One of the most popular posts on this blog is the one on online whiteboards which has been updated recently. Using Screenr recently I was reminded how well it works. It is also possible to easily upload a Screenr screencast to YouTube.
This was part of some feedback on a homework task (Tethered Goat – see nrich version here).
The video has been uploaded to our class wiki (I use Wikispaces).

The wiki page includes advice on the features of a great solution, some questions for reflection and some images of student work.
Hi, This is awesome!!! As a retired math teacher & Technology Director for 33 years, I’m constantly blown away at the wonderful tools that educators and students have at their disposal.
…and I thought I was innovative, when I began allowing students to use calculators in class back in the ’70s…;-)
This is a fabulous blog and resource for teachers. I’ll be sure to mention it and link to it from my blog. Thanks…Lee
Thank you Lee. I still remember my first calculator – a Sinclair woth reverse Polish notation!
