Common Core Math · Grade 1
1.MD.C.4 Organize and interpret data in up to three categories
Organize, represent, and interpret data with up to three categories; ask and answer questions about the total number of data points, how many in each category, and how many more or less are in one category than in another.
Why water teaches this standard well
Students survey classmates on whether they drink tap water, bottled water, or a water fountain most often, then organize the tally into three categories and answer how many more chose tap than bottled. Turning a real preference into a simple data question is an early taste of the water-use surveys students will run in later grades.
Materials tagged with this code are written to the full standard , and each carries a written note explaining the alignment. See how we review materials.
