About This Product
Measuring a long distance with a ruler means many repeated placements, whereas a wheel only needs its turns counted. Because one revolution of this wheel equals half a metre, students can work out the distance from the number of turns, and the non-slip rubber tyre helps the wheel roll steadily for a more reliable reading.
