1 What's Your Rate of Change? Resource Type: Instructional Resource -- Promising Practice Discipline: Mathematics Ohio Standards Alignment: Grades 8–10 Professional Commentary: Students use regression methods available through technology to select the most appropriate model to describe collected motion data and use the model to interpret information. An activity sheet, discussion questions, step-by-step illustrations, and suggestions for assessment are included.... Resource Type: Instructional Resource -- Promising Practice Discipline: Mathematics Ohio Standards Alignment: Grades 7–10 Professional Commentary: This lesson is most meaningful to students in states like Ohio, where turnpike tolls are proportional to distance. Students use a toll ticket or a state website like The Ohio Turnpike to collect data on distance traveled versus the toll collected, and they create a scatterplot using spreadsheet software or a graphing calculator.... Resource Type: Instructional Resource -- Best Practice Discipline: Mathematics Ohio Standards Alignment: Grades 8–10 Professional Commentary: The consideration of cord length is very important in a bungee jump—too short, and the jumper does not get much of a thrill; too long, and ouch! In this lesson, students model a bungee jump using a Barbie® doll and rubber bands. The distance to which the doll will fall is directly proportional to the number of rubber bands, so this context is used to examine linear functions. An activity packet, spreadsheet applet, discussion questions, suggestions for assessment, extensions of the lesson, and prompts for teacher reflection are included.... 4 Glued to the Tube or Hooked to the Books? Resource Type: Instructional Resource -- Promising Practice Discipline: Mathematics Ohio Standards Alignment: Grades 7–10 Professional Commentary: Students collect data on their study and TV viewing time over a period of several days. They use a graphing calculator, with step by step instructions, to find measures of central tendency, construct a box and whiskers graph, construct a scatter plot of class data, and look for a line of best fit. Activity sheets and suggestions for assessment are included.... Resource Type: Instructional Resource -- Promising Practice Discipline: Mathematics Ohio Standards Alignment: Grades 8–10 Professional Commentary: This lesson is a data analysis lab in which students analyze mass and volume data for two mystery liquids, oil and water, and use the data to explore linear functions. Students relate slope and y-intercept to a real-world context.... Resource Type: Instructional Resource -- Promising Practice Discipline: Mathematics Ohio Standards Alignment: Grades 8–12 Professional Commentary: In this lesson, students model linear data collected in a variety of settings that range from car repair to sports to medicine. Students can work alone or in small groups to construct scatterplots, interpret data points and trends, and investigate the line of best fit.... Career Fields: Agricultural & Environmental Systems, Business & Administrative Services, Construction Technologies, Health Science, Manufacturing Technologies, Transportation Systems, General Career Skills Projects: Standards First Resource Type: Instructional Resource -- Best Practice Discipline: Mathematics Ohio Standards Alignment: Grades 8–10 Professional Commentary: This lesson is a data analysis lab in which students gather mass and volume data for two mystery liquids--oil and water--and then use the data to explore linear functions. Connections to science are an important part of this algebra lesson, which deals with density.... 8 Bungee Jumping With Toys Resource Type: Rich Problem, Inquiry, or Exploration Discipline: Mathematics Ohio Standards Alignment: Grades 8–12 Professional Commentary: Students determine the length of a bungee cord made of rubber bands that will allow a toy doll to fall as close as possible to the ground without hitting it. Teams of students collect data using cords of varying lengths up to 6 or 8 rubber bands.... 9 The Regression Line and Correlation: The Regression Line Resource Type: Content Resource Discipline: Mathematics Ohio Standards Alignment: Grades 8–12 Professional Commentary: In the first of four related activities (all accessible from this site), students work with bivariate data to investigate relationships between variables. The applet allows students to enter bivariate data on a coordinate grid using various scales.... 10 The Regression Line and Correlation: The Effects of Outliers Resource Type: Content Resource Discipline: Mathematics Ohio Standards Alignment: Grades 8–12 Professional Commentary: In the second of four related activities (all accessible from this site), students work with bivariate data to investigate relationships between variables. The applet allows students to enter bivariate data on a coordinate grid using various scales.... |
