Algebra 2 Week 22

We started the car project today. The videos explanations are on YouTube now. It would be wise of you to do your spreadsheets very soon. Even if you don’t have a price for your car you can make the spreadsheets with a fake price and substitute yours in later. The calendar changed this week. We didn’t have a lesson for 8.8, you can substitute working on your Car Project for that lesson. There is a review and test this week. We took a Formula Madness quiz in class today. This was the last of the level 3 quizzes. There is no FM quiz to take at home this week. I will be giving you level 4 next week to start practicing. There will be no class next week we are having break. This will give you time to work on your car project. The video for section 8.7 is posted on YouTube and on my blog. Please let me know if you have any questions.

Algebra 2 Week 16

Yesterday was a small class.  We started the semester running. We are going to spend the next 2 weeks finishing up Unit 6. All of Unit 6 will be covered on the final exam for second Semester. You have been describing the graph of a polynomials. It is like you are learning how to be detectives for polynomials. You are learning ways to detect attributes of the polynomials by looking at its equation. You also added to our formula madness formulas. Please just practice the new items, you will not have a quiz over these until week 18.  We have 3 lessons and a quiz this week. Please text me any questions you have. I truly want to help.

Algebra 2 Week 15

Yesterday was the last day of Algebra for 2019. I am so proud of the progress these students have made. In class we went over problems that will be on the semester final. I want to remind all of you that the final exam is worth 200 points. There is an optional memory verse worth 10 extra credit points. Don’t forget that there is one more formula madness quiz also. After you have taken the test you have several options. You could mail it to me, you could bring it to me, or you could keep it until the next class. Speaking of the next class, I plan on starting up January 6, 2020. There is no extra supplies needed for the second semester. I have so enjoyed teaching everyone this subject. I pray that each of you has a Merry Christmas. Please let me know what I can do to help you finish up first semester Algebra 2.

Algebra Week 14

Today we had our last class with notes and explanations. Next week we will be studying for our final exam. We covered 3 lessons today. We started learning about polynomials and how to add, subtract, multiply and the beginnings of graphing them. Don’t forget to learn your memory verse so that you can get extra credit on the final exam. I also want to remind you that the reason that your lessons are longer this week is because we started studying for your final exam. I have provided problems from the beginning of the school year. Please let me know if you have any more questions. I really want to help.

Algebra 2 Week 13

Everyone was in class and having fun. I know that each of you don’t like the work, but you give me the impression you at least don’t mind doing your work together in class. We seem to smile often as we do our work. Each of you are working hard in this class and I want to let you know that I appreciate it. We looked over the calendar and we are following it as printed. There will NOT be class next Monday. Have a wonderful Thanksgiving with family and friends. Yesterday we covered 2 topics and the videos are almost uploaded to Youtube. The reason we only had 2 topics is because we have a test this week. Please don’t forget to take the formula madness quiz that is assigned also. After you read this please press the heart at the side for extra credit. Your parent can click the heart for you and you will receive extra credit. If you have questions please take a picture of your work or the problem or tell me the problem number, and text it to me. You can also send it through GroupMe if you like. Please remember that you are not bothering me with your questions. You may need to wait for a response, but it is not a trouble for you to ask me questions.

Algebra 2 Week 12

Yesterday we covered 3 sections in our unit on Quadratic Equations. We are exploring methods to solve and graph them. This week don’t forget to take the formula madness quiz at home and bring it to class to turn in. Just follow the calendar for the rest of your assignments. Thanks for your hard work. We have 3 more classes before Christmas break. Keep working hard the time for a break is soon and then you can relax.

Algebra 2 Week 11

Yesterday we had 3 topics to cover in class. This meant we needed to be very attentive to finish on time. We continued our graphing of parabolas, and started solving quadratic equations. We took our first formula madness in class and graded it so that each student can see what must be done to improve. Continue to practice for your formula madness quiz. You will print out the next one and take it at home. The video for the week is almost ready. It will be on YouTube by tomorrow morning. Let me know if you have any questions.

Algebra 2 Week 10

Yesterday's class went so smooth. I could tell that the students had studied for their formula madness quiz. This helps tremendously when we're doing our lessons. I want to remind you that we will be having a formula madness quiz in class next week for a grade. We studied more applications and did them with our graphing calculators yesterday. The first section we did yesterday we did all on a graphing calculators. This was to get ready for our test. The test will have two parts, one with the graphing calculator and one without.  Parents please make sure that when you give that test that you ensure that they don't use a graphing calculator on the appropriate section. This also includes the review sections, I intend for these two to be done as one assignment. There's just a practice one with the graphing calculator and one without. We covered only two sections yesterday  because there will be a test this next week. The second section started graphing quadratic equations. This was very similar to graphing absolute value equations. If you have any questions on this weeks assignments there will be videos on YouTube, you can text me, or send a message on GroupMe.

