Building Proportional Reasoning Across Grades and Math Strands, K-8
Although the Common Core State Standards for Mathematics (CCSSM) and other mathematics curricula do not formally introduce proportional reasoning until grade 6, building fundamental ideas in the early grades helps students develop essential skills in ratios, percentages, and other proportional representations when they
reach the upper grades. The author includes examples and questions that help teachers see the larger purpose in teaching early concepts, such as unitizing, in ways that lay the groundwork for more complex ideas, such as ratios. Teachers and vertical teams can see how the concepts can build year by year, and the questions
are intended to be both interesting for students and useful in supplying teachers with diagnostic information. Chapters are organized by grade level around CCSSM.
Designed for use by teachers and coaches and in preservice instruction, the book provides the following:
