Special homework given to the fourth-grade students became a hot topic in recent days. A math teacher asked her students to count 100 million (grain) of rice. The teacher Miss Su told them to finish the special homework two days. Some parents and Internet users were (surprise) to hear that. They thought it was joke, and some said that it might take more than a year to finish it.
However, some said it was a good idea (give) such special homework. A parent said it would make students think. "First, I'll ask my daughter to count 100 or 1, 000 grains of rice. Then weigh (称重) (they). Next, multiply (乘) the number to reach 100 million. (final) we'll find out how big the number is," she said.
Later Miss Su (reply) that she hoped the students would think new ways to do the homework. "I don't want them to count in a (tradition) way. That would take too much time," she said.
