Topics/Standards:
8.F.1 Understand that a function is a rule that assigns to each input exactly one output. The graph of a function is the set of ordered pairs consisting of an input and the corresponding output.
8.F.2 Compare properties of two functions each represented in a different way (algebraically, graphically, numerically in tables, or by verbal descriptions). For example, given a linear function represented by a table of values and a linear function represented by an algebraic expression, determine which function has the greater rate of change.
Investigate patterns of association in bivariate data.
8.SP.1 Construct and interpret scatter plots for bivariate measurement data to investigate patterns of association between two quantities. Describe patterns such as clustering, outliers, positive or negative association, linear association, and nonlinear association.

SCATTERPLOT/LINEAR CORRELATION ACTIVITY
Students build bridges with pieces of paper and determine the correlation, if any, between the number of layers of paper they use and the strength of their bridge.
SCATTERPLOT/GOLDEN RATIO ACTIVITY
CELL PHONE DATA PLAN ACTIVITY
REAL WORLD CONNECTIONS!
Analyze functions in multiple representations and use the concepts of "rate of change" and intercept to determine which data plan is best under certain conditions. Task includes worksheet and follow up discussion questions.
Patterning Activity (NEW)
This activity can be used as a "higher order" task. It can be used as a group activity. Students develop methods for finding the equation of a function given a geometric pattern, using a table and/or graph of ordered pairs.
