New Activity & Assessment: Variables & Expressions

Every time I come up with a new lesson or idea I think of my students and how I can meet their needs. This lesson lets students work cooperatively with word problems and solve algebraic expressions. I love how easy these are to grade also. I don't include a rubric, but my card sort activities are always graded as 100% or try again until you get 100%! With that mentality the students love to try try again until they have figured it out.

Today I posted a new Common Core Lesson Plan on Teachers Pay Teachers titled "Variables & Expressions".

This lesson unit is intended to help you assess how well students are able to apply properties of operations as strategies to add, subtract, factor, and expand linear expressions, and understand that rewriting an expression in different forms in a problem context can shed light on the problem and how the quantities in it are related.
Included in this lesson are:
-one formative assessment (pre-test) task
-card sort activity with concept development of variables and expressions
-one extension activity for students to deepen their conception of expressions
-one summative assessment (post-test) task
-answer keys for all the assessments and activities

-how the lesson is tied to common core and mathematical practices
