Dr. McCallum, thank you for your prompt response.
You mentioned a test case. The first example that comes up in a Google search is some work from the state of Oregon: http://www.mesd.k12.or.us/si/pdf/Prioritized_Mathematic_CCSS-1.pdf.
In their document I think they’ve used yellow highlighting to indicate the standards they feel are most essential; and when I examine the ones at the high school level in particular, my feeling is that there are several instances of non-marked items that represent deviations from what’s typically been in math courses. But, they are careful to point out that they aren’t suggesting eliminating any standards, rather just prioritizing them. I think my question to you was prompted by a concern that as soon as a prioritization like this is produced that only the yellow-marked items will end up being the curriculum in many classrooms.
