Warm-Up - methods of graphing lines in the form ax + by = c
  Try viewing MathTV for a refresher on how to graph lines of this form...  On the left side of the screen press Algebra, then Linear Equations in Two Variables (straight lines)  then choose the following problems:
   For an example of the slope-intercept method - choose problem #4 - Betsy as the tutor
   For an example of the intercepts method - choose #7 - Preston (English) or David (Spanish)
Launch/Explore
  Problems #1-2 on page 68 - be sure to READ all the information before and between problems
Summary
  Explain #1a and #2e to Ms. Totman
Homework - finish HW#12 from Friday, if necessary.  Otherwise, no homework

Wednesday, 2/22
I apologize for the lateness of this post.   I've been experiencing a combination of computer struggles and after-school meetings and have been unable to keep up as well as I'd like.


Continuing on with our exploration of "linear programming", we began writing inequalities (for our constraints) and equations (for our objective function) and using the graph to find the feasible points and those most worth our effort (along the border of the feasible region).
Explore:  p. 70 #3
Homework #13: p. 71 #4


Thursday, 2/23
Continue to work in groups on linear programming problems.
Today - Paizan's Pizza Problem (you can download by clicking on the link)
HW#14: p. 80 #1a-e (that's abcde)


Friday, 2/24
Wrap up Paizan's Pizza Problem -
  1.) the maximum or minimum objective function will occur at the corners of the feasible region.  Be sure to use these when searching for your best solution!
  2.) Don't trust your graph when looking for the corners... use a graphing calculator OR algebraic reasoning to find the intersection points!
Proficiency Check - Just Graphing
Make sure all homework #12-14 is complete and turned in by Monday.

Core 2--- Week of February 13-17

Monday, 2/13
Toolkit Entry - Quadratic Formula  (This powerpoint walks you through what we did, but not necessarily how we did it...)
Practice Using only Positive Values of a, b and c.
Homework #6 - Monday's Problems Only


Tuesday, 2/14
Today we went over common mistakes that are made while calculating the roots using the quadratic formula and then tried a few problems with multiple negative values...  These common errors include...

• When b is negative, you must put parenthesis around b² (on your calculator)
• When b is negative, don’t forget that  –b (as in:  –b/2a) will be positive.
• When dividing be sure to multiply the denominator of the fraction (2a) before you divide.
• Be sure to take the square root before you divide.    

Homework #6 - do Tuesday's problems tonight.


Wednesday, 2/15

Go over practice/review
Group Proof - together as a class
Set up #8 on page 308
Homework #11 - finish #8 - page 308 ... make sure each problem has marked diagrams and a complete 2-column proof including statements & reasons.


Thursday, 2/9
Definitions/Reasons for Proofs
 * REFLEXIVE PROPERTY:  anything equals itself... ex. a=a
 * DEFINITION OF MIDPOINT:  A midpoint of segment divides the segment into two equal pieces.  (If M is the midpoint of AB, then AM = MB.
 * CPCTC (aka: Corresponding Parts of Congruent Triangles are Congruent):  If two triangles are KNOWN to be congruent, then all the corresponding angles and sides are also conguent.
You will use these properties/definitions in the proofs today, so write them down and be ready to use them.


Station 1: We'll do this one during the review day.
Station 2: Complete the reasons for each step of the proof.  You will need to access the diagrams in your book!
Station 3: Find the error in reasoning for the students Shawna, Guillermo and Sandy.  You will need to access the diagrams in your book!


What's Up Update:
 - Final Assessment on Unit 4 - timeline
   Friday = Review Congruence and Similarity
   Monday = Assess on Congruence and Similarity
   Tuesday = Review Angles (parallel lines, angle pairs, angle algebra, angles in (and out) of polygons...)
   Wednesday = Assess on Angles

No homework tonight - all missing homeworks are due by Monday 2/13 so check on what you're missing!
