=Monday, September 26th, 2011= We began class by taking a look at IW #8 together and sketched some parent function graphs to memorize on the board. After some graphisthenics (go ahead, Google it!) and another look at the transformations sheet, we practiced function transformation graphing with a game (submit team answers to each graph here).

__IW #9__:
 * p.89/21-39 all
 * QUIZ on IW #1-#8 next class

=Thursday, September 22nd, 2011= We began by solving a challenging equation and learning how technology like wolframalpha.com or the Solver on the calculator can make solving any equation a snap. At this point, everyone should have completed this brief student information sheet. We corrected the quiz, noting the need for efficient solutions, including those that made use of the calculator and/or Geogebra as well as those that do not. We discussed IW #7 and the and mentioned the idea of a parent function.

__IW #8__:
 * [[file:math-ob/U1 IW #8.pdf|This sheet]]

=Tuesday, September 20th, 2011= We began by answering this question and completing this brief student information sheet. We then took the quiz. We took brief notes on function composition and then checked the transformations sheet using. We discussed how in general 2f(x) ≠ f(2x) and how points can be used to identify transformations.

 * p. 66/1, 9, 15, 23, 31, 55, 69

=Friday, September 16th, 2011= We started class by using Geogebra to explore the parabola sheet problems. We then transitioned to exploring transformations of functions using this Geogebra sketch:. A summary of the transformation notes.

__IW #6__:
 * Transformation sheet
 * QUIZ on IW #1-#5 next class

=Wednesday, September 14th, 2011= We began by checking the common algebra errors sheet in pairs. We then took a brief look at the proof and result from p. 45/84. We corrected the quiz and ended class with an investigation into what makes a parabola a parabola. .

__IW #5__:
 * Parabola sheet

=Monday, September 12th, 2011= We began class by finishing the final IW #2 questions, thereby revising the good calculator usage. We then took the quiz and ended by discussing IW #3 using Geogebra.

__IW #4__:
 * p. 45/84
 * Common Algebra Errors sheet

=Thursday, September 8th, 2011= We began class by finding the domain and range of an interesting function algebraically and graphically. We discussed how to use the equation-graph-table triumverate on the graphing calculator and then looked at some questions from IW #2. We learned how to use the table to get an appropriate viewing window and how to use Calc-Intersect. We then took some notes on linear functions using a problem on Geogebra, including slope intercept form, standard form, point-slope form, horizontal and vertical lines, parallel/perpendicular slope relationship, and linear inequalities.

__IW #3__:
 * QUIZ next class on IW #1 and IW #2.
 * Look over IW #1 and IW #2 and make sure they are checked and corrected. If there are any errors remaining, stop by MDS to fix them up! You will be able to use them on the quiz next class.
 * p. 42/5, 11, 19, 27, 31, 43, 45, 65, 83

=Tuesday, September 6th, 2011= We began class with a function matching game to talk about the graph-equation-table connection. This led to a discussion of domain and range. We explored three interesting functions using [|this applet] and our graphing calculators. We discussed the responsibility and independent work rubrics and went over IW #1, answering all questions in preparation for the quiz next Friday.

__IW #2__:
 * p. 30/21, 39, 45, 50, 51, 52, 53, 54, 58, 59, 60

=Wednesday, August 31st, 2011= We began class with some introductions and a discussion of the course methodology, including what Pre-AP Calculus is all about, expectations for class, the importance of independent work, how to get help, and more. We then discussed functions by examining [|this applet]. The importance of viewing functions numerically and graphically is the reason each of us must have a graphics calculator for this class- and the future.
