Ready to lose whatever time remains in your work day? This cute little cat will mess with you. Good luck in Circle the Cat.
Estimation 180 is a great site for building estimation skill. I can see using this at the beginning of class to stimulate thought. Best of all the site works great on mobile devices.
This is crazy. There are no shortage of sites that let you set up and manage a class online for free. Eduongo is a site that lets you set up and manage your own SCHOOL. Imagine opening your own school being as easy as starting a blog. I have no idea how good Eduongo’s platform is, but it is a clear continuation of a trajectory of digital education. It is only a matter of time before there are others. I’m not sure whether to be excited or afraid? Check out their promo video below.
One thing that I notice is particularly hard to impart in my online classes is mathematical vocabulary. My online students can be very technically proficient in key skills without being able to talk about them very well. I always notice this when they come in for office hours and we’re talking about a particular problem. I’ve been brainstorming different ways to develop vocabulary remotely. Here is my latest. I’m not sure what the name for these are. (Guessing: pictogram?) But we’ve all seen these in different games. You have a series of pictures indicating a word. See if you can guess these? And let me know what you think of the exercise.
Math Trail is a really interesting idea. It is an math themed scavenger hunt using google maps. There are different hunts you can do and they are centered on different mathematical themes. Check out the demo.
Units have been going through my mind a lot lately. I ran into this on Futility Closet. It made me speculate what a Hendree unit might be? Doesn’t everyone deserve a unit named after them? Any suggestions?
This is a cute Numberphile to use with your students. It is a short fun episode that explains the math behind some of the most common math jokes.
I will always remember reading the book Cadillac Desert. It was the first book that I read that was vividly able to contextualize really large numbers. Seeing this awesome new chrome extension reminded me of that experience. The Dictonary of Numbers will take any number you find on the internet and do exactly that for you: contextualize it. Check out the video.
I found this extension via my favorite tech tools blog: Free Technology for Teachers
