Times in a 45-minute lesson

5 seconds goes 540 times into a 45-minute lesson, and half of it is gone at 0:03. At this length the bar is amber from the moment it starts and red for the last ten seconds: the whole countdown is the warning.

A little shorter, a little longer

The rest of the kit

• Name wheel

  Spin to pick a pupil. Nobody is picked twice until everyone has had a turn.

• Random groups

  Split the class into even groups in one click, by number of groups or by size.

• Stopwatch

  Start, lap, stop. Laps with splits, fastest and slowest marked.

• Focus timer

  Work and break rounds that run by themselves, 25 and 5 or your own.

• Random pickers

  Dice, a coin, a number out of a range, a letter — four draws on one screen.
