This 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.

This is the Newest webtool developed by Dan Meyer and Dave Major. Dan Meyer discusses the tool and task in a post on his blog here - http://blog.mrmeyer.com/?p=17503 I think this tool would be very engaging for students. Give them the task of finding the quickest route, and they will go nuts with it. I see two main applications for this particular tool/task: You could use this tool as an introduction to angles. Put it on the board, give the kids the task, and have them discuss how they would tell the ship captain to navigate around the buoys. When non-mathematical language and vocabulary bogs down the ship's progress, overlay a grid/protractor and introduce the idea of angles. Have the kids play around with the tool to come up with the quickest route. Discuss the result of small differences in angle measurement on the ship's progress (each degree above the necessary increases the amount of time lost). This could lead into a discussion on the importance of precision… This would be an easy task to make over if you wanted to talk about slope and writing equations of lines (Algebra I). You could overlay a grid on the board, The kids could draw the lines in to get the ships around the buoys, write the equations, then you could talk about how cumbersome the equations are and how ships are actually piloted and bring in the idea of degrees/vectors (direction and angle). Not only does this tool help to teach angles/vectors, but it's also a tool to get students estimating (angles AND distance).

Lesson objective: In this lesson, students use coordinates to compute perimeters of polygons and areas of triangles and rectangles, e.g., using the distance formula. Pretty much all the steps to this lesson are on the website, which also includes a download link with all the materials that you will need. Something to think about if you plan on completing this lesson: When you first pose the problem to the students - Have the students discuss how they could represent the location of the different vertices for the Bermuda triangle. Give the students time to research/explore and find the latitude/longitude on their own rather than giving it to them directly. There are plenty of tools out there that can help the students complete this task, the most common being Google Earth and Google Maps

"Twitter has offered me an intellectual community I otherwise lack. It cuts the distance, both geographic and hierarchical. Not only can I talk with people in other places, but I can engage with people in different career stages as well. A sharp insight posted on Twitter is read, and RT'd (retweeted), with less regard for the tweeter's resume (or gender or race) than it might be if uttered at, say, a networking event. Social media is a hedge against the white-shoe, old-boys' networks of publishing. It is a democratizing force in the literary world."

"In my honors Algebra II class of sophomores, I always look forward to doing a culminating project on quadratics.  We start at the beginning of the chapter with introducing the project and having the kids break up into groups of 3 and 4 and start designing and building a catapult outside of school.  " This seems like a fun activity that could be enchanced by Logger Pro and/or Desmos (www.desmos.com). Logger Pro would allow the students to video a sample shot of their catapult and then break down the distance of their shot at specific intervals/times. Desmos would allow the students to graph the quadratic and place their catapult at the correct location in order to hit their target.

"As brilliant reader John D. asked, how many miles does Mario have to travel before he finally gets to Princess Peach?" This could be a great lesson starter for ratio, proportion, and estimation. Show your students one of the levels, ask them to predict, and then have the students create a process in order to answer the question. Reveal the article after students have made their calculations.
