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.

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.

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.
