In this version of the classic game, students are given different riddles to help them identify the correct clock.

Students can use mini whiteboards to solve the clues or the worksheet version on write-and-wipe sleeves to determine the answer. In the digital version, if the answer is clicked it will respond with either applause for correct answers or an explosion for incorrect answers.

These can be implemented as small group practices, a warm-up to mathematics lessons, skill revision and a conclusion activity to a lesson.
