Test your understanding of place value. Start with a two-digit whole number such as 57. 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 12, 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. This learning object is 1 in a series of 15 objects.
