# Wishball: ultimate

TLF ID L870

Test your understanding of decimal place value with whole numbers or numbers that include tenths, hundredths or thousandths. Receive a starting number, such as 3569, 356.9, 35.69 or 3.569, and work towards turning it into a target number, such as 7832, 783.2, 78.32 or 7.832. Spin a random digit, choose its decimal place value and decide whether to add or subtract the random digit from your starting number. 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.
