MATH IN THE NEWS – MATH VOCAB
• WHAT DO YOU KNOW ABOUT THE EBOLA VIRUS?
• IN JUST A MINUTE WE ARE GOING TO HEAR TO A 3 MINUTE NEWS CLIP AND LISTEN FOR SOME MATH/SCIENCE WORDS.
DON’T PANIC – BE INFORMEDDon’t Panic!Ebola is spreading rapidly in parts of Africa because of poverty, poor sanitation, lack of access to medical care, and people’s superstition and lack of knowledge about how the disease spreads Ebola is not spread through
casual contact, but most commonly through direct contact with the blood of an actively sick person or An infected corpse

WHEN YOU HEAR THE STORY, WRITE DOWN WHAT YOU THINK THE FOLLOWING WORDS MEAN
ExponentialA number that keeps doubling. On a graph it can grow slowly at first then form a steep curve.
Computer modelA computer program that is designed to show what might or what did happen in a situation.

THERE IS A STORY ABOUT A WISE MAN WHO WON A REWARD FROM A KING AND ONLY ASKED FOR GRAINS
OF RICE ON A CHESS BOARD. HE ASKED FOR ONE GRAIN ON THE FIRST SQUARE, 2 ON THE SECOND, 4 ON THE THIRD, AND SO ON WITH EACH AMOUNT OF RICE DOUBLING IN THE NEXT SQUARE. BEFORE THE CHESS BOARD WAS EVEN FULL THE AMOUNT OF RICE COST MORE THAN THE KING HAD IN HIS ENTIRE TREASURY.
