (1) Why and How to Differentiate Math Instruction; (2) Number and Operations; (3) Geometry; (4) Measurement; (5) Algebra; and (6) Data Analysis and Probability. Worksheet for Open Questions and Parallel Tasks is appended. A glossary, bibliography, an index of subject and cited authors, and an index of "big ideas" are also included.
