We reviewed for the test today. Answers to previous quizzes are on the
web site. Answers to WS 2-16 are also in answers folder. Answers to
Review #3 are also on web site. I don't expect students to complete
all problems on that worksheet. However, if they need more practice
they have more than enough problems that they can practice. We start
new statistics unit on Friday.
Day 26 : 16 Sep 2008
Short day because of early release. We reviewed for test. We spent
most of the class period talking about the distance and midpoint
formulas.
Day 25 : 15 Sep 2008
Test on Thursday. Use the Pythagorean Theorem to derive the formula
for the distance between any two points in the coordinate plane. Also
derived the midpoint formula for two points in the plane. Homework WS
2-14 and p. 196 #1-23 odd. Tuesday and Wednesday will be test review
days and Thursday is our Unit 2 test.
Day 17 : 03 Sep 2008
HW quiz tomorrow. We reviewed all outstanding homework today, so you
should be ready for the quiz. We introduced two new triangle
inequality theorems. Quiz on Friday will include sequences. If you're
still not understanding sequences, come see me on Thu. or
Fri. morning. HW p. 287 #4-9, 13-27 (from textbook).
Day 16 : 02 Sep 2008
We reviewed both forms of sequences: recursive and closed form. We
practice writing both types given a sequence. We learned about the
external angle theorem. We will have a quiz (and test makeup for
sequences on Friday). HW: WS More Sequences Practice; WS 2-5 (front
only) on using the external angle theorem.
Day 15 : 29 Aug 2008
In groups we investigated the triangle congruence postulates further.
HW: WS 2-4.
Day 14 : 28 Aug 2008
Tests were returned. New unit on polygons started today. We reviewed
the meaning of congruent polygons. We learned 5 theorems that allow us
to prove two triangles congruent if given information about 3 pairs of
sides or angles: SSS, SAS, ASA, AAS, HL. Key definition is included
side or angle. This help distinguish between ASA and AAS. HL only
applied to right triangles. SSA doesn't work! HW: WS 2-3 on congruent
triangles
Day 13 : 27 Aug 2008
Test.
Day 11 : 25 Aug 2008
Test Wednesday (8/27). Lecture over Sequences and lecture on function
transformations. HW: Section 3.13 in textbook (online) p. 185, do
problems on p. 187 #1-20 skip #12 Also do Honors Algebra 2 worksheet
1-11 on simple transformations skip #7-9 and #16-18.
Day 10 : 22 Aug 2008
Quiz #2. WS 1-13 on sequences as functions assigned to work on your
own. I was out sick.
Day 9 : 21 Aug 2008
Spent most of class going over average rate of change homework (WS
1-12) and characteristics of functions homework (WS 1-11). Also went
over last three parent functions: rational, cubic, and square root.
Day 8 : 20 Aug 2008
Homework quiz. Spent a lot of time going over WS 1-9 and WS 1-10. More
average rate of change especially how to calculate it for non-linear
functions. Learned how to use calculator with function notation to
fill out a table for d(x) = 5x^2. I didn't show you how to use the
table function on the calculator to generate the whole table at
one. HW WS 1-11 on describing the characteristics of functions and WS
1-12 on calculating the rate of change.
Day 7 : 19 Aug 2008
Warm Up: Finding the slope of a line given the graph. Homework
quiz. Went over WS 1-8. Introduced average rate of change which for
linear functions is the same things as the slope of the line. In class
and homework assignment &ndash WS 1-9 and WS 1-10.
Day 6 : 18 Aug 2008
Warm Up: Interval notation practice. Lecture: Conditional statements,
hypothesis (p), conclusion (q), (if p then q), converse (if q then p),
negation (~), inverse (if ~p then ~q), contrapositive (if ~q then
~p), and logically equivalent (conditional statements and
contrapositive statements are logically equivalent &ndash meaning if
one is true the other also must be true. Lecture: characteristics of
absolute value and quadratic functions. HW: WS 1-8 introducing idea of
average rate of change; WS 4-3, p. 204 more conditional statements
practice. Expect a homework quiz tomorrow.
Day 5 : 15 Aug 2008
We took our first quiz and went over it afterward. The quizzes were
could have been better. We need a lot of work on identifying the
characteristics of functions (domain, range, increasing/decreasing,
local minimums and maximums, end behavior, roots, x and y intercepts,
etc.). WS 1-6 was assigned where you will learn about logical
equivalence (standard G2) and also about another important parent
function &ndash the absolute value function. Summary: Quiz #1, WS 1-6
HW: WS 1-6 (finish) Review your answers for WS 1-1, 1-2, 1-3, 1-4
(#1-3). Expect HW quiz on Monday or Tuesday or both.
Day 4 : 14 Aug 2008
We worked through #1-2 on WS 1-4, which was your homework from the
night before. You will have a quiz tomorrow. The list of topics on the
quiz is here. Homework
for tonight is to finish #3 on WS 1-4. The main theme so far is
functions: how they are used, how they are represented (tables,
graphs, rules (equations), function notation), and their
characteristics (domain, range, increasing/decreasing, local minimums
and maximums, end behavior, roots, x and y intercepts, etc.).
Day 1 : 11 Aug 2008
In class, we worked through #1 on WS 1-1, which
was a reminder of how functions can be represented using tables and
graphs. We discussed briefly the difference between continuous and
discrete variables, which allows you to decide whether or not you
should connect data points with line. Homework was to work on #2-4 from
WS 1-1. I suggested that you spend 45 minutes on the homework
assignment and do as much as possible &ndash only applies if you
aren't watching the Olympics or anything else while you are doing the
homework.
