Layla Mehdi Pour, a young designer from Iran, created this adjustable “Sophie” clock. Another designer from Britain designed a colour clock. Rnd Lab for Progetti designed what at first glance looks like a random clock. These can be the basis for a whole unit on Time. What sort of clock can your students invent? Normally we think of an analogue clock as round. What other shapes can they be? Do all clocks need a number? Why? Why not? Do they all need hands? Why? Why not? You could select a group of students to research clocks online and share one interesting clock each day of your Time Unit.
