linear Models & tables
IN THIS UNIT STUDENTS WILL BE EXPECTED TO:
Identify the rate of change and the initial value from tables, graphs, equations, or verbal descriptions.
with an initial value of 0.
Students gather their own data or graphs in contexts they understand. Students measure, collect data, graph data, and look for patterns, then generalize and symbolically represent the patterns. They draw graphs (qualitatively, based upon experience) representing real-life situations with which they are familiar.
Students take a function in symbolic form and create a problem situation in words to match the function. Given a graph, students create a scenario that would fit the graph. Students sort a set of "cards" to match graphs, tables, equations, and problem situations and explain their reasoning to each other.
Building on the study of statistics using univariate data in Grades 6 and 7, students are now ready to study bivariate data. Students will extend their descriptions and understanding of variation to the graphical displays of bivariate data.
Scatter plots are the most common form of displaying bivariate data in Grade 8. Students practice informally finding the line of best fit using a scatter plot. Students create and interpret scatter plots, focusing on outliers, positive or negative association, linearity or curvature. By changing the data slightly, students have a rich discussion about the effects of the change on the graph. Students use a graphing calculator to determine a linear regression and discuss how this relates to the graph. Students informally draw a line of best fit for a scatter plot and informally assess the fit of a function to their data.
