Math Links for Week Ending Oct. 4, 2013

If you love billionaires sailing around in multi million dollar carbon fibre rockets then the latest America's Cup challenge is for you. These AC 72 yachts are a technological marvel. Truly amazing how they literally fly above the water. But even better is that there is full coverage online with lots of extra features. In this segment they give a nice real world application of adding vectors when dealing with the apparent wind ( the direction the wind feels like it's coming from which is the vector sum of the actual wind and the wind generated from movement )

Is post secondary education worth it? We have seen some of this data in previous weeks. In this version we have the connection with tuition and earnings. It interesting how the connection between these things is different depending on the type of institution. Now this is based on US schools where, in my opinion, there is a very wide swoth of quality ( whereas here in Canada I think the quality is pretty high regardless of where you go )

Even though this blog post is about the social value of giving the same activity over several years, one of the comments ( from Mr. Stahl) actually inclded a link to the actual matching cards that you can download and print out here Even though this is a matching activity dealing with radians it could be adapted to grade 11 trig.

Another one from the blog Math Teacher Mambo for trig. This time on reference triangles. I like two things about this 1) the investigative nature of the activity and 2) using whiteboard markers right on the surface of desks. No you can't lift up your desks to show the class like with portable white boards but the trade off is you have a huge surface for solutions.

Although there is some discussion here about the value of teaching domain and range (in the comments), here in Ontario it is a specific part of the grade 11 curriculum. So this yes/no card activity would work well.

I am a sucker for a good infographic ( I'm kinda dumb that way). Here's one that Yummy Math is using that asks the question "is there a home field advantage in the NFL?" As it is with all activities on this site, the PDF is available to download but you need to be a member to get the answers and a editable version.

For those of you who like Vi Hart, you can see tha the apple doesn't fall that far from the tree. Here is a video from her dad about his exhibit of geometrical art. On a side note, if you google his name he comes up as a professional geometer. Who knew that was a thing?

The art of data visualization (nuff said)

I thought this graph would be a great discussion starter for two reasons. 1) because the discussion of which person is better could actually be fairly deep and 2) you can use it to re enforce the idea of how to place points on a scatter plot ( maybe you could ask where a good person would be place d on the graph?
