"The best long-term strategy I can see for continuously getting better is for the process of improving to be fun. If I want to get better at teaching, it's got to be fun for me to do so, because that's the only way for me to stare down the abyss of my current craptitude and the probability of my own immediate failure. That's going to look different for different people, because we've all got different tastes. I enjoy planning lessons, so I spend a lot of time on that. You like giving feedback, so you spend your time on that and you get great at that. I hate it, so I suck at feedback and am decent at curriculum." Agree completely with this statement. I think this holds true for our students too. The best long term strategy for improvement in school is that kids needs to have fun in the process.

"I guess dragons love gold. In the recent trailers for The Hobbit: The Desolation of Smaug (YouTube clip) you can get a glimpse of all the gold Smaug has. Why does a dragon need this much gold? I don't get it. Maybe Smaug doesn't actually like gold but he just wants to keep it away from other people. Whatever his motivation for hoarding, I am going to try to get an estimate for just how much gold is in the Lonely Mountain." Talk about a fun math problem...

"Too often kids have trouble with word problems. Too often they don't know what to do with two numbers let alone a bunch of numbers. They guess at division when one number is big and one is small. They add when they see two fractions. They multiply because that was how they solved the last word problem. I will also do this with my 8th graders because I suspect they will have trouble too. And this is exactly the kind of trouble we need to get into. Now rather than later. This task gets them thinking about ratios - which is like the most important math thing in all of the math things." This is a short description of how to get your students developing questions for mathematical scenarios. This would be a great activity to work on if you feel like your students are having difficulty deciphering word problems or are stumped when presented with unfamiliar mathematical scenarios.

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).

"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.

"This resonates strongly. I shared a lesson with fellow teachers, and realized I had no good way to communicate what actually made the lesson powerful, and how charging in with the usual assumptions of being the explainer in chief could totally ruin it." Couldn't say it any better than this...Personally, this is one of the reasons I've tried to get video of classroom action and student reflections over the past several years for H21. We can write all we want about what makes a lesson powerful, but it's much more obvious and useful when we see it/hear it ourselves.

There are a lot of great problems here that could be used in math class. Starting class with one of these problems could be a great way to hook students into the lesson and have the students start generating their own questions and problem solving methods. Then, the math can be brought in appropriately. A lot of these problems seem to lend themselves to the "3 Act Task" model. A video/image representing the problem could go a long way in getting kids hooked.

"The strategy that has worked best for me over the years has been to create a non-threatening atmosphere in which teachers can experiment and explore without repercussions as they become more familiar with technology tools. The key is to cultivate a climate of discovery and experimentation as opposed to one of judgement and unattainable standards. After all, we don't expect our students to be perfect the first time around. We encourage them to experiment and take risks. If everything had to be perfect right away, we'd never get anything done!" Interesting post to share with teachers

"David Cox sent his students through Function Carnival where they tried to graph the motion of different carnival rides. (Try it!) Every student's initial graph was wrong. No one got it exactly right the first time. But Function Carnival doesn't display a percent score or hint tokens or some kind of Bayesian probability they'll get the next graph right. It just shows students what their graph means for that ride. Then it lets them revise."

""I think competitive character people don't want to be manipulated constantly to do what one individual wants them to do," Popovich said, "It's a great feeling when players get together and do things as a group. Whatever can be done to empower those people."" Applications for classroom and for our job as ITRTs. ...and I just love Popovich.

This is a pretty powerful Ignite Talk. Might be a good resource to get teachers pumped up for the year.

"How did Gladwell misconstrue it? Aside from not having copied the numbers from the actual paper correctly for his book? He says that there is a perfect correspondence between practice and the level of expertise a person attains. And you can't tell that from the paper. The 10,000 hours is an average of differences. You could have two people in any endeavor and one person took 0 hours and another took 20,000 hours, which is something like what happened with two high jumpers I discuss in the book. One guy put in 20,000 and one put in 0, so there's your average of 10,000 hours, but that tells you nothing about an individual. Now, Gladwell doesn't say there's no such thing as genetic talent. I think other writers are stricter than him. [Matthew Syed's] Bounce is a book that minimizes talent. Gladwell does say elite performers are more talented. One of the things that Ericsson criticizes Gladwell about is to say that 10,000 hours is some kind of rule. The paper just says that these performers by the age of 20, these performers have accumulated 10,000 hours but there's no where that says it's a magical number where that's when they become elite or anything like that. These people, by the time they go into their professional careers, have way more than that. That's just where they were when they're 20 as an average, not even to mention their individual differences."

""What's the sine of π/2?" I asked my first-ever trigonometry class. "One!" they replied in unison. "We learned that last year." So I skipped ahead, later to realize that they didn't really know what "sine" even meant. They'd simply memorized that fact. To them, math wasn't a process of logical discovery and thoughtful exploration. It was a call-and-response game. Trigonometry was just a collection of non-rhyming lyrics to the lamest sing-along ever. Some things are worth memorizing--addresses, PINs, your parents' birthdays. The sine of π/2 is not among them. It's a fact that matters only insofar as it connects to other ideas. To learn it in isolation is like learning the sentence "Hamlet kills Claudius" without the faintest idea of who either gentleman is--or, for what matter, of what "kill" means. Memorization is a frontage road: It runs parallel to the best parts of learning, never intersecting. It's a detour around all the action, a way of knowing without learning, of answering without understanding."

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.

"Just a quick post- we started a unit on percents today.  Found this activity from Illuminations, but I needed it to be a little bit more.  The activity takes the BMIs and weights of season 14′s contestants and students need to find the percent lost for each in order to find out who won the game.  We then had a discussion on why the show does not award the prize to the person with the most weight lost, but the highest percentage." You could find some good video/media to go along with this to hook students - Maybe a before/after picture video which I'm sure you could find online. Have the students use the video to predict the winner then get into the worksheet. There are some pretty good extension activities embedded here as well: Research how BMI is calculated, Determine whether percentage of weight lost is the best method to determine the winner, etc.

"The Web Literacy Standard is a map of competencies and skills that Mozilla and our community of stakeholders believe are important to pay attention to when getting better at reading, writing and participating on the web. "

"And yet no one I'm aware of has pointed out one of the more glaring (literally) problems with Jackson's Tolkien films, a problem that has become more evident to me with each installment. It's the choice of his own native land, New Zealand, as the backdrop for these British stories. The island nation of swooping hills and glistening peaks isn't merely an unfortunate choice-it's one of the worst options I can imagine." You could do some really interesting textual analysis stuff like this with comparing book characters and settings with their on screen counterparts. What holds up to the original? What has changed? How does that affect the reader/viewer or change the message of the story? There's plenty of options that students would get into - The Hunger Game Series, The Hobbit, you could even do comic book characters and their on screen counterparts.

"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 place where I was playing around with aggregating interesting word usage, writing prompts, poetry etc. It might be a model for larger groups or for students which is where it'd get interesting.
