As a student, I never took the time to consider what measurement actually means. Chapter 14 discusses what measurement means and the implication it has on understanding measurement in math. TCSM defines measurement as "a number that indicates a comparison between an attribute of the object (or situation or event) being measured and the same attribute of a given unit of measure (341). By understanding measurement as a comparison method, students will begin to understand how an object can be measured using different units that describe the objects weight, volume/ capacity, length, or area. With the definition of measurement in mind, one way teachers can help their students gain conceptual knowledge of measurement is by helping them create models that demonstrate the idea of space and units that can be iterated to measure an attribute of an object. I like the idea of revisiting iteration and discussing how it is also used in measurement, which can ultimately reinforce fraction concep...
