Wishball challenge: thousandths

Learning Material  |  Interactive Lesson

Test your understanding of decimal place value. Start with a number such as 3.569 that includes thousandths. Spin a random digit, then choose its decimal place value. Decide whether to add or subtract the random digit from your target number. The starting number will be adjusted by the amount you choose. Work towards a given target number such as 7.832. 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.
