Standards Addressed:
Grade three
Investigation and Experimentation

• 5c. use numerical data describing and comparing objects, events, and measurements
• 5e. collect data in an investigation and analyze those data to develop a logical conclusion

Grade Four
Investigation and Experimentation

• 6e. construct and interpret graphs from measurements

Mathematics: Statistics, Data analysis, and Probability

• 1.1. formulate survey questions; systematically collect and represent data on a number line; and coordinate graphs, tables, and charts.

Grade Five 
Investigation and Experimentation

• 6g. record data by using appropriate graphic representations (including charts, graphs, and labeled diagrams) and make inferences based on those data

Mathematics: Statistics, Data analysis, and Probability

• 1.1. know the concepts of mean, median, and mode; compute and compare simple examples to show that they may differ.
• 1.2. organize and display single-variable data in appropriate graphs and representations (e.g., histogram, circle graphs) and explain which types of graphs are appropriate for various data sets.
