The dot can represent one count or object, or a unit of objects (e.g., one dot=10 houses).

Most of the spatial data visualizations students will encounter in social studies are maps, but not all maps are the same, and not every map fulfills the same function. In addition, some of the spatial data visualizations students might encounter represent humans' efforts to map out stars and planets, caverns and tunnels, or parts of the human body. plain 2021-06-21T15:33:49-04:00 Benjamin Steinig 74775bc5c03628537e0192f4b5deec6811d610f6
