Learning Material  |  Interactive Lesson

Published on 2018 August 10th

Test your understanding of place value. Start with a three-digit whole number such as 507. A spinner provides a randomly generated digit. Choose its place value and add it to (or subtract it from) your starting number. Work towards a given target number, say 539, using other digits. You can choose the final digit (the ‘Wishball’) to reach your target. Don’t overshoot (in addition) or undershoot (in subtraction) the target number! Try to achieve it within 20 turns, and in as few turns as possible. This learning object is one in a series of 15 objects.
Students identify the place value of each digit in three-digit numbers.
Students add and subtract ones, tens and hundreds in three-digit numbers.
