The document discusses how height is shown on maps using contour lines and spot heights. Contour lines are thin brown lines that represent 10m of height on a map. Closely spaced lines indicate a steep slope, while lines farther apart indicate flatter land. Students are instructed to complete activities matching letters to numbers, making landscape models using provided materials and colors to represent different heights, and answering height questions based on contour lines and spot heights on a sample map.
