Skills
1. Add linear expressions with rational coefficients
2. Subtract linear expressions with rational coefficients
3. Factor linear expressions with rational coefficients
4. Expand linear expressions with rational coefficients
New Content
1. Factor linear expressions - I don't think this was in the 7th grade 2003/2009 ACOS, although it is in most 7th grade texts.
2. Expand linear expressions - I was not familiar with this term, but after researching it, I believe it means to simplify using the distributive property. This is again new to 7th grade ACOS but in most textbooks.
