There are two scatter plot activities included. First, students walk through and discover the steps to construct, interpret, and model scatter plots given an example with positive correlation. Then, students apply what they discover to gather and organize data, write an equation for a trend line, and draw conclusions about the relationship in a scenario with negative correlation.Students will be able to construct and interpret scatter plots, draw an appropriate trend line and write its…

This matching activity is a great way to have students practice finding unknown measures of interior and exterior angles of triangles. There are 12 problems students will solve and match up the answers to on the mat. Students need to apply the triangle sum theorem and also use supplementary and complementary angles to solve for the unknown measure. Teacher answer key included! Common Core Aligned: 8.G.5

FREE Students are asked to find an example of time-series data in which the dependent variable (y) varies linearly with time (X). The data should have a strong positive or negative correlation. Students will be asked to:Make a scatter plot of the data.Use a straight edge to draw a line of best fit.Find the equation of the line where they must show work for how they determined this.Use their equation to predict the value of the variable in 2012 and 2018.
