A Map of the Cables Connecting the World

TeleGeography has produced a couple of interesting maps of the telecommunication cables that cross under oceans and seas. The interactive Submarine Cable map allows you to click on various points and lines to see the locations that they connect. The map also shows you who owns the lines depicted.

A poster (infographic) version of the Submarine Cable map is available too. The poster version includes a timeline of cables connected between 1997 and 2012.

Applications for Education
Students today grow up just assuming that the Internet connects everyone, but they probably don't think about how that actually happens. These maps could be a nice way to show students how much cable it takes to connect us. An extension of this would be to have students try to calculate or research how many miles of cable are under an ocean or sea.

Add Prezi Presentations to Your Knowmia Lesson Library

Knowmia is a free service that offers a huge library of videos and presentations for flipped lessons. The library is generated by the contributions of teachers. Users of Knowmia's free Knowmia Teach iPad app can create their own flipped lesson videos and submit them to the Knowmia library. I recently learned that you can also submit your Prezi presentations to the Knowmia library.

To submit a Prezi presentation to the Knowmia library all that you need to do is copy the URL of your Prezi and paste it into the "import lesson" field in the myKnowmia tab in Knowmia. Screenshots of the process are available here.

Multiplication.com - Games and More for Practicing Multiplication

When I was in elementary school one of my teachers would play records (yes, vinyl records) of people singing multiplication tables to use. These records were played during our morning line-up times and other breaks during the day. Today, there are many more ways for children to learn and practice multiplication facts. Multiplication.com is one such example of that.

Applications for Education
On Multiplication.com students can choose from dozens of games to play to practice their multiplication skills. Students can play single-player and multi-player games. Before they play the games students can refresh their memories by working through the "fact" and "quiz" navigators that provide visual explanations of multiplication facts.
