PRODUCT DESCRIPTION

This is a simple step-by-step list for student interactive notebooks.

Steps walk students through entering data, graphing the scatterplot and linear regression (tend line) in the Ti-83/84 family of graphing calculators. Screen shots of what the students see on their Ti are also included to encourage autonomy after initial instruction.

It is ready to be copied as a double-sided page and cut in half (long-wise), saving you precious paper! I hope you find this resource helpful!


TEKS

8.11(A) construct a scatterplot and describe the observed data to address questions of association such as linear, non-linear,
and no association between bivariate data

8.5(D) use a trend line that approximates the linear relationship
between bivariate sets of data to make predictions


Common Core State Standards

CCSS.MATH.CONTENT.8.SP.A.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.

CCSS.MATH.CONTENT.8.SP.A.2 - Know that straight lines are widely used to model relationships between two quantitative variables. For scatter plots that 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.
