Hi Meg,
I was curious early on why simplifying fractions and radicals was absent from the curriculum as well. The answer I've received is the focus is on seeing equivalency which I believe simplifying is a sub set of that main skill. I would rather see it explicitly identified as a standard, but it answered my question about the exclusion.

Module 1 has an exercise that multiplies radicals w/ no instruction in the class notes, yet this is not a previous skill from grade 8.
