Using it in class

Use the age range as a guide and review the questions for your class. Invite explanations and give thinking time. No formal curriculum alignment is claimed.

Give everyone time to think and discuss before one pupil acts at the board. The class explains and confirms together; hints and explanations stay until you move on.

Use an up-to-date browser on a computer connected to a whiteboard or shared display. Touch, mouse and keyboard; optional audio and reduced motion. No pupil accounts or personal devices.

Choose from 5 challenges up to the full activity. Discussion determines the duration: you set the pace.
