What it is

Olly looks after the town's clock tower. Children drag the long and short hands to match a time written in digits or words: o'clock, half past, quarter past and quarter to, then every five minutes and every minute. In the older track, they work out what the time will be later, or was earlier, and set the clock to match.

What children learn

Builds reading and setting analog clocks to the hour, half hour, quarter hour, five minutes and minute; the link between the minute hand and counting by fives; how the hour hand moves between numbers; and elapsed time forward and backward.

What it teaches

  • Tell time

How to play

Drag either hand around the clock face, or use the buttons to move the long hand and the short hand. Press Set when the clock is right. Keyboard: on the clock, the arrow keys move the long hand one step forward or back, Page Up and Page Down move the hour, Home goes to 12:00, and Enter sets the clock.

Plays with: Touch Mouse Keyboard Pen
