Maths - Place value (three-digit numbers)

Test your understanding of place value with three-digit numbers. Click the to take you to the Wishball: Hundreds game. Start with a three-digit whole number such as 507. A spinner provides a randomly generated digit. Choose its place value and add it to (or subtract it from) your starting number. Work towards a given target number, say 539, using other digits. You can choose the final digit (the ‘Wishball’) to reach your target. Don’t overshoot (in addition) or undershoot (in subtraction) the target number! Try to achieve it within 20 turns, and in as few turns as possible.
