Big Ideas: Symbols on a picture graph represent data. Answering questions about data in a picture graph helps us to understand the information. There are various ways to solve a one and two-step word problems. Two-step word problems using “how many more” and “how many less” can be solved using the data from graphs and tables. 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. In this lesson, students work with data collected at Clearwater Elementary School to determine the cost of putting together kits to sell for day trips to the beach and the amusement park. Students use the graphs to answer one and two-step word problems about the sample represented. Vocabulary: bar graph, picture graph, survey, data, total cost
