3 Guided Practice: Direct students to the “Misleading Graphs” box on page 62 of the student handbook. Read through the introduction and ask students the example questions listed. • Are there any other graph types that might work for this data? Why? (circle graph; Answers will vary. ) • Ask students to compare the two bar graphs by asking: How does the bottom bar graph fix what is misleading in the top bar graph? (The y -axis of the bottom bar graph begins at 0.) • How does correcting the scale of the y -axis change the way a person might interpret the graph? (The difference between the scientist bar and the athlete bar does not look as severe in the bottom graph.) • Last, divide the class into pairs and have them complete one or more of the “Your Turn” problems, using the diagram to find the inaccuracies in the graphs that follow. When students have finished, have them share their answers as a group. 4 Reflect: Ask them to respond in writing to the following questions: Are you concerned about fake news? After students have finished writing, engage them in a structured group discussion. Call on volunteers to read their responses. 5 Group Activity: Go to “Deceptive Data” on page 64 of the student handbook. Divide the class into teams and assign each team one or more problems to solve. When students have finished, ask each team to talk through its answers. 6 Quick Check: Have students complete one of the Exit Slips on page 67 of the student handbook. A: On Level; B: Advanced. 7 Additional Practice • “Drawing a Circle Graph,” pages 65–66 of the student handbook. Students follow steps to draw circle graphs, and on page 66, complete tables and associated circle graphs.
