For a given or collected set of data, create a scaled (one-to-many) picture graph and scaled bar graph to represent a data set with several categories.

Unpacked Content

Knowledge

Students know:
  • Strategies for collecting, organizing, and recording data in picture graphs and bar graphs.
  • Describe and interpret data on picture and bar graphs.
  • Strategies for solving addition and subtraction one-And two-step problems.

Skills

Students are able to:
  • Collect and categorize data to display graphically.
  • Draw a scaled picture graph (with scales other than 1) to represent a data set with several categories.
  • Draw a scaled bar graph (with scales other than 1) to represent a data set with several categories.
  • Determine simple probability from a context that includes a picture.
    Example: A bar graph displays data to represent students' favorite colors with data showing 4 students choose red, 11 students choose blue, 2 students choose green, and 4 students choose purple. If Jamal is a student in the class, what do you think his favorite color might be? Why?
  • Solve one-And two-step "how many more" and "how many less" problems using information presented in scaled graphs.

Understanding

Students understand that:
  • Questions concerning mathematical contexts can be answered by collecting and organizing data scaled pictographs and bar graphs.
  • Understand that logical reasoning and connections between representations provide justifications for solutions.
