2
1. Standards2. Strategies3. Technologies
3
8.F.4 (Construct a function to model a linear relationship between two quantities.)Q & Acomputer
4
8.F.5 (Describe qualitatively the functional relationship between two quantities by analyzing a graph.)Video about bungee jumpingexcel spreadsheet
5
8.SP.1 (Construct and interpret scatter plots for bivariate measurement data.)Experimentsmart board (for group presentations)
6
8.SP.2 (For scatter plots informally fit a straight line and informally assess the model fit by judging the closeness of the data points to the line.) Collect data and make predictionsdocument camera (to show groups' transformation of the graph from the excel document to graph paper)
7
8.SP.3 (Use the equation of a linear model to solve problems in the context of bivariate measurement data, interpreting the slope and intercept.)Group work
8
8.SP.4 (Understand that patterns of association can also be seen in bivariate categorical data.)Demonstration on how to create double loop and slip knot
9
8.F.1 (Understand that a function is a rule that assigns to each input exactly one output.) If this standard is not described or reviewed before beginning the lesson some students might fall behind or not comprehend the activity.Small lecture
10
8.F.3 (Interpret the equation y = mx + b as defining a linear function, whose graph is a straight line.) Teachers should review this standard prior to the lesson as well so students are well aware as to what the slope and y-intercept represent and what the graph of a linear function looks like.Teacher-Centered: Q &A, demonstration, small lecture
11
Student-Centered: Q & A, video, experiment, collect data and make predictions, group work
12
have students present their group work; show the class their excel document and explain how they interpreted the graph
13
the teacher should ask the groups additional questions while they are presenting to assess their understanding of the lesson
14
give another set of data (already completed) and have them create a scatterplot themselves on graph paper
