Advice needed - protractors

[trinity0097]

I teach a child who has very limited use of one hand, what do your children use/do when doing geometry work and need to use a protractor. Measuring an existing angle should be OK, but drawing out one would normally need one hand to steady the protractor and one to mark the point. Any suggestions as to adapted geometry sets - google is not being very helpful!

Anti-slip protractor?

RNIB ones?

digital angle rule any good?

Or silver line protactor.

The last two links didn't work?

Oh, sorry lets try again.

silverline protractor.

digital protractor

Like the idea of the digital one, but I don't want to go down the route of something that wouldn't be allowed in exams further down the line!

They often make allowances if an application is made. It only gives a digital reading of the angle cannot be used to aid in any other way I would think it would be allowed, print out a pic and ask for advice.
