Challenge your understanding of place value in whole numbers. Either only add or only subtract numbers in ones, tens or hundreds to reach a target number. For example, you must subtract. Receive a starting number of 328. Spin the number 5 and decide whether to subtract 5, 50 or 500 to reach your target number of 177 within 20 turns. Don’t undershoot the target number! Use the ‘Wishball’ to select your final digit. Try to reach the target in as few turns as possible. This learning object is one in a series of 15 objects.
