MATH 811   NOTES ABOUT HOMEWORK, ANNOUNCEMENTS, ETC.

 

Assigned on:

After introducing examples of a new section, I assign a range of problems from the current section for you to select work from. You should try the odds in that range, check the answers in back, go to tutoring, etc., and bring questions to class.

BE SURE TO CLICK ON RELOAD/REFRESH ON YOUR COMPUTER OR THE CURRENT ADDITIONS TO THE PAGE MAY NOT APPEAR!

W 1/17

We talked about the place-value system in section 1.1. You should be able to do problems like p7 #23-30.

We then briefly talked about the addition problems in section 1.2. You should read thru the section and see if you have any questions. Homework will be assigned next time.

We ended with talking about how multiplication is really repeated addition, and that for future work, you must either memorize your times tables up to 12x12 or use the repeated addition principal to find the answer. For example, if you wanted to find 4x6 and did not have the answer memorized, you could also say that if means add 6 to itself 4 times: 6+6+6+6=24, so 4x6=24 !

F 1/19

We went over the concepts above again, and got a start on subtraction in 1.3. Homework #1 due Monday 1/22

is to do 1.3p20 #2, 18, 20, 24, 30 and turn it in to me (write out your work on a piece of paper—do not just show me work you did in your book!).

You will be quizzed (Quiz 1) on Monday 1/22on section 1.1, 1.2, and the multiplication table. The quiz will last only 5 minutes, so please be prompt!

Show all prime factors for each number, then use them to cancel.

Try the 2 problems from the book: 2.6 p.132 # 39, 42 and the following:

 

 

 

If you came to class on Weds. but did not turn in the assignment, here are a few more problems to make up for it (since we went over them in class!):

 

 

 

 

To those who did not pass the Unit 1 test on Friday, I sent you an email if you had one on file, but I am putting a copy of the message here in case you did not:

As per the syllabus at http://www.smccd.net/accounts/callahanp

“For each scheduled unit test, if you

   1.  do not qualify to take it,

   2.  fail to show up to take it as scheduled, or

   3.  fail to pass it,

you may earn a maximum of two more chances to take it. You must spend at least 4 new hours (sometime after the test) in the tutoring lab to qualify for each new attempt. If you do not pass it before the next scheduled unit test, you will be dropped from the course. You must show evidence of making progress with the material to continue in the class. If you are dropped, you will receive “No Credit” for the class and may not continue coming to class. You should continue study the material in the book (with the help of the tutoring lab) and attempt the placement test again at the testing center to try to qualify for Algebra.”

 

To make sure that you are spending the required tutoring time in

16-166, you must log in to the computer and log out at the end

of your session AND you must have the following filled out:

 

MATH 811 Tutoring Slip

 

Student name: ____________________________

 

The student above is required to show proof of 4 hours work in the tutoring lab 16-166 and must receive a sign-off from a tutor on duty that at least one question was asked of the tutor for every half hour spent in the lab. This includes asking the tutor to look at a problem completed in the lab, or asking how to do a problem.

I will give you a better copy in class on Wednesday if you need it, or you may print it out from your email or this page. This obligation is not negotiable. If you did not take and/or pass the test, you did not meet your obligation and must make arrangements to make it up. It is in the class schedule that when you sign up for this course you are available to spend the “hour by arrangement” time outside of class. Check with the tutoring lab in bldg. 16 room 166 and see that they have a lot of hours of tutoring available.

W 2/28

We worked on the use of primes to cancel factors in a multiplication problem and then talked about how division is a form of multiplication. So in 2.7, if you flip over the fraction after the division sign, it turns into multiplication and then you can do the same thing you did in section 2.6!

 

If you came to class on Weds. but did not turn in the assignment, here are a few more problems to make up for it (since we went over them in class!) or just use them for practice!:

 

 

 

 

 

Homework due on Friday:

2.7 p141 # 10, 14, 18, 26, 30

 

F 3/2

After class, I checked with the tutoring lab, room 16-166 and they said none of my students had checked in for help! If you go, go to the computer and log in/log out with your student ID so that we can keep track of who is receiving help. The funding for this free tutoring depends on it! And if you did not pass the first Unit Test, it is mandatory that you go…do not put it off! From 9 to 1 there are 2 tutors on duty and all other times at least 1 tutor. There are also tutors for higher math in 16-168 and if they are not busy, they might be able to help you too!

Homework: 3.1 read the section and do p156 #4, 6, 10, 14, 20.

The answer to the quiz was: 51/10 divided by 43/10 = 51/10 multiplied by 10/43. The 10 in the top and bottom cancel to leave 51/43 which as a mixed number is 1 and 8/43.

 

Note that your Unit 2 test will occur on Weds. of next week. It will be made of one question from each of the following sections:

 1. section 2.6 multiply fractions

 2. section 2.7 divide fractions

 3. section 3.1 Find the LCM                                                              

 4. section 3.2 Add and simplify fractions     

 5. section 3.3 Subtract and simplify fractions
