Challenge your understanding of place value in whole numbers. Either only add or only subtract numbers in ones or tens to reach a target number. For example, you must subtract. Receive a starting number such as 86. Spin the number 5 and decide whether to subtract 5 or 50 to reach your target number of 18 within 20 turns. Don’t undershoot the target number! Use the ‘Wishball’ to select your final digit. Try to achieve the target in as few turns as possible. This learning object is one of a series of 15 objects.
