Welcome to SANDBOXmaths

This is a collection of short experimental video clips that all interrogate aspects of interesting mathematical ideas, results, concepts, conjectures, processes and observations.  All the videos use as their props materials that are readily available at home, at school or anywhere else.  This is because the clips wish to emphasise that mathematics is ubiquitous and can be done in any every-day context.

They are experimental in the sense that the videos attempt to interrogate a mathematical idea visually in an innovative manner that inspires further experimentation and interrogation.  All the videos are guided by the principle that they engage with the basic conceptual fundamentals and building blocks of a particular mathematical idea, process or concept.

This site is a sandbox because it should be a place where the notion of play, experimentation, getting your hands dirty and exploration are encouraged.

The guiding criteria for including video clips in the SANDBOX are:

  • is the video clip conceptually rich?
  • is the video mathematically compelling?
  • Does the video have a logical mathematical flow?
  • Does the video arouse curiosity?
  • Is the video visually convincing?
  • Is the video of high cinematic quality?
  • Does the video employ props purposefully?
  • Does the video employ text/non-text strategically?
  • Does the video use the stop-go technique well?

If you wish to submit a video that meets the above criteria, please submit it as soon as possible!  The idea is to build a global video platform that is of interest to all who are passionate about making mathematics visual.  Please ensure that you identify yourself either at the beginning or the end of the video clip.  Please also provide your institutional affiliation.  You may submit the video clip in any language provided you also submit an English version. 

Please submit your video clip to either:

The VITALmaths and VITALmathsLIC site consists of a databank of short and funky video clips that specifically interrogate the conceptual aspects of a mathematical idea, process or concept. Some of the video clips contain strategic dialogues to encourage appropriate mathematical talk and conversation.
SANDBOXmaths is a collection of more experimental video clips done by students in their mathematics teacher-training classes and researchers wishing to use specific video clips in their teaching and research.
The APPLETmaths site consists of a selection of GeoGebra applets that were developed by students and researchers for their research projects.
