When a quick guess is needed to count something, rounding can make math faster and fun! Read about two friends who are helping at a school fair earn that measuring, adding, and subtracting is easier if the numbers are rounded to whole numbers first. The children figure out ways to use rounding to estimate the amount of money raised at the fair, too!
