SUMMER WORK FOR RISING ADVANCED ALGEBRA AND GEOMETRY STUDENTS Barrie Prep 2016 Solve part I in June, part II in July, part III in August. The idea of the review is to do little work (each of these 3 packets should take about 3 – 4 hours of work), but spread in time so it refreshes your memory every now and then and keeps alive the knowledge you acquired during the year. Of course, you can do everything in August, but by then your memory will be stale beyond the rejuvenating power of this packet. Or you can do it all now, but by late August, when classes begin, you will have trouble to retrieve this knowledge from the dungeons of your memory. If you want to invest your time poorly, go ahead. If you solved a problem and the solution can be checked using your calculator, by all means do it. Moreover, consider the checkingwithyourcalculator thing part of the problem. Work hard at resolving discrepancies. Not so hard that it mars your vacation (intelligence includes having a sense of proportion). If a problem or group thereof is still driving you crazy, you will find help at [email protected]. USE IT! Be explicit about what you did, what you got, and/or what you find puzzling. A couple of sentences. You may include a scan in your email. Help may delay a day or two.

STUDENTS  

 

 

 

 

 

Barrie  Prep  2016  

●   Solve  part  I  in  June,  part  II  in  July,  part  III  in  August.      The  idea  of  the  review  is  to  do  little  work  (each  of  these  3  packets  should  take  about  3  –  4  hours  of  work),  but  spread  in  time  so  it  refreshes  your  memory  every  now  and  then  and  keeps  alive  the  knowledge  you  acquired  during  the  year.  Of  course,  you  can  do  everything  in  August,  but  by  then  your  memory  will  be  stale  beyond  the  rejuvenating  power  of  this  packet.  Or  you  can  do  it  all  now,  but  by  late  August,  when  classes  begin,  you  will  have  trouble  to  retrieve  this  knowledge  from  the  dungeons  of  your  memory.  If  you  want  to  invest  your  time  poorly,  go  ahead.  

●   If  you  solved  a  problem  and  the  solution  can  be  checked  using  your  calculator,  by  all  means  do  it.  Moreover,  consider  the  checking-­‐with-­‐your-­‐calculator  thing  part  of  the  problem.    

●   Work  hard  at  resolving  discrepancies.  Not  so  hard  that  it  mars  your  vacation  (intelligence  includes  having  a  sense  of  proportion).  

 ●   If  a  problem  or  group  thereof  is  still  driving  you  crazy,  you  will  find  help  at  [email protected].  

USE  IT!  Be  explicit  about  what  you  did,  what  you  got,  and/or  what  you  find  puzzling.  A  couple  of  sentences.  You  may  include  a  scan  in  your  email.  Help  may  delay  a  day  or  two.

●   Turn  in  the  packet  with  your  solutions  the  first  day  of  classes.  It  will  be  a  conversation  piece  the  first  week  of  class.    

●   Starred  questions  deal  with  material  not  covered  by  all  the  students    

●   Enjoy  your  vacation!
