william berry on 03 Oct 13This seems like a fun and interesting way to discuss/learn several different math topics. Here's a sample lesson plan that popped into my head when I saw this post: 1. Show to students a GoogleMap/GoogleEarth image similar to the one on the website, but more meaningful to you/them. For example, several different grocery stores around your house. 2. Ask the students, "Which one should I go to?" Have the students justify their answers using the image and mathematical topics that they have learned up to this point. 3. With appropriate questioning you could work in several mathematical topics here (I know I'm missing others as well…) a. Overlay a grid on the GoogleMaps and have the students give each of the locations points on an x,y axis. Use this information to determine distance. Have a conversation if this is the best way to determine which location is easiest to access. When students start to bring up the fact that even though some points are technically closer, but could be slower to get to, bring in… b. Rates, ratios, etc. Discuss how fast you could possibly travel on each route according to number of stop signs, streetlights, speed limit etc. Have students use this information to calculate the appropriate answer.
