I Have a Dream!

The third Monday of January is the holiday commemorating the birthday of Martin Luther King, Jr. The first time Martin Luther King Jr. Day was celebrated was in 1986. Try to solve these problems without using a calendar!

Eight is Enough!

In 1998, Nkem Chukwu gave birth to the first set of surviving octuplets.  The eight babies weighed from 11.3 ounces to 28.6 ounces at birth.  Leonard Weisman, the Texas Children’s Hospital’s chief of neonatal services, said it was imperative they gain lots of weight before they go home.  “For instance, the 500-gram babies are going to have to quadruple their weight [to reach a healthy level],” he said.  How many ounces will the heaviest baby have to gain to reach a healthy level?

American Idol Mania!

Season 17 of American Idol ended earlier this year. At the end of the season finale, each of the three judges was asked to share his/her opinion about who should win the contest; Laine or Alejandro.  Each of the three judges responded and audiences around the country basically heard “Laine,” “Laine,” “Laine.”  If each judge answered either “Laine” or “Alejandro,” how many additional ways could the judges’ responses have been heard? 

Getting Ready for School

It’s probably a little strange to think that some students started school last week, some have another couple of weeks of summer vacation and still others are just continuing with their year-round school schedule!  The date of the beginning of the school year has been a topic of debate throughout the last decade (and even before) in many areas across the United States.  But the trend is definitely leaning towards starting school earlier rather than later.  Basically, in the last 10 years, the percent of public schools going back to school before Labor Day has increased by 63%
