For helping kids tell the time. I use these around the outside of a standard clock to help them convert the hands into time. So the circles include :00, :05, :10, :15, :20 ... :55. Outside that at the 12, 15, 30 and 45 marks I have oçlock, quarter past etc. Found it to be a helpful tool.
Also available as a Microsoft Publisher file if you want to edit it.
