Challenge your understanding of place value in whole numbers up to 999. Receive a starting number, such as 328, and work towards turning it into a target number, such as 177, 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 your target! 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.
