Standards, Standards, Everywhere

The category I was assigned to focus on was Measurements, and right from the start one major difference is that the Common Core doesn't break down the study of measurements like the NCTM or CMP do. For example the NCTM really lays out a long term plan spanning K-12 whereby a student should come to fully understand the nature of what it means to measure things. This student would have a broad concept of the difference of standards with regards to units, be able to select the correct tool for what is being measured, and be able to covert within a given system as well as between two or more systems. In contrast while the Common Core does mention measurements as a standard and does lay out standards that are in line with the NCTM, it does not provide such a detailed framework for achieving this. The CMP only mentions measurements in relation to surface area, volume and angle measurements, and there is no mention of helping students build a philosophy and thus a deeper understanding of how measurement may be applied.
