Make a Wall Mounted Worksheet.

Photocopy clock-faces and glue onto thin card. (Better still photocopy directly onto white card). Each child colours one clock to show the TO and PAST sides in different colours or patterns.
Laminate the clocks and cut them out.
Mount the hands using split pins.
Put 10 (or more) clocks up on the wall, each one numbered or lettered.
Each day one of the children sets the clocks and the others have a set period to write down the times in analogue or digital form, as you prefer. 
If your school can afford it each child can do 2 clocks, one to display and one to practice on.

NB If you photocopy onto paper and stick the sheets to card, be sure that the clocks are glued down all over (otherwise they come to pieces when you cut them out).
