New Product: Direct Variation Activity

Last week I posted a new Common Core Lesson Plan on Teachers Pay Teachers titled "Direct Variation". Why did I create this? A GREAT QUESTION...I created this activity to help my students remember the different between direct and inverse variation. Without fail every year my 7th grade students would say, "I did okay on the test, but I couldn't remember the difference between direct and inverse variation". That is why I created this lesson activity and "Inverse Variation" activity. These activities help the students develop concepts on their own so that they retain the information about what makes a direct variation equation versus an inverse variation equation.

This lesson unit is intended to help you assess how well students are able to model linear relationships between two quantities, graph proportional relationships, recognize and represent proportional relationships, identify the constant of proportionality, and represent the proportional relationship with an equation.

Included in this lesson are:

-one formative assessment (pre-test) task

-card sort activity with concept development of direct variation

-one extension activity for students to deepen their conception of direct variation

-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
