Learning objects Wishball challenge: thousandths


Test your understanding of decimal place value with numbers that include thousandths. Receive a starting number, such as 3.569, and work towards turning it into a target number, such as 7.832. 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.
