From [|Harding Math Specialist]
 * **7.EE.1-4** - **Expressions and Equations Short Tasks** - @http://www.map.mathshell.org/materials/tasks.php?taskid=399&subpage=novice - (Task) Students will look at several short tasks or warm-up type problems dealing with basic expressions and equations. These problems vary from expressions and equations using basic operation skills to those using evaluation and analysis.

 * My Humble Opinion **
 * 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
 * 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.
