Wishball challenge: whole numbers

TLF ID L871

Test your understanding of decimal place value with whole numbers. Receive a starting number, such as 3786, and work towards turning it into a target number, 7664. 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 overshoot the target! You can use a 'Wishball' to help you reach the target number. Try to achieve the target with as few additions or subtractions as possible. This learning object is one in a series of ten objects.
