Ultimate Timed Challenges
Fast-paced practice that builds fluency and exposes misconceptions. Pick a challenge, choose your questions and beat the clock.
How Ultimate Timed Challenges work
Pick a challenge, choose exactly which question types come up, and race the clock.
Play on any device with the on-screen numpad, or project a challenge to the board.
Two ways to use them
- 1
Independent practice
Students work on their own devices with instant feedback on every answer. At the end, a results breakdown shows what went wrong, and they can practise just their mistakes.
- 2
Whole class
Project a challenge to the board in Classroom mode and set the pace. Everyone answers on mini-whiteboards, so you see every response at once.
No challenges match
Try fewer words, or a different word for the same thing.
