Big Ideas: Data that can be measured can be represented. Measurement processes are used in everyday life to describe and quantify the world. Charts and graphs can help make solving problems easier. This lesson builds on the students' work with collecting and sorting data. This task uses the pretense of two students, Alexis and Jakob, picking up and sorting litter from their playground. Students are asked to grab linking cubes to represent litter. Students will record their data on a table and create a bar graph display. As students compare their representations in the lesson debrief, they will discover the necessity and benefits of common graphing conventions. The mathematical concepts in this lesson build toward students' future work with drawing and solving word problems including picture and bar graphs. Vocabulary: table, representation, data, category, bar graph, vertical, horizontal, axis, total, count (referring to a total of a group) Special Materials: Table Template Grid Paper Red, Blue, Green and Yellow Linking Cubes (enough for each student to have handful) Crayons or Markers Optional: Blank paper Chart paper Actual pieces of litter
