countdown

the class was cleaning up the floor while i counted down. the rule is once i reach 0, they should all be in their seats. i was nearing 0 and they were still cleaning so i started counting by fractions, "one...three fourths...one half...one fourth..." allan joined in, but he doesn't quite have the firmest grasp on fractions yet: "one fourth...one third....one tooth...miss a, what comes after one tooth?"
