Graphs, Charts, and Tables

Grade 3 data work extends to multiple representation types: bar graphs, pictographs, charts, and tables. The key skill is choosing the right type for the data: categories compare well in bar graphs; changes over time show well in line graphs (introduced later); tables show exact values clearly. One-to-one correspondence remains the foundation: each item in the data corresponds to exactly one unit in the representation, whether a bar length, a picture, or a table cell.
