A Block Algebra 2 (Day 4) Thu., Oct. 31 — Study for Test on Systems

Today: We checked answers to homework and began our review for the chapter test.  You all got study stars and we talked about other things you can do to help yourself be ready for the test.

Homework: Study.
Chapter Test: p. 161/ vocab 1-5, 6, 8, 12-14, 18, 19, 23, 32, 34, 37, 38, 42.
Chapter Test: p. 164/ Choose one problem of each type (optional).
Extra Practice:  p. 840-841 (optional) great word problem practice back here!

Next Class: We will continue to study for the test.  You will get your quizzes back, your worksheets.  We will go over an example of a three-Dimensional word problem

D Block Methods B (Day 4) Thu., Oct. 31 — Boss/ Secretary Inequality Practice

Today:   We quickly went over homework problems and reviewed the rules of dividing and multiplying by negatives.  Then, you practiced solving inequalities with the Boss/ Secretary activity.

Homework: Practice for the quiz on 4.1-4.3.

Next Class: We will continue with the Boss/Secretary activity and take a short quiz.

B Block Methods B (Day 3) Wed., Oct. 30 — Presentations and a Multiplying/ Dividing Blitz

Today: We finally finished presentations and learned that we are not very good listeners.  Some of you did well listening, and almost all of you did well presenting!  Good work!  At the very end of class, we reviewed the rules for multiplying and Dividing by negatives.  It was really fast, so it might be helpful to look at examples in your textbook or come work with me after school!

Homework: p. 209/ 39-41, 60-64; p. 215/ 1-4, 17-20.  29 and 30 can be done if you need a challenge.

Next Class: We will practice with multiplication and division.  There will be a quiz soon!

E Block Geometry (Day 3) Wed., Oct. 30 — Proving Lines are Parallel

Today: We talked about how to use the converses of our postulate and theorems to prove that lines are parallel.  You guys did an alright job of participating in class.  we need to work on bringing textbooks and staying awake!

Homework: Complete the worksheet given to you in class.  On 1-6, you need to justify our first step (words that prove you can set up the equation), and you might want to practice justifying every step, since that is what you will be required to do on the highest levels of the test.

Next Class: We will continue working with parallel lines, using Brandon’s postulate, along with another, to add to how we can prove that lien are parallel.

C Block Methods A (Day 3) Wed., Oct. 30 — Presenting Exponents … Still

Today:   We should have finished presenting the exponent problems, but I talked to long at the beginning of class.  Oh well.  Everyone has ha d a chance to speak in front of the class about exponents and use the right language to talk about them.  That is important to me.

Homework: p. 433/ 46-62.  remember your rules of exponents

  • If the exponent is zero, replace the base and exponent with a 1.
  • If the exponent is negative and in the numerator, move it down; if it is negative and in the denominator, move it up.

Next Class: We will finally finish the presentations and finish the rules for multiplying exponents.  We will also work with dividing them.  You will get your tests back and develop a plan for making up what you missed.

A Block Algebra 2 (Day 2) Tue., Oct. 29 — Systems with Thre variables Practice

Today: We had practice time with the systems of equations.  I challenged you to be detectives.  Instead of doing the work all over again, find your mistake.  It will be painful, but the benefits are tremendous.

Homework: This will differ somewhat for some that I talked to, but you need to correct your homework and do the odd problems on the worksheet plus #10.  (Unless I told you otherwise.)

Next Class: I kept wondering why Susan was asking me about the test.  We are at the end of the chapter!  Duh.  My bad!  I think we should have a quiz on the 3-D part, review, and then test.  So that means you are sort of beginning your review now.  We will have a formative quiz on 3-D on Friday, which means we can review, discuss and be ready for a test by next Friday.

We might need to move forward with something else at that point, too.  You will have an investigation involving systems of inequalities that you will be required to do for this unit, so we might start that on Thursday.  You will have time to work on it…

D Block Geometry (Day 2) Tue., Oct. 29 — Solving Inequalities that are Verbal and that use multiplication

Today:   We spent some more time with simpler inequalities that required you to analyze the words used.  You will see these in more challenging word problems, so it’s good that you did so well with them today.  You also put some problems up that used multiplication.  We realized that when we multiply both sides by negative numbers we change the inequality symbol — not when it’s just a negative on one side.

Homework: p. 209/ 60-64.  Look at them again.  p. 215/ 5-8.  Use multiplication again.

Next Class: We will continue our crazy learning of this — back and forth, back and forth, challenging things, easy tings, challenging things, easy things.  There will probably be a few more problems on the board and a worksheet to prepare for an upcoming quiz.

E Block Geometry (Day 2) Tue., Oct. 29 — Parallel Lines and Angles, Proving Lines are Parallel

Today:  We took a quiz on using parallel lines.  We also practiced more with explaining why some angles are congruent when we know lines are parallel.  We ended class while trying to figure out the difference between the Corresponding Angles Postulate on p. 128 and the Corresponding Angles Converse on p. 138.

Homework: None.

Next Class: We will work more with parallel lines and proving lines are parallel.

B Block Methods B (Day 2) Tue., Oct. 29 — Solving Inequalities

Today: You were assigned an inequality from the class work and homework assignments you were supposed to complete.  You practiced being good listeners and asking good questions.  You are going to have to learn to focus and listen even when you don’t want to.  You are going to work hard to talk and work within your group only.

Homework: p.  209/ 39-41.  Follow all directions.

Next Class: We will finish the presentations, making sure all of you know how to speak English about inequalities.  Once we finish, we will continue with our study of division and more challenging inequalities.

C Block Methods A (Day 1) Mon., Oct. 28 — Rules of Exponents: Zero and Negative Powers

Today:   We continued our study of zero and negative exponents with presentations of problems that require the use of these rules.  Eric was grilled for his presentation, but he held up well.  Others got a way with little effort.  Let’s work on being a better audience, even when it’s hard.  We are more than half way through the presentations, so be ready to be a good audience again!

Homework: If you have lots of corrections to make on p. 433/ 30-44, do that only.  If you were somewhat successful with this first assignment, you need to work on p. 433/ 46-62.

Next Class: I will see what assignment you chose to do.  We will finish presenting our problems, and we will move on to new rules of exponents.
