Have you ever thought about one question:why do we need to learn math?
It is an interesting question.Kids around the world have been asking it for years.For US students,they may get the answer from a new exhibition called"Math Alive!"(1)47 activities are designed to teach kids how math is used in everyday life.For example,at one exhibition station,visitors can test that a person's arm span(臂展) equals their height.At another station,visitors can control the robot with the help of math skills.
The exhibition will visit 15 US and international cities in the next five years.Organizers say they want more kids to learn why math is important in daily life.Think of simple things,like clocks.They tell time,but only if you know how to read them.That means using math.How much longer until school ends?How long did you sleep last night?That's all math,too.
(2)When you go ,you also do lots of .How much change would you get if you paid for a 25.99-yuan sweater with two twenties?How would you calculate a 30% discount?Even when you're not doing math,it's all around you.The computer you use to surf the Internet is a machine to do binary(二進(jìn)制) math very fast.
So enjoy math,not for exams,but for the wonderful world it helps to build.
