Challenge your understanding of place value in whole numbers up to 99. Receive a starting number, such as 86, and work towards turning it into a target number, such as 18, within 20 turns. Spin a random digit, choose its decimal place value and use the given operation (either addition or subtraction) on your starting number. Be careful not to 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.
