     TAKE THE TEST - Santa Clara County Office of Education


   Practice answering math questions in the format of the
   California High School Exit Examination (CAHSEE). On this
   site, students preparing to take this exam or others similar
   to it can:

     - answer a sample question
     - watch a math mentor solve the same problem
     - review a step-by-step solution

   Movies of English-speaking and Spanish-speaking math mentors,
   with transcripts for reading along in either language,
   require Quicktime.

   Six sections of math are covered:

     - Number Sense
     - Statistics, Data Analysis, Probability
     - Algebra and Functions
     - Measurement and Geometry
     - Algebra 1
     - Mathematical Reasoning




   Dr. Harry Bohan presents an activity that is designed to help
   the teacher promote a classroom feeling of, "Here is our
   task, to learn one-hundred multiplication facts. Let's set up
   a game plan to get this accomplished!"