Algebra 2 Week 9

I want to start by saying that I am so proud of everyone on your hard work. I feel so privileged to teach each of you. Today students were to hand in Test 3. I have sent out progress reports to everyone. Please look them over and let me know if you have any questions. The new unit is covering topics that are not review at all. These topics are brand new and difficult. Something that will make it easier to understand for now and in the future is to memorize everything on formula madness level 2. We will continue to be introducing new topics for the rest of the year. If you have the formulas memorized you will do better. The best thing that you can do is do your homework each week, and ask questions to me when you don’t understand. Don’t let your work pile up. It will be hard to understand. I really want to help, do ask me questions. Those of you who do ask me questions don’t stop! Another thing that will be helpful are the videos on YouTube. Make sure you refer back to them. Please refer to your calendar for the assignments this week. Today we talked about having class on ???, so we could get out for Christmas break earlier. This would mean that you would need to do school during what is normally Thanksgiving break. PARENTS WHAT DO YOU THINK? Students talk it over with your parents and let me know. You may have relatives coming or you are traveling and you will not be able to do work during that week. I will be putting this recap on GroupMe but archiving it on my blog. I hope this helps everyone to be able to read it each week. Please let me know if you have any questions about anything. See you next week.

Algebra 2 Week 8

We finished our study of systems of equations and introduced matrices. The last section of the systems of equations was more story problems. Most students feel that story problems are difficult. I hope I gave them so tricks to doing these. Make sure you ask questions or watch the YouTube videos if you don’t understand. We started Unit 4 Matrices. These are just boxes to organize data. We learned how to add, subtract, and to do a type of multiplying called scalar multiplication.  I will be teaching you how to do them on your calculator. I challenged you to experiment to figure out how to do these on your own. You can play around or consult Google if you want. I also introduced the second level of the formula madness. I posted the answers for these in the Parent folder. You have 2 weeks to practice this before the official quiz. I will be surprising you next week with a in class quiz to see how you do and to see how many of you read these wrap up paragraphs. The quiz will just be for practice and not a grade. The practice quiz will have 20 questions even though level 2 only has 14 new formulas. I will take formulas from level 1. You don’t know what formula I will be taking. There is a review and test this week. Make sure you are successful on the review before you take the test. If you are not successful please get some help from me or someone else. I will have the videos up soon for the lessons. Let me know if you have any questions!

Algebra 2 Week 7

We continued learning about systems of equations and inequalities today. Last week we solved them by graphing, but today we solved them with algebra and technology. The algebra portion was called substitution and elimination. We also furthered our knowledge of our graphing calculator and solved equations that cross at rational numbers.  This week we will have 3 assignments, 3.3, 3.4 and 3.5, and quiz 3.2. We will have the last formula madness quiz for level 1 this week. Make sure you take it and bring it to the next class. Speaking of the next class, we will not have class next week. It is fall break. We will meet again on October 14. As always please let me know if you have any questions.

Algebra 2 Week 6

Everyone was here today. This coming week is a review and a test. We covered 2 lessons for the next unit. In 3.1 we are learning how to solve linear equations by graphing them, then in 3.2 we solved them by graphing them on our calculator. We sailed through these by watching me do some explaining and then doing several of them in our homework. We had about an hour left in class so we all worked on the Unit 2 Review together. We did the whole thing together. I wanted to work out any problems that everyone may have had. So that they feel confident on the test. I can send worksheets of any of the problems for you to do for more practice. I can also send out another review to do at home. I can make it have different questions. Please let me know if that would be helpful. You can watch the videos for more review. Please let me know if you have any questions. I would love to help all of you.

Algebra 2 Week 5

We had 2 students gone for class this week. We missed you both. One was able to attend on Google Hangouts. We used technology this week to simplify our life and to discover patterns. I have a demo on my blog to help you make scatter plots and find the best fit line (linear regression) using both Excel or Google Sheets. We also used our graphing calculator in class to discover the “trick” to finding the vertex for absolute value graphs. In the process we learned how to use it to graph equations. As a result we found that after we learned the “trick” it is easier to just put the calculator aside and do it faster without it. There are 3 lessons this week 2.6 had the  computer linear regression and also an extension of writing the equations of a line. We extended it to writing the equations in standard form. On 2.7 we now extended the graphing linear equations to graphing linear inequalities. For these we need to have solid or dotted lines, and we need to shade the result. For 2.8 we learned to graph absolute value equations and noticed some similarities with graphing lines, especially the slopes, but we have a vertex now. After using the calculator to find the pattern we had were able to fly through these. Please let me know if you have any problems on any of these and I can point you to some help. See you next week.

