Big Ideas: Data can be organized and displayed in different ways. The information in graphs can be used to answer questions about the data. Bar graphs and picture graphs can represent data in both similar and different ways. This lesson builds on students' work in second grade drawing a picture graph and a bar graph (with single-unit scale) to represent a data set with up to four categories. Also, students solve simple put-together, take-apart, and compare problems using information presented in a bar graph. This lesson is broken into two small parts; creating a bar graph using data about items to be placed in a beach day trip kit and a picture graph from information presented in a data table about items to include in an amusement park day trip kit. Students use the graphs they create to answer one and two-step word problems about the sample represented. Special Materials: OPTIONAL The students may use the included survey to collect real data and organize it into a data table before the task.
