"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.

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).

""That's why the goal of school has to be automaticity," my dad concluded. The Sunday morning roads were empty, and we'd nearly made it home. "Take learning your times tables. You've got to know them cold so that you can go on to finding common denominators, or reasoning about algebraic functions, or whatever. You need each task to become automatic before you can move onto the next intellectual step."" Humorous, yet enlightening take on math class, which can be applied to school in general. What is more important for us to teach students so that it becomes more automatic? Should we make facts automatic? Or should we instead focus on skills and thought processes that can be quickly applied to many scenarios in a variety of contexts?

I saw this Dan Meyer TED Talk on re imagining Math through problem solving. I like how he takes a problem from the textbook and makes it more rigorous. "Today's math curriculum is teaching students to expect -- and excel at -- paint-by-numbers classwork, robbing kids of a skill more important than solving problems: formulating them. In his talk, Dan Meyer shows classroom-tested math exercises that prompt students to stop and think. (Filmed at TEDxNYED.)"

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

"When I get a taxi for the 15-minute ride from my office to the airport, I have two choices. I can hail a cab on the street, and pay a metered fare for the 4.6-mile trip. Or I can walk to the local Marriott and pay a fixed fee of $31.50. Truthfully, I'm always a lot happier paying the fixed fee. I'm happier even though it probably costs more in the end. (A congestion-free trip on the meter comes out to about $26.) Sitting in a cab watching the meter tick up wrenches my gut: Every eighth of a mile, there goes another 45 cents-tick ... tick ... tick." ...this provides interesting context for a math problem using linear equations. When is it worth it to pay the fixed fare vs. paying the per 1/8th of a mile rate? You could "3-Act" this scenario pretty easily: -Take a short video of a taxi fare display clicking upwards. Ask students to give you the first questions that come to mind. When the students ask for it, provide them with a photo of the rate schedule on the side of the taxi and your destination address.
