7.EE.1 requires students to add, subtract, factor, and expand linear expressions with rational coefficients. It makes sense to add, subtract, and expand with rational coefficients at this level. Is this also required with factoring? In other words, is a Grade 7 student expected to rewrite (-1/2)x + 3/2 as (-1/2)(x – 3)? If given these expressions, they should be able to determine equivalence for sure, but must they rewrite this on their own?
This was alluded to in the old blog on 6/21 (DavdSmith) and 6/24 (Ginger). Ginger mentioned New York’s interpretation of the standard, which is also vague.
Thanks
