Our new graded-series of maps are the first to address the unique needs of K-12 students as they advance their understanding of our World. Unlike other classroom poster maps, ours utilize the Winkel-Triple projection, which provides the best combination of size, shape, and distance giving the student the best visual representation of the Earth"s surface. This solves the effect seen on other maps where Greenland appears larger than South America. As kids progress, so do our maps! Our Political Series, grades 4-12, has up-to-date World and U.S. maps, increasing the detail of information for the teacher and student to utilize. Map is printed on premium quality paper stock, rolled, and wrapped in kraft paper without display packaging.Sheet Size = 51 x 40Scale = 1:4,286,000
