Numberless Protractors

Print on overhead transparency sheets. Count up in 10° increments, and then estimate the last part.
Far less confusing than a regular protractor. Idea originally from Victorian Education Department's RIME materials.

Video Clips from YouTube


YouTube has many useful film clips to stimulate class discussion. Inviting students to find other numbers that work for a situation can be quite challenging.

Students can script and make their own film clips in response to the original stimulus...and post them up in YouTube.

Many educational jurisdictions block YouTube. Teachers have to play a 'filtering role' to identify and extract content useful for kids' learning.

As a workshop device, video clips are a great way to inject humour into a session you might be running with colleagues. What I have found useful is to use web-based tools like Zamzar ( to download QuickTime versions of content found on YouTube. It removes the latency in a teaching context when wanting to use the resource, by having the file reside on your hard drive.

Students' mobile phones and iPods represent a powerful medium to engage learners in school-related content. It is very easy to use Zamzar to convert YouTube content to a form for these devices. The bigger challenge is to convince colleagues that they have a place that is central to student learning!
