Ask simple questions about one attribute, sort objects into categories, collect categorical data, and record counts using tally marks or simple tables. Create and interpret one-to-one pictographs and simple bar graphs with small whole-number counts, identifying the most and least common categories and comparing two categories as more, fewer, the same, or how many more or fewer. List possible outcomes, conduct simple chance experiments, record results, and describe events as certain, possible, impossible, likely, or unlikely using informal language.
