Abstract
The device is comprised of a simulative roller coaster body, wherein a teacher can then place a card with an initial number in the middle of the body, between a card with a lower place value number and a card with a higher place value number. Then, a student can insert a wheeled roller coaster cart into at least one opening of the body, wherein the opening represents a digit of the initial number. The coaster will then fall down the channel and into a receiving area which contains a card with a lower place value number or a higher place value number. The presence of the coaster in either receiving area indicates whether the initial number should be rounded down to the lower place value number or up to the higher place value number.
