Inbuilt 'raise a hand' and 'ask a question' features mean a student can confidentially ask for help and you can reply directly on their screen using annotation tools, including emoticons.

Monitoring & Control

Unio let’s you monitor all student screens in real time to check that they are on task and you can select and broadcast an individual’s screen to the whole class - or set up work groups, each with a shared whiteboard.
