B Block Methods B (Day 6) Mon., Sept. 30 — Solving Systems by Substitution and Graphing

Today: We talked about using substitution to solve systems.  There are times when graphing lacks accuracy, so it is important to know other methods.  It is also important to be bale to show that you know how and when to use substitution.

Homework: p. 384/ 5-15 odd, 17, 18, 27-31 odd.

Next Class:   We will work a little more with substitution, and then we will move on to elimination.

C Block Methods A (Day 6) Mon., Sept. 30 — Adding and subtracting Decimals and Fractions

Today: We went over the adding and subtracting from your homework.  You asked good questions, and I hope you were able to understand some things for the first time.  While we were working on that, others in the class went ahead and started on the investigation on p. 26.

Homework: p. 26/ 1-5.  If you want to finish the whole thing, you can.  We will work on the rest in class, but I want you to be able to ask questions about Activity 1 before we go on to Activity 2.

Next Class: We will work on Activity 2 and another part that I do not believe is in your book.  We will be displaying some of our work in class as well.

E Block Geometry (Day 5) Fri., Sep. 27 — Angle Relationships

Today: We learned about vertical angles, linear pairs, supplementary, and complementary angles.  We looked at their definitions, possible diagrams, and problems related to these types of angle relationships.  You had a little time at the end of class to begin your homework.

Homework: p. 70/ 8-10, 15-27, 36, 40; p. 79/ 18-32 even, 39.

Next Class: We will look at another piece to supplementary and complementary angles.  We will prepare for a quiz on the angle relationships.

B Block Methods B (Day 5) Fri., Sep. 27 — End of Grpahing Systems

Today: I discovered as I checked your homework, that some of you still aren’t graphing the systems of equations.  You must follow directions!  We worked on this for the remainder of the class.

Homework:   Some of you need to graph in your homework.  Others need to redo/finish p. 737/ 31, 32.

Next CLass:   we will go over the substitution method of solving systemsl

C Block Methods A (Day 4) Thu., Sep. 26 — Rules of Addition

Today: We worked hard to develop the rules of addition.  You guys saw how we took what you already know and understood and made it simpler: when you add numbers with the same sign, keep the sign.  When you add numbers with different signs, subtract the absolute values and keep the sign of the larger absolute value.

Homework:   You will now apply those rules to the following problems: p. 60/ 5-24.

Next Class:   We will go over the homework.  We will break into smaller groups for those who need to review adding decimals and fractions.  We will then look at subtraction and how it is similar to addition.

A Block Algebra 2 (Day 4) Thu., Sept. 26 — Direct Variation and Linear Models

Today: We were super fast and talked about many things after spending some time going over your homework.  We talked about the two equations given to you on p. 72: y=kx is the equation for a direct variation, and k=y/x is the equation for the constant of variation.  All of the problems in this section relate to these two facts. We also went over the idea of linear models: basically, you are using an equation to show what line matches the data or information given.  The examples we did in class, while giving the definitions on the outline, are all linear models.

Homework: At lest finish the first part before class tomorrow.  p. 74/ 2, 6, 7, 11, 12, 15-25 odd, 33, 35; p. 81/ 1, 2, 4, 7, 15-18, 22, 23, 27.

Next Class: We will go over the first part of the homework, but please check these before you come to class!  The faster we go over questions, the faster we can get to the fun new stuff!  We will be talking about the absolute value function/ graph and related functions and graphs.  I will also give you the review sheet to help you with the review for the test on Wednesday.

D Block Methods B (Day 4) Thu., Sep. 26 — Solving Systems of Equations Using Substitution

Today: We worked on understanding the homework problems that required us to graph and use substitution to solve s a systems of equations.  I like these problems, because they help us meet my goal of knowing which method to use when.  We also looked at some other cases of substitution.  Sometimes, we have to substitute an expression into an equation, and other times, we have to solve for a variable before we can substitute the expression.  Sometimes, the variable will subtract out and we will have a true statement, which means the solution is “all real numbers”; other times, the variable will subtract out, and we will have a false statement, which means the solution is “no solution.”

Homework: p. 384/ 11, 12, 14, 17, 21, 28, 35, 39.

Next Class: We will look at more systems and one more method of solving them.  We will also pull this all together with word problems.  You are going to have to begin deciding which method is the best to use and why.

B Block Methods B (day 3) Wed., Sept. 25 — The End of Graphing Systems of Equations… Sort of…

Today:  We had a substitute because of the cross-country meet.  You were able to work more on your worksheet and check your answers with the answer sheet and each other.  Then you worked on some problems in the textbook.  They are listed below.

Homework:   To finish whatever problems you did not complete from the class work assignment: p. 377/ 1-13 odd, 14, 15-23 odd, 24.  If you finished that page, you were supposed to re-look at p. 737/ 31 and 32.

Next Class: We will begin looking at other methods of solving systems, because we will see that graphing systems is not always effective.

E BLock Geometry (Day 3) Wed., Sept. 25 — Angle Relationships

Today:   We checked homework and answered questions.  After you spent some time going back through it, we worked on an activity where you had to meet certain requirements to build a diagram of Twizzlers.  I hope you enjoyed it.  It was fun watching you!

Homework:   We weren’t at a point to have anything to practice.

Next Class: We will continue defining the relationships between angles, so you can solve problems using those relationships.

C Block Methods A (Day 3) Wed., Sep. 25 – Review and Intro to Addition Properties

Today: We went over some problems that were assigned several days ago.  We checked them and answered questions.  Then, we began talking about the Identity Property of Addition (or Additive Identity) and the Inverse Property of Addition (or Additive Inverse).  Then, the bell rang, and I was very sad.

Homework: We weren’t at a place where you had anything to practice.

Next Class:   We will finish with the addition properties, look at rules of adding positive and negative numbers, and work with functions.
