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.
