ESSENTIAL QUESTIONS How are tables, bar graphs, and line plot graphs useful ways to display data? How do I decide what increments to use for my scale? How can graphs be used to display data gathered from a survey? How can graphs be used to compare related data? MATERIALS in the Data Part student recording sheet “It’s II” Plain paper Large container of small objects buttons, blocks, marbles, or Unifix cubes, or similar – object Chart Paper and Markers Ruler/tape measure Paper, markers, crayons, rulers and other supplies needed to create graphs by Stuart J. Murphy, or a similar book Lemonade for Sale GROUPING Small Group Task NUMBER TALKS By now number talks should be incorporated into the daily math routine. Continue utilizing the different strategies in number talks and revisiting them based on the needs of the students. TASK DESCRIPTION, DEVELOPMENT AND DISCUSSION (SMP 1, 2, 3, 4, 5, 6, 7, and 8) Part I Line plot graphs (sometimes called dot plots) are an excellent way to display data in an easy and quick manner. Line plot graphs in third grade are used to record measurement data to the nearest ¼ inch. Students should use the following questions to generate measurement data for a line plot graph: How tall are your classmates to the nearest ¼ inch? What is the arm span of your classmates to the nearest ¼ inch? How long are your from the tip of their finger to their wrist to the classmates’ hands nearest ¼ inch?
