I love this project, and most students do too. The math teacher on my team also loves it, because we use x/y values on the coordinate plane to make our sidewalk chalk creations.
After your instruction on the events of the Cold War, this project asks students to choose one major event from the period. Next they select a map or image of their choice and copy/paste it on the provided x/y axis graph. Students then collect data points for their picture. We then use these data points to 'connect the dots' creating some pretty awesome sidewalk chalk creations. Other classes get crazy jealous - you look super cool, and kids learn to boot!
