I like the Common Core State Standards for Math as they focus on objectives that students need to reach. However, some standards have way too many parts for them.
For instance, the standard CCSS.MATH.CONTENT.HSA.REI.D.11 is stated below. It would be ridiculous to teach this standard in an Algebra 1 class as students don't know logarithms yet. What do other teachers do in the way of teaching this standard for intersection of lines for Algebra 1? Is there such thing as reaching half a standard? What do others do?
Explain why the x-coordinates of the points where the graphs of the equations y = f(x) and y = g(x) intersect are the solutions of the equation f(x) = g(x); find the solutions approximately, e.g., using technology to graph the functions, make tables of values, or find successive approximations. Include cases where f(x) and/or g(x) are linear, polynomial, rational, absolute value, exponential, and logarithmic functions.
