Monday – Lesson 7.3 Solving Advanced Systems by Substitution: Students learned how to solve advanced systems of linear equations by the substitution & how to solve word problems using a system of equations & the substitution method.

Tuesday – Lesson 7.4 Solving Systems by Elimination: After teaching students the more difficult ways to solve systems of linear equations, we worked on learning how to solve systems by the elimination method. Often, this method is easier for students. Actually, the class found it unbelievable that I was holding out on them in that I did not teach them this method until after the others. :) Students also learned how to solve word problems using a system of equations & the elimination method.

Wednesday – Chapter 6 Careers in Math ~ Computer Programmer/Software Engineer & Chapter 7 Sequences ~ Limit of a Sequence:Students learned how to distinguish between the responsibilities of computer programmers & software engineers as well as to recognize the necessity of a strong mathematical foundation for computer science careers. We spent time looking at some of the specific math courses required in college for these areas. We ended the hour learning about limits on converging sequences, a main concept of calculus.

Thursday – Reviewed Chapters 1-2.

Friday – Reviewed Chapters 3-4.

Have a great weekend!

Hello!

Because good learning starts with questions, not answers, we are are really working hard in Algebra I to develop inquisitive minds. For this reason, students have been required to complete their online assignments with submitting an “I wonder....” question. I have been extremely pleased with the excellent questions I have been receiving. As I am seeking to develop a rigorous, inquiry-based classroom, I have noticed that these student-generated questions are driving instruction and encouraging engagement. It has been very helpful for me to allow these students to ask questions to show me what that they are thinking and to help me to know how to best answer the questions during the instruction time (because the videos they watch are a preview to the next day’s lesson, they should have questions!) I am excited as this will continue to keep students engaged, will help students develop their curiosity, and will also help students forge paths to new thinking (which will lead to learning!) It has been a good week!

Monday – Math in History - Rene Descartes, Sequences - Converging & Diverging: Students learned to identify Descartes as the developer of the Cartesian coordinate plane and to recognize the danger of exalting human reasoning above scriptural revelation. Students also learned how to state the finite number that a converging sequence gets closer to as n gets larger and how to classify sequences as converging or diverging.

Tuesday – Lesson 7.1 Graphing Systems of Equations: Students learned how to solve systems of linear equations by the graphing method (something they also learned Wednesday on the graphing calculator), and how to recognize three possible types of solutions for a system of two linear equations.

Wednesday – Chapter 7 Technology Corner: Students learned how to graph systems of linear equations on their graphing calculators.

Thursday – Lesson 7.2a Solving Simple Systems by Substitution: Students learned how to solve simple systems of linear equations by the substitution method, and how to solve word problems involving two unknowns using a system of equations and the substitution method.

Friday - Lesson 7.2b Solving Simple Systems by Substitution: Students reviewed how to solve simple systems of linear equations by the substitution method, and how to solve word problems involving two unknowns using a system of equations and the substitution method.

Part of this course is teaching students how & when to properly use the calculator. I have emphasized with the students that this tool will not be used to perform basic math operations.

As you know, students can expect homework every evening except Wednesdays. However, due to the day off on Monday, there is no homework today (Friday). Enjoy the weekend!

Hello!

Here is an update on Algebra I this week:

Monday - Lesson 1.5 Multiplying Rational Numbers: Students worked on multiplying signed integers & rational numbers. They also identified & applied the properties of multiplication.

Tuesday - Lesson 1.6 Dividing Rational Numbers: Students divided signed integers & rational numbers, demonstrated that division by 0 is undefined, & applied the properties of real numbers.

Wednesday - p. 40 Technology Corner: Using a few online tutorials from hotmath.com as well as the Technology Corner section in the textbook, students were introduced to a few of the basic functions on their TI graphing calculators.

Thursday - Lesson 1.7 Exponents: Students learned how to simplify and evaluate expressions with integral exponents using the properties of exponents.

Friday - Lesson 1.8 Order of Operations: Students can state the order of operations as well as evaluate numerical expressions using the order of operations.

Students are continuing daily to build speed with rapid calculations. On Wednesday, students also had a chance to play 24-game. There were a few quiz and homework grades this week. Check Renweb for those results. Many of the students have been doing very well keeping up with both the written & online homework assignments. Please help by asking your student daily if their work is ready for class. Thanks!

Reminder: Test #1 TUESDAY!

Hello!

We are off to a wonderful start in Algebra I. Students are doing very well keeping up with both their written & online homework. Here is an overview of our week:

Monday - Lesson 1.1: Sets of Numbers. Students worked on identifying sets & subsets as well as their union & intersection. Students reviewed Venn diagrams and looked in detail at the major subsets of the real number system, their relationship to each other, and examples of each.

Tuesday - Lesson 1.2: Number Lines, Opposites, & Absolute Value. This was a packed lesson as students reviewed number lines, coordinates of a point on a number line, the opposite & absolute value of a number as well as the length & midpoint of a segment on a number line.

Wednesday – Students learned about a career in mathematics. While I realize that few students know the leading of the Lord in a career choice at this point in their lives, it is still important to understand that the more math students learn, the more avenues of service will be open to them. Students should want to be used by God in whatever vocation He calls them to. On a different note, we spent the last half of the class looking at sequences, specifically evens, odds, & multiples.

Thursday - Lesson 1.3: Adding Rational Numbers. Students reviewed how to add signed integers and rational numbers. We also looked at the properties of addition which is foundational to success in Algebra.

Friday - Lesson 1.4: Subtracting Rational Numbers. As another foundational lesson, students reviewed how to rewrite subtraction as addition by adding the opposite as well as a review on subtracting signed integers & rational numbers.

As a part of this course, students are also working on rapid calculations on a daily basis. They are doing a great job on these.

Next week (Wednesday), we will spend time looking at their graphing calculators. On that note, it is one of the goals of this class to teach students how & when to use their calculators. So far, they have not needed them yet, but the time is coming!

If you have any questions, please let me know!

## Welcome

Hello Students and Parents,

The first day of class is just around the corner and I am super excited! If you would, please take a few minutes to do

1. Please watch this brief Intro. Video.

2. Please preview Lesson 1.1. This will take around 6-7 minutes.

Thank you for taking a few minutes to view these two videos. It will help us get off to a great start!

Note to Parents: Most homework assignments will include having students view a 5 to 10 minute mathematics video that will serve as a preview of the next lesson. Please help to make sure that your students are doing this portion of the assignments throughout the year. This is a vital part to the class!

Please contact me anytime if you have any questions. Looking forward to a great year!
