Read and Scale a Data Graph
Pictographs, bar graphs, and line graphs encode values through a scale — symbol value or grid-square value — that must be read before any total, difference, or comparison is computed. Learners translate between tables and graphs, choose scales, read double bars and two line graphs, and estimate intermediate values. Decoding the scale is the load-bearing step at every grade.
