vMiniWB was started in 2017 for use in classrooms, but elevated in priority when its virtual/remote potential was realised during the pandemic. Post pandemic it has become the useful classroom tool originally envisaged. I hope you'll find it a useful tool whether you are in the classroom or on-line.
vMiniWB.com has been written by Marcus Butler, a Classroom Mathematics Teacher who previously worked in IT. See mrbutler.org.uk for some of his other Apps and resources.
