02/01 Welcome to the first day of class!!!

I will talk about structure of the class and answer any questions that come up, then we will cover the following topics:
1.1 Introduction to equations
1.2 Combining like terms


Online resources: I will not be reviewing fractions: how to write equivalent fractions, how to add/multiply/divide/subtact/simplify fractions.
If you need a refresher, visit this resource: https://openstax.org/books/intermediate-algebra-2e/pages/1-3-fractions

Here are the video recordings from our class meeting:
1) Introductions + class structure
2) Covering Sections 1.1 and 1.2 from zyBooks (part 1)
3) Covering Sections 1.1 and 1.2 from zyBooks (part 2; we have two parts because there were technical issues on my side)
HW 01, due Monday, February 8th, 11:59 pm
at WeBWorK

Few notes:

* start working on the homewors as soon as possible after our class meeting. Do not delay it, do not set it aside, do not start working on your homework on the due date!

* Please note that if you try to submit an answer at 11:59pm, it might not be accepted by the WeBWorK as time on your computer and time at WeBWorK server might slightly differ!

* If you have a question about a problem at WeBWorK, hit the "Email Instructor" button at the bottom of the page of the problem.

* Although MathQuil, that helps enter fractions, exponents, etc., is enabled for our class, see the cheat sheet for the correct syntax for entering answers in WeBWorK if you do not want to use MathQuil WeBWorK Cheatsheet for Students Ver2.pdf
02/03
Class meeting plan:
  • Anytime before our class meeting or from 12 pm to 1pm you are to go over section 1.3 Linear Equations at zyBooks and do all the participation/challenge activities.
    Note that all these activities must be completed by 1pm to get the points for it.
    If you have any questions, I will be available at our Zoom meeting to answer them.

  • at 1 pm we will begin our training session:
    It is assumed that you read section 1.3 and did all the participation activities by now.
    We will see more examples and will work on more problems during this period.
    We will also have a Kahoot! quiz, so make sure you installed the app on your phone.


topic:
1.3 Linear equations

Update from Thursday, Feb. 4th on what did we do at our meeting:

1) We went over these problems for practice. Here is the video recording.

2) Then we had a Kahoot! quiz which was based on the material from Section 1.3
This was a training quiz and the results will not be counted towards your grade ... unless I decide to use them as extra points.

3) We didn't have time for our second part of the practice and these problems I did not cover with you in class.
I plan to show you two examples from this set in our next class meeting on Monday (the ones with "no solutions" and "infinitely many solutions"). The rest I leave for you to look over. All these examples employ fractions. HW 02, problems 9-16 are dealing with this type of questions. Here are the solutions to most of the second part questions: problem 1, problem 2, problem 3, problem 4, problem 8, problem 9, problem 10

Additional online resources:
1) Here is a whole chapter of short videos and guided practices from Khan Academy
2) Sal from Khan Academy solves the literal equations ax+3x=bx+5 and a(5-x)=bx-8 for x (video, ~5 mins long)
3) Sal from Khan Academy rewrites the formula for the perimeter of a rectangle so it is solved for width (video, ~7 mins long)

2) Today's zyBooks activity are also extra points - in case if you want to boost your zyBooks activity score.
3) Check out the Google spreadsheet, Final Grade page. I posted the class grade without Final Exam. It doesn't use the Spring Grade Boost points yet, as it is impossible to predict what should be added to until you take the Final Exam.
Feel free to email me with any questions you have!
4) I need to cancel office hour tomorrow (on Thursday), so if you need to speak to me, send me an email and we will find time to meet.

05/17 Discussion of Final Exam and its structure,
test-taking strategies,
few notable examples

Dear All, I have a really bad allergy today and can barely talk, so I had to cancel our class meeting.

However, I was able to have the other section meeting. Here is the video recording.

In this video I'm talking about the final exam preparation there, test-taking strategies, and work on 16 examples. Please make sure that you watch it.

Few announcements:
* Our Final Exam is next Monday, 12pm to 1:50pm. Make sure you connect to our meeting - I need the clear videos of you (not the pictures of you!), otherwise you will be considered as "not attended the Final Exam" and "didn't take it"!. The Final Exam will be at the WeBWorK: 25 questions. I will send the announcement about the Final Exam tonight or tomorrow during the day.

* Please check our Google spreadsheet - the last tab, "your overall class grade without Final exam and booster points" - it will give you an idea of where you stand right now.

* And feel free to send me an email if you have any questions
