11/30 wednesday

I wasn't in class today due to a meeting but here was my expectation that was passed on to you by the sub.


alg II - We looked at problems in the book on solving equations and writing equations from solutions that will help on the test.  We will review more tomorrow but hopefully you are doing some work on your own.


alg I -  Today you worked on the district task involving skateboards and then practiced more SOE's which you will turn in at the end of the week.

tuesday 11/29

Easy and fun day with the computers


alg II- we had a Kahoot and Desmos on polynomials.  Hw is to study for the test coming up.  Look at the review guide that is in an earlier post.  We also looked at #18 in section 4.9.



alg I -  Today we had Desmos after reviewing SOIs and looking at new techniques to solve SOEs.  No hw tonight.

Monday 11/28

alg II -     W went over the quartic trinomial that is factorable and found solutions through factors.  We also did our writing prompt for the unit to work on college and career readiness.  Finally, we took notes on 4.9 and completed #3,5, 7-9 on page  223



alg I -   We had a review of SOEs and then applied that work to system of inequalities.  Hw is the 5 problems on the board.

Alg II Review guide for polynomials

The test will have 9-10 problems.

3 solving polynomials; make sure you know how to use synthetic division and the quad formula to get all solutions including radical and imaginary.

1 on listing all possible rational roots given the equation


2 writing an equation given the solutions; if given the y-int. you may need to add a transformation to make sure it matches in the equation

1-2 volume problems; most likely like the one about making a box from a piece of cardboard

1 domain and range of a polynomial

1 graphing a polynomial based on a written description; knowing the vocab of transformations  + max, min, zeros, end behavior


These are all problems we have done in class several times so you most likely have them already but here are the pages in the text to look at if you have misplaced your work.

p. 184  #34, 33

p. 195 #33-35

P. 196 #55

P. 202  #9-13, 21, 22, 47

P. 209 #18-19

P. 218 #50, 52

Don't forget the post that has all the tutorial videos!

monday - wednesday 11/21/16 - 11/23/16

alg II -  Today we got our polynomials that we will build a rorschach drawing from.  See me immediately if you haven't gotten one yet.


alg I -  Below are the directions for our logo project.  It is due at the end of class on wednesday.

Linear Equations Logo Project

Directions:  You will create your personal logo that involves at least 8 lines and determine their equations.

Part A:  Steps

1.       Create a coordinate plane

2.       USING A PENCIL, draw your logo on the plane.

3.       Choose 8 lines that you will determine the equation.

·         2 must be positive slopes

·         2 must be negative slopes

·         2 must be a zero slope

·         2 must be an undefined slope

ON ANOTHER PIECE OF PAPER, you will write the equation to those lines in either slope-intercept or point-slope form. 

Part B: Steps.

1.       Choose 2 points on that line and write them down

2.       Find the slope between those 2 points

3.       Write the equation in either form.

*** Extra credit:  Write 3 systems of equations and name the point of intersection.

Grading:  30 points

Part A: 15 pts. -Logo: neatness (2), creativity (7), coordinate plane visible(2), effort (4)

Part B: 15 pts.  – math:  choosing correct points (3), finding correct slope (3), making correct equations (9)

Friday 11/18

alg II -   A really great performance task happened today!  People worked well in their partnerships and look to be close to being ready for the project and test.  If you have a moment this weekend, try to solve some polynomials, especially those with imaginary solutions.


alg I -  Today we worked on our mathematical writing in the Candy Bar writing prompt.  We reviewed what SOEs are and then solved a few unique one; congrats to those who got extra credit.  No hw this weekend.  Project next week.

wednesday 11/16

alg II -   We started with a diagnostic test on solving and writing equations/ p. 195 #51.  We finished with whiteboard problems which I found on p. 194 #10-12 and p. 202 #11-13, 31.  Hw is to practice solving polynom. using a graphing calc and synthetic division.



alg I -  "Which One Doesn't Belong"  wodb.com  #13, 21.  Then we finished in partners working on the final Line of Best Fit exercise.

tuesday 11/15

alg II -   If you missed today, what a shame!  Easy day with Kahoot and Desmos.  Hw is to make sure you are organized and prepared for Friday's perf task  Period 2 also did a little prep for the perf task.


alg I -   Another class that did a lot of Desmos today.  hope you liked it and learned something on lines and slope.
No hw but make sure you finish the line of best fit by Friday.

monday 11/14

alg II - started class by listing the possible rational roots of polynomials (hint:  they're the factors of the last number.  Next we worked on transforming polynomials functions using the whiteboards.  Lastly we started the hw in section 4.7 #3-30, 24, 30.


alg I -  warm up 12 to start class - graphing 2 equations.  We ended class with partners working on line of best fit due at end of class.

thursday 11/10

alg II -  started with another WODB (wodb.com), then drew the graph from #38 p. 217.  We compared using the graphing calc to the rational root theorem.  
We finished by doing several problems on p. 216-217 by working with a partner and whiteboard.


alg I -  p. 367 #12,  p,. 371  #4, then quiz.  We also turned in the work for the week so if you missed have it ready on Monday.

wednesday 11/9

alg II - hardest problem of the year on p. 218 #55.  Thanks to all those students who gave it a great effort!  We also did a few "which one doesn't belong" as well as review the hw.  We are coming to the end of the unit.  Please start thinking of where you need to improve.



alg I -  We also did a few "which one doesn't belong"  and then went to our groups to work on p. 367 #4 and then there were 4 problems on the board to work through.

tuesday 11/8

alg II -  Big ideas today.  We went back to writing equations from solutions but this time we had radical solutions and complex conjugates.  See p. 202 #21,24 if you missed.  We finished with a volume problem #55 on page 196.  Period 2 has hw which is 55-56 on page 196.  No hw for period 1.



alg I -  We reviewed the handout from Monday.  After we tried p. 366 #2 ad p. 351 #7.  We took notes on point slope vs slope intersect and hw was to graph the five problems on the board.

monday 11/7

alg II -   Most of you were here so you know this but what a good day!  Started with #37 and #52 on p. 217.  Period 1 went over quiz but period 2 will do so tomorrow.  Finished with a solving quad review in groups.  Hw p. 202 #9-12



alg I -   We did a Kahoot that reviewed slope.  It you missed it search on Kahoot under Donnalawrence and do "slope and graphing linear equations."  After that we worked in small groups doing a function handout.

friday 11/4

alg II -  If you missed today's quiz, you will make it up next week when you return.  We did a Kahoot to prepare for it as well as do #51-54 on p. 185.  Period 1 also wrote an equation using imaginary solutions.


alg I -   work was due today so turn it in on Monday if you missed.  We also reviewed line of best fit and worked on making a machine on a NBA model.  We finished with a whiteboard review.
