Clothesline Math: The Master Number Sense Maker lays the theoretical groundwork for intentionally teaching number sense at all grade levels. Written by Chris Shore, this essential resource empowers math teachers with detailed instructions on implementing Clothesline Math in both elementary and secondary classrooms. It includes tips and strategies for facilitating the mathematical discourse that naturally ensues among students when Clothesline Math is implemented in the classroom. This strategy book includes everything that teachers need to prepare, implement, and assess Clothesline Math lessons. At the elementary level, the lessons cover essential math concepts such as whole numbers, place value, fractions, order of operations, algebraic reasoning, variables, expressions, and one-step and two-step equations. At the secondary level, concepts include exponents, roots, integers, absolute value, variables, multi-step equations, inequalities, slope, geometry, algebra, functions, statistics, trigonometry, and pre-calculus. Differentiate instruction by implementing Clothesline Math, a strategy that inherently supports the needs of diverse learners. Aligned to state and national standards, this helpful book will get students excited about math as they engage in meaningful mathematical discourse and learn to think and speak like mathematicians.
