Yesterday I posted a new Common Core Lesson Plan on Teachers Pay Teachers titled "Linear Relationships with Scatter Plots". This lesson unit is intended to help you assess how well students are able to know that straight lines are widely used to model relationships between two quantitative variables. Also that scatter plots suggest a linear association, informally fit a straight line, and informally assess the model fit by judging the closeness of the data points to the line.
Emphasis is on the Common Core Benchmark 8.SP.A.2
Included in this lesson are:
-one formative assessment (pre-test) task
-card sort activity with
concept development of scatter plots and line of best fit
-one extension activity for students to deepen their
conception of scatter plots and line of best fit
-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
-19 Pages with answer keys included!!!
