Cool lesson idea for pythagorean theorum and ratios. Includes already-made geogebra apps for the lesson so that students can manipulate the size of the TV in order to respond to teacher questions.

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.

"Teachers: A Simple (Not Easy) Pedagogy Assessment" A lot of these questions could lead to interesting discussions with teachers.

"If teachers don't have enough time to ask, answer, reflect on, and revise their thoughts about the questions above, then we shouldn't be filling their time with things other people get paid to do, like writing curriculum, writing fancy-schmancy benchmark tests, looking at data that's not useful on the individual student level, or discussing which minutes of the day the bathrooms will be open to students." So many things going on in this article...Personally, I found this statement to be the main standout. I agree with this completely - instruction comes first and all the rest is secondary. If you do a great job with instruction, many of the other time eaters/wasters should fall into place and take care of themselves naturally.

"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.

A friend shared this with me and it's a good read. It also summarizes the way that many of our teachers think, and could be an interesting article to share with a teacher and have a discussion about. Ultimate, I have a huge problem with the assumptions and conclusions that are being made here: "Now I'm not calling for abuse; I'd be the first to complain if a teacher called my kids names. But the latest evidence backs up my modest proposal. Studies have now shown, among other things, the benefits of moderate childhood stress; how praise kills kids' self-esteem; and why grit is a better predictor of success than SAT scores. All of which flies in the face of the kinder, gentler philosophy that has dominated American education over the past few decades. The conventional wisdom holds that teachers are supposed to tease knowledge out of students, rather than pound it into their heads. Projects and collaborative learning are applauded; traditional methods like lecturing and memorization-derided as "drill and kill"-are frowned upon, dismissed as a surefire way to suck young minds dry of creativity and motivation. But the conventional wisdom is wrong. And the following eight principles-a manifesto if you will, a battle cry inspired by my old teacher and buttressed by new research-explain why." Why are these seen as two completely different and opposing philosophies of education? That's my question. From my experience, teasing knowledge and understanding out of children stresses the hell out of them. They struggle to give you an answer initially, but when when you are unwilling to spoon feed them or provide them with a "drill and kill" answer, they finally make a connection. In doing so you show the students that their grit and determination has helped them gather a better understanding of the material and become a better student and learner in process.

I may write a decent response to this. She plays just about every false argument card in the book. It needs this treatment - http://www.al.com/opinion/index.ssf/2013/10/huntsville_teacher_common_core.html

This take down of Gladwell's dyslexia chapter http://languagelog.ldc.upenn.edu/nll/?p=8123 makes for a similar parallel.

"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.

How can a game help students develop mathematical habits of mind? "Then we talked about the game for a bit, and discussed the "habits of mind" they had employed to figure out the game - noticing and wondering, guessing and checking, persevering, struggling productively, learning from mistakes without worrying about making mistakes (since they knew the only way they were going to make progress was to make mistakes and learn from them), and working together. We talked about how these skills are as important as any content they learn in their school classes, and how they can use those skills to make progress on math problems they're not sure how to solve. In fact, much of the math programming we did the rest of the year employed huge doses of Noticing and Wondering and generating ideas about math situations, or scenarios (a math problem with no stated question). Anecdotal reports suggest that by the end of the year, most of the students felt pretty confident that they could generate ideas about most math situations we handed them. Big win!"

"When we sit down to try thinking up new ideas, it doesn't feel like we're connecting things. It feels like a strain-like you're trying to create something out of nothing. But the truth is, ideas really do come from connections." Intereresting article that can be applied to the way teachers plan AND the experiences that students have in the classroom.

If any of these questions seem interesting, you may want to watch listen to the interview.  It reminded me of the Student-led TED Talks I saw at GAHS this spring. * What makes for a good TED talk? * Do you have an example of a TEDster who greatly improved their talk? * What makes for a really bad TED talk? * How do you deal with someone who does not think they need to improve? * Do you think there is a real value to the short-form, "TED Style" talk?

"Press the play button below to watch the war unfold over time. Drag the scrubber or click on the months and years to change the date range. Roll over the circles for more information on each battle. Casualties are defined as killed, wounded, missing and captured." Cool visualization of all Civil War battles. A couple questions that couple be useful when students view this timeline: - Using the available data, explain the Union strategy during the war - Using the available data, explain the Confederate strategy during the war. - Using the available data, explain what event/series of events represents the turning point of the war.

"Empower your students to think critically about data, ask meaningful questions, and communicate their conclusions."

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).

"Add "Would You Rather?" to your bookmarks. Phrasing math problems in terms of "Would You Rather" is simple and brilliant. I love this framework for three reasons:" Interesting framework for solving math problems. This post links to a resource of "Would you rather" problems that could be useful in a variety of different math courses.

Another resource for supporting student reflection.
