DRAFT-­‐This  is  a  work  in  progress.  MAG  wriAng  project  2012-­‐2013  

•  Many  games  use  a  tossed  coin  (heads    and  tails)  to  decide  who  will  go  first    eg.cricket  •  A  spinner  or  coin  toss  provides  an    equal  likelihood  of  choice  

                 Part  2  •  In  student  learning  journal  create  a  word  bank  

ü  record  the  word  probability  as  related  to  the  word  probable  

ü  likely  to  chance  something  will  happen  is  very  good  

ü  equally  likely  to  chance  is  just  as  good  that  either  of  two  things  will  happen  

•  Ask  students  to  come  up  with  their  own  definiAon  of  the  word  chance  

•  Use  a  spinner  and  model  a  graphic  representaAon  that  represents  this  meaning  

 •  ParAcipants  will  oOen  use  the  ‘best  of  three’  idea  to  

increase  the  likelihood  of  an  outcome-­‐discuss  whether  this  is  likely  to  result  in  a  fairer  result  •  In  maths  we  oOen  use  symbols-­‐introduce  students  to  

capital  P  as  the  maths  symbol  for  probability-­‐demonstrate  how  to  write  the  probability  of    

tossing  a  coin  and  having  it  land  on    heads  P(H)  

 

                 Part  3  •  Using  the  following  experiments  determine  the  outcome  

(possible  result)  e.g.  A  spinner  has  4  equal  sectors  coloured  yellow,  blue,  green  and  red.  What  is  the  probability  of  landing  on  purple  aOer  spinning  the  spinner?  It  is  impossible  to  land  on  purple  since  the  spinner  does  not  contain  this  colour.      

•  P  (purple)  =  0/4  =  0      

 •  Students  complete  in  learning  journal.  A  teacher  

chooses  a  student  at  random  from  a  class  of  30  girls.  What  is  the  probability  that  the  student  chosen  is  a  girl?  

•  A  glass  jar  contains  5  red,  3  blue,  and  2  green  jelly  beans.  If  a  jelly  bean  is  chosen  at  random  from  the  jar,  then  which  of  the  following  is  an  impossible  event?  

•  Choosing  a  red  jelly  bean  (A)  •  Choosing  a  blue  jelly  bean  (B)  •  Choosing  a  yellow  jelly  bean  (C)  •  None  of  these  (D)  

•  A  spinner  has  7  equal  sectors  numbered  1  to  7.  If  you  spin  the  spinner,  then  which  of  the  following  is  a  certain  event?  

•  Landing  on  a  number  less  than  7  (A)  •  Landing  on  a  number  less  than  8  (B)  •  Landing  on  a  number  greater  than  1  (C)  •  None  of  these  (D)

•  Sandy  a  family  friend  comes  to  visit  and  brings  a  drawing  of  Rachel  astride  a  unicorn  with  several  flying  pigs.  She  wishes  ‘things  like  that  did  happen  to  her,  but  believe    it  is  apparently  impossible’.  Sandy  tells  her  that  ‘nothing  that  you  imagine  is  totally  impossible,  it  might  be  unlikely’  

•  Discuss  the  role  of  imaginaAon  in  likely  and  unlikely  events  

•  Ask  students  to  write  a  ‘wish’  e.g.  ‘animals  could  speak’  on  a  strip  of  paper  and  place  it  in  one  of  two  envelopes  marked  likely  or  unlikely

 •  Discuss  the  choices  made  when  sorAng  the  wishes  •  What  might  vary  your  results?

•  Decide  on  range  of  the  scale  1-­‐5  

•  Listen/Look  for  word  clues  in  the  text.  eg.  havoc  or  disaster  

•  Use  a  dicAonary  to  look  for  synonyms  which  are  equivalent  in  meaning  to  the  chosen  word.  eg.  havoc  =  chaos,  confusion,  catastrophe,  disorder,  loss.    

•  ‘had  to  wear  a  bag  of  fish  and  chips  on  his  or  her  head  in  public  at  all  @mes’  

 

•  Ask  student  to  think  of  everyday  events  and  compare  them  to  the  imaginary  ones  in  the  story  eg.  ‘wear  bag  of  fish  and  chips’  with  ‘no  hat  no  play    rule’  

•  Use  a  Venn  diagram  to  sort  the  events  into  three  categories-­‐students  to  choose  and  jusAfy  choice  eg.  certain,  likely,  unlikely

students  to  brainstorm  ideas  about  the  likelihood  of  an  unlikely/likely  event  happening.  

•  Record  phrases  and  words  randomly  •  Ask  students  to  choose  a  spot  across  the  room  which  

represents    

             how  likely  they  feel  this  event  might  occur  (use  brainstorm  ideas)  •  Ask  students  to  explain  why  their  choice  is  reasonable,  

using  appropriate  language  e.g.  It  is  impossible  for  pigs  to  fly  as  they  don’t  have  wings.  

   Part  2  •  Retell  with  class  a  newspaper  report  from  USA  ‘ABC  News  

reported  that  a  300-­‐pound  pot-­‐bellied  pig  flew  on  a  US  Airways  flight  from  Philadelphia  to  Seafle  because  the  animal  was  deemed  a  therapeuAc  companion  pet.’  The  pig  was  recognised  by  the  airline  as  a  service  animal  that  the  owner  could  not  fly  without.  

•  Ask  students  if  this  would  change  where  they  are  standing?  •  ‘Pigs  might  fly’  is  a  figure  of  speech  that  uses  comparison  to  

such  an  extent  as  to  suggest  complete  impossibility.  Other  examples  are  'It  is  easier  for  a  camel  to  pass  through  the  eye  of  a  needle...'  and  'Make  a  mountain  out  of  a  molehill'.  

•  Lewis  Carroll  also  used  this  figure  of  speech  in  Alice's  Adventures  in  Wonderland,  "I've  a  right  to  think,"  said  Alice  sharply...  "Just  about  as  much  right,"  said  the  Duchess,  "as  pigs  have  to  fly.”

Background  

As  with  all  concept  formaAon,  it's  important  that  learners  meet  fundamental  ideas  informally,  well  in  advance  of  formal  teaching.  In  terms  of  probability  these  fundamental  ideas  are  those  of  fairness,  and  the  familarisaAon  of  the  language  of  chance.
