This pair of 3 part lessons and activities allow you to guide your students through creating and reading scatterplot graphs. In the first lesson, they learn how to draw conclusions and identify trends. In the second lesson, they learn how to use the data about two different variables to create and plot points on a scatterplot. Next, they analyze the results and identify the relationship between the two variables.

Ontario Math Curriculum Expectations:

D1.1

identify situations involving one-variable data and situations involving two-variable data, and explain when each type of data is needed

D1.6

analyse different sets of data presented in various ways, including in scatter plots and in misleading graphs, by asking and answering questions about the data, challenging preconceived notions, and drawing conclusions, then make convincing arguments and informed decisions

D1.3

select from among a variety of graphs, including scatter plots, the type of graph best suited to represent various sets of data; display the data in the graphs with proper sources, titles, and labels, and appropriate scales; and justify their choice of graphs

This problem-solving approach provides students with the opportunities to apply reasoning skills, select tools, problem-solving and computational strategies, create a variety of representations of mathematical ideas, communicate and defend their ideas, and reflect on and monitor their thinking.

WHAT'S INCLUDED

• Tips Sheet: This detailed guide will provide you with a breakdown of each part of the lesson.

• Getting Started: Your students will be lead through an activity that helps them determine trends and important information listed in scatter plots.

• Working On It: Two rich problem-solving tasks in which students can work with a partner, in a small group, or individually. Task #1 requires students to match 6 different scatterplots with their missing titles and justify their reasoning. Task #2 has students guess what 3 different labelless scatter plots could be comparing based on the direction of the data they show.

• Exit Ticket: Each student will complete the exit ticket independently. This work is used for assessment purposes and allows the teacher to identify common misconceptions or areas of need. It is also a great opportunity for the teacher to provide individualized descriptive feedback.
