Standards and Benchmarks Covered in this Lesson

          I,1,4: Explore patterns (graphic numeric, etc.) characteristic of families of functions; explore structural patterns within systems of objects, operations or relations.

          IV,3,5: Apply their understanding of number relationships in solving problems.



Welcome! How was your weekend? What did you do? What happened at the student-faculty basketball game?


Anticipatory Set:

v    What were we doing last week?

v    How did we know what values to consider?

v    How can we find these values using a calculator?


Objective: After completing the investigation, the students will be able to graph the solution set to single and double inequalities given then inequalities.  Students will also find a generic method to finding these feasible regions of inequalities.



                  Students will begin investigation 4 of lesson 1 today.  I will guide them to a deeper understanding of how to graph inequalities on a Cartisian coordinated system given the inequalities and help them understand what these values mean.



v    Checkpoint Pg 79 Generic Method for graphing inequalities (review key concepts)

v    Assign homework: pg 79 OYO, Exercise Set 3 #9
