"If you watch this gif for around 1 1/2 minutes, the Volume of that brick would have reached that of the known (observable) universe!"

"Mark talked about the idea of using Evidence-Based Arguments as a starting point. Every historical investigation needs to begin with a great question. Then they asked kids to do research and create videos. But what they got was disappointing. What they got was basically text with pictures, a script with a background. It wasn't a story, it wasn't engaging, and it often didn't really answer the question.  They begin to realize that they needed to learn more about how to create high-quality documentaries, how to use images and video to actually tell a story. And eventually they came up with a Four Step Process that students work through to create high-quality documentaries:" 4 Step Process for creating HST videos. I don't necessarily agree with the author's thought that tech should not be introduced until step #4, as tech can enhance 1-3 just as well. The teacher just needs to model good behavior and help students develop structures for the work in these phases for it to be successful.

"There's a contest called Math-O-Vision, which your students should enter. Here's the premise: The Neukom Institute for Computational Science, at Dartmouth College, is offering prizes for high school students who create 4-minute movies that show the world of equations we live in. In 240 seconds, using animation, story-telling, humor, or anything you can think of, show us what you see: the patterns, the abstractions, the patterns within the abstractions." Two interesting things going on in this short blog post: 1. It introduces a contest which might be interesting for some of your students. I looked at the winning video from last year (linked in the post) and know that our students are capable of making something of similar quality. 2. The articles provides an interesting insight on math as a "product." This is quite an interesting discussion when thinking about how/why to assign this type of activity to your students.

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.

I'm sure this map holds a ton of possibilities that I know I'm not seeing immediately. Here are some things I am thinking: 1. Where is the windiest/least windiest location on earth? Why is that the case? 2. Where would be the ideal place to put a "wind farm?" 3. Let's check out that hurricane that's developing...

"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.

For Will Berry

Hah. Awesome. Here are a few more specifically for middle school literature: 1. Divide the number of pages in your novel by the number of chapters it contains. The average should be equal to or less than your intended audience's age. 2. Determine the ratio of action verbs to any other verbs. If the ratio is less than 5:1, include more crazy twists and scenarios to keep the attention of your reader. And most importantly... 3. The number of characters in your novel that are either vampires, werewolves, or zombies should exceed that of all humanoid characters. If not, revamp your story to comply with current fad.

Google Maps- new version

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).

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.

An interesting model for novel reflection in general and vocabulary specifically. "Favorite passage: "The urbane activity with which a man receives money is really marvellous, considering that we so earnestly believe money to be the root of all earthly ills, and that on no account can a monied man enter heaven. Ah! how cheerfully we consign ourselves to perdition!" Words looked up: Mole (As in "downtown is the battery, where that noble mole is washed by waves ..."): A massive, usually stone wall constructed in the sea, used as a breakwater and built to enclose or protect an anchorage or a harbor. Decoction: An extract obtained from a body by boiling it down. Orchard thieves (Melville refers to having to pay for things as "the most uncomfortable infliction that the two orchard thieves entailed upon us."): I have no idea what this alludes to. Update: D'oh! I am dumb. I (repeatedly) misread this as "orchid thieves," no doubt because I recently read the book of the same name. Yes, the meaning of "orchard thieves" is clear."

"There is a new digital divide on the horizon. It is not based around who has devices and who does not, but instead the new digital divide will be based around students who know how to effectively find and curate information and those who do not."
