Math Links for Week Ending Sept. 27th, 2013

I am not sure of exactly what applications this might have in the classroom and it does have some limitations but I think the interface is really smooth and nice.

I was watching the show Tanked (they make custom aquariums) and they did this neat thing where they had to make a martini glass so they cut a flat piece of plastic and then placed it on a form and baked it so that the plastic bent around the form to make the cone. It was very impressive. I tried to find the video but couldn't. I did, however, find a real company that makes these cones and they had a page on how they make them (including an Excel spreadsheet)

I think that the concept of functions might be one of those things that sometimes doesn't get the treatment that it should. Here is an interesting treatment that uses the analogy of using a vending machine. Take a look.

Here is a nice progression from similar lines to similar shapes.

As far as I am concerned, you can't have enough activities that show how improbable it is for someone to win the lottery. As it is with other Yummy Math activities, you have to be a member to get the solutions and an editable version of the activity. I particularly like the link to the app to simulate the powerball lottery.

I like this update of an older Dan Meyer activity dealing with the relationship between ticket cost and distance travelled/time taken for flights. A nice scatterplot/line of best fit activity. The main part of the update that I like is the use of Google docs.

Whenever I can introduce an algebraic concept by first using a numerical method I am happy. Apparently I am not the only one. Here is one dealing with the distributive property. Thanks to Dan Meyer for this one.

I really like this nice collection of Number Sense videos. Nine videos in all. Take a look at one of them below and the rest of them here

A nice little tidbit of data

Need some data about TV watching. Maybe after you see your favourite show
