    Learning

    What kids practise

    • Number sense: where numbers sit compared to each other.
    • Greater than and less than: every hint is a comparison.
    • Logical thinking: using clues to rule numbers out.
    • A first taste of computer science: the halving strategy is called binary search.

    Levels

    Which range to choose

    • 1 to 10 for ages 4 to 6, or for a first game.
    • 1 to 100 for ages 6 to 9, once they can count to 100.
    • 1 to 1,000 for older kids who want a challenge.

    Teachers

    Classroom ideas

    • Whole class game: put the game on the board and let the class vote on each guess. Ask why they chose it.
    • Number line: draw 1 to 100 and cross out numbers after each hint, just like the bar in the game.
    • Beat the teacher: can the class find the number in 7 guesses or fewer?
    • Pairs: use Duo mode so students hide numbers for each other.
