MA19.3.16

Mathematics (2019) Grade(s): 3

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.

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.

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.
