TLF ID L8458
Test your understanding of place value in two-digit numbers. 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, for example 12, using other digits. You can choose the final digit (the ‘Wishball’) to reach your target. Be careful not to 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 one in a series of 15 objects.