Linear Regression on Excel or Google Sheets

You will be doing some of your assignments on the computer. It is important for you to use the modern technology to do your math work. I am giving you the instructions to do that here.

Algebra 2 Week 4

Today was extraordinarily fun. Each student was engaged and doing the problems, but we were able to have some jokes too. Each of them work so hard and feel comfortable to asking questions of me and each other. They are so fun to teach. Despite the technical issues I had at the beginning, we had time to do some of extra homework problems together after class. Please look at the calendar. We covered 3 topics in class today Graphing Linear Equations (2.3), Writing Linear Equations (2.4), then last Linear Regression 2.5. You will have a quiz this week.  Don’t forget to do your Formula Madness Level 1C  this week AT HOME. Bring everything to class to turn in to me. I will be sending out grade reports soon so you can see how your are doing. Please let me know if you have any questions.

Algebra 2 Week 3

This week your student will take their first test. There is a review assignment that is very similar to the test. Today we covered some helpful buttons on the calculator, an introduction to functions, and slopes of lines. There was only 2 new sections for homework. I am suggesting the assignments in this order, (1) review, (2) test, (3) 2.1 Introduction to Functions, and (4) 2.2 Slope. There is also a formula madness quiz that must be taken at home. We took one in class his week as a model. The quiz is 5 minutes over the same questions that we took this week. It is just a way to keep the material in their heads. Please bring all the assignments, test, and formula madness quiz to the next class.  Next Monday is Labor Day and we will not have class. Please send me questions by taking pictures of your homework paper or telling me the section and problem number  from the assignment you are needing help. I can send a video explaining the problem. I look forward to class in 2 weeks.

Here are the videos for this week:

Algebra 2 Week 2

Today was our second class of the year. We had some technical issues with the projector and the computer, but we just pulled out the old fashioned white board and did them the old school way. We did some time worked and distance word problems, these type of problems can be difficult so make sure you watch the video if you need it. We will be expanding on these types of problems in the future. The next sections were review from Algebra 1. We solved and graphed inequalities and compound inequalities. Then last we solved absolute value equations and inequalities. I want to thank Natalie for giving us some memory helps for the formula madness problems. There will be a quiz in class NEXT week. We will have our first Formula Madness quiz in class next week. You will have only 5 minutes to write down 20 formulas. Make sure that you study each day to put these formulas in you head. Consult the videos if you don’t understand any of your homework, and please ask questions of me by either GroupMe or text. I can send a video to help.

Here are the videos for this week:

Algebra 2 Week 1

We had a jam packed and fun first day of class. We went over the syllabus. Please take some time to read over it so you will understand the procedures for class. If you have any questions please ask me by text or GroupMe. This years theme is discipline, humility, and taking responsibility. We will be memorizing scripture, for extra credit on tests, that cover these topics. Today we watched a video that emphasized these topics. I invite you to watch it here. Then we dove into 3 lessons. These lessons were review from Algebra 1. In the lessons we covered the topics: order of operations, simplifying expressions, solving equations, and solving literal equations. The last thing we covered was the answers for the formula madness quizzes. I have made videos for each of these topics. They are on my blog or on YouTube. They will be edited and uploaded by morning. If you don’t understand you can watch these again, or send me a GroupMe text asking me a question. I want to help! We will not meet next week. I had a great time today. Let me know if you have any questions.

Here are the videos for this week:

Week 30

Today was the last day of Geometry class. I can’t believe that we have been together for an entire school year. I am so proud of each of them for all the hard work they have put into geometry . You have grown academically and also as friends. For those who are not coming back next year we will truly miss you, and we look forward to seeing those who are coming back. I think that the you want a break before they do more math though.

Today we had a treat. What do you get when you put a sphere on top of a cone? Well something that looks like an ice cream cone. I brought out my ice cream scoop, they traced it on their paper. Then they were to find the center, and measure the radius. We did the same thing with a sugar cone. We found the center of the cone and measured its height. Then we had enough information to find the volume of both. Then I served up Ice cream on the cone. After that we did problems together to study for the final exam.

There are 2 assignments to study for the final exam, we worked on the first one one in class today. These assignments are very large with 75 questions. The final exam is very large, with 75 problems. If you are proficient with the review assignments then you are ready for the final exam. The final exam is to be taken at home just as all the tests before. It is worth 200 points. There is a memory verse for extra credit. It is worth 10 extra points on the test. There was no video for class today, but if you have questions on any of the review problems, I will make some videos and post them on GroupMe for you. Just make sure you request the problem number and assignment name.

I have never had a class that everyone worked so hard like this before. I want you to know I feel blessed to have been a part of your lives. Thanks for being a part of mine. Please let me know if you have any questions.
