Draw a scaled picture graph and a scaled bar graph to represent a data set with several categories. Solve one- and two-step “how many more” and “how many less” problems using information presented in scaled bar graphs. For example, draw a bar graph in which each square in the bar graph might represent 5 pets.

[divider] [/divider] Students are able to… 

  • Collect data and draw a picture or bar graph.
  • Analyze and explain data from a picture or bar graph.
  • Solve “how many more” or “how many less” problems using a bar graph.

[divider] [/divider] Students are able to…because teachers:

  • Provide opportunities for students to collect a variety of data.
  • Model precise vocabulary and how to organize and display data in a picture or bar graph.
  • Pose questions so that students analyze data and solve problems using “how many more” and “how many less”.

 [divider] [/divider] Questions to ask students:

  • If you were making a bar graph, what important parts would you include?
    • Sample answer that indicates understanding: You would need to make a title, scale, scale label, categories and label for the categories. Then you can add the data.
  • Why is a key important when analyzing a picture graph?
    • Sample answer that indicates understanding: A key lets the reader know the value of each picture on the graph. For example, if the key says each picture equals 3 then I would need to count by threes to find the total in that category.
  • Have students use a bar graph to compare 2 categories by asking how many more or how many less is one category than the other.

Cognitive Complexity Level: 2 – Basic Application of Skills and Concepts

Achievement Level Descriptors:

2- solves one-step problems using a given picture or scaled bar graph (with a scale factor of 1 or 5)

3- creates a scaled picture graph and a scaled bar graph to represent a data set; solves two-step “how many more” and “how many less” problems using information presented in scaled bar graphs

4- completes a scaled picture graph by using addition and subtraction to find missing data values

5- creates a scaled picture graph or a scaled bar graph to represent a data set and determines what the scale factor should be; draws conclusions when analyzing data

Assessment Limits:

The number of data categories are six or fewer.

Items must provide appropriate scale and/or key unless item is assessing that feature.

Only whole number marks may be labeled on number lines.
