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.

Explain why the sum or product of rational numbers is rational; that the sum of a rational number and an irrational number is irrational; and that the product of a nonzero rational number and an irrational number is irrational. > > > > Interval Notation? > > Module 1 discusses the use of interval notation but none of the standards directly include it.
