Published on

Join Mr. D for a mini-SAT Boot Camp. Mr. D will be showing the tips and techniques from his SAT Boot Camps. This workshop will focus on math, the language behind the questions and show participants what they really need to know before taking the math section of the SAT.
Find out the words on the test that give tips for how to solve the questions as well learning what formulas you really need to know before the taking the SAT. Students and parents alike will learn how to unravel the questions being asked into something they can solve quickly and easily. These techniques can be used for other testing situations and subject areas as well.

SAT Math: It's All About The Question

  1. 1. SAT  Math  –  Its  All  About  the  Ques2on!   OLD  -­‐  3  Tests   NEW  -­‐  2  Tests   TIME:   TIME:   25  Minutes  –  20  Ques.ons   25  Minutes  –  20  Ques.ons  (No  C)     25  Minutes  –  18  Ques.ons   55  Minutes  –  38  Ques.ons  (Calc)   20  Minutes  –  16  Ques.ons   CONTENT:   CONTENT:   Algebra  I   Geometry   Some  Algebra  II   Algebra  I   Geometry   Algebra  II   Trigonometry   Data  Analysis  (Prob  &  Stats)   What’s Different!
  2. 2. SAT  Math  –  Its  All  About  the  Ques2on!   OLD     Free  Response  and  Mul2ple   Choice  on  1  test  only.     ¼  point  deducted  for  wrong   answers  on  mul2ple  choice   ques2ons.   NEW     Free  Response  and  Mul2ple   Choice  on  both  (all)  tests.     No  points  deducted  for  wrong   answers.     What’s Different!
  3. 3.    3  Things  You  WANT  to                  Memorize  for  the  Math  SAT       SAT  Math  –  Its  All  About  the  Ques2on!  
  4. 4. 1.  The  Pythagorean  Theorem    a2  +  b2  =  c2     •  The  Pythagorean  Theorem  is  used  for   finding  the  length  of  the  hypotenuse  of  a   right  triangle.  While  that  is  great  and   useful,  it  can  be  used  for  much  more.       SAT  Math  –  Its  All  About  the  Ques2on!   a
  5. 5. The  Pythagorean  Theorem    a2  +  b2  =  c2     •  Instead  of  memorizing  the  distance  formula,   you  can  simply  use  the  Pythagorean  Theorem.     •  The  30-­‐60-­‐90  and  45-­‐45-­‐90  special  right   triangle  formulas  are  given  on  the  SAT,  the   Pythagorean  Theorem  can  be  used  in  place  of   those  too.     SAT  Math  –  Its  All  About  the  Ques2on!   a
  6. 6. 2.  Pythagorean  Triples   •  Here  are  the  two  Pythagorean  Triples   that  will  show  up  most  oWen  on  the  SAT:                          3-­‐4-­‐5        as  32  +  42  =  52                          5-­‐12-­‐13  as  52  +  122  =  132       SAT  Math  –  Its  All  About  the  Ques2on!   a
