Announcements
Tuesday, July 1 - Test 4 solutions - Version A or Version B
Final tomorrow, July 2 at 11:00am in the classroom. You just need a pencil. I will provide the scantrons. It is 32 multiple choice questions that cover a little of everything.

Monday, June 30 - CHANGE IN GRADING POLICY - If the grade you receive on the final is HIGHER than your lowest test grade, the final grade will replace your lowest test grade.
The final still counts 24% of your course grade as in the syllabus. 

Thursday, June 26 -
Here is the last week of class schedule
Monday - Test Review for Test 4 and Cryptography Application
Tuesday - Last Day of Class
    10:00 TEST 4 Blue Book needed
    11:00 Final Review - handout final formula chart you can add your own handwritten notes
Wednesday - Final 11-2 in our classroom - no blue book needed - multiple choice

Test 4 - Lines, Properties of Mathematical Systems, Is it a group? Finite systems by the table and modular arithmetic

Tuesday, June 24 - Test 3 solutions Version A and B.

Monday, June 23 - TEST 3 is tomorrow. It covers material from June 16-20. You will need a Blue Book. You  WILL be allowed a calculator, but no extra notes.
We have class Monday, Tuesday, Wednesday and Thursday this week, NOT Friday. Then, we have class on Monday and Tuesday next week, and our final is Wednesday, July 2 at 11am in our classroom. 
Test 4 is different from the final, it will be Tuesday of next week at 10:00. The final is REQUIRED for all students. It will be multiple choice and will be comprehensive.  You will be given a formula sheet on Tuesday of next week, you will be allowed to add anything you wish to hand-write on the formula sheet for the final.

Friday, June 20 - We did ratios and proportions and formulas today in class. Test 3 covers up through today's material. The Extra Test 3 Practice Problems contains more problems on test 3 material. I will work some in class on Monday and post the solutions to all of them Monday.

Thursday, June 19 - We DO have class tomorrow, we will talk about proportions and formulas. We will talk about graphing linear equations on Monday, and the graphs will be on test 4 instead of test 3. TEST 3 is Tuesday, June 24 at 10:00am. It will cover order of operations, evaluating expressions, solving linear equations, proportions and formulas. You will need a blue book for the test.

Wednesday, June 18 - Test 2 Solutions Version A and B
The Completed Variables and Equations file is the first part of today's notes on determining if a value for the variable is a solution to the equation. It also includes an exponent example as asked about in class.

Tuesday, June 17 - Homework 10 will be posted tomorrow morning, I have to leave the office early for family logistics reasons. 

Monday, June 16 - Test 2 is tomorrow, June 17 at 10:00am in the classroom. You will need a Blue Book for the test and you will NOT be allowed to use a calculator. Test 2 covers real numbers and their properties, which is homeworks 5-8.

Friday, June 13 - There will not be a file of review problems for test 2, but here is the list of things you should know. We will do some review and start the algebra unit (chapter 6 in the textbook) with the order of operations on Monday. Test 2 is Tuesday at 10:00am. You will need a blue book and you WILL NOT be able to use your calculator.

Thursday, June 12 - We DO have class tomorrow, we will cover the properties of real numbers and exponents and scientific notation.
Here is a copy of the square root activity from today.
Homework #7 and #8 will both be due Monday.

Wednesday, June 11 - We did rational numbers today, which is section 5.3 in the textbook. The Extra Fractions Examples link in the lecture slides list is more practice doing fractions that was NOT done in class. Remember that homeworks 5 and 6 are due tomorrow.
Test 2 will be next Tuesday, and you will NOT be allowed a calculator (you need to know the rules for the operations with real numbers without the calculator to do it for you)

Tuesday, June 10 - Test 1 solutions A and B. We will do rational numbers tomorrow.

Monday, June 9 - Test 1 is TOMORROW at 10:00 during our regular class time. It is a 50 minute test. You will need to bring a BLUE BOOK to the test tomorrow.
After the test, we will continue where we left off in negative numbers and start fractions.
Change in the course calendar - Homeworks 5 and 6 are now both due Thursday, June 12.
Homeworks 7 on Irrational numbers and 8 on properties and exponents will be posted by tomorrow afternoon or Wed morning and will be due next Monday. (so there will be no homework turned in on Friday, but we WILL have class this Friday)

Friday, June 6 - We discussed prime numbers, prime factorizations, GCD and LCM.
Test 1 covers all the material from this week, including today's lesson. We will do some review on Monday and the test is Tuesday. You will need a blue book for the test. I will accept Homework 3 on Monday. Homework 3 and 4 solutions will be posted Monday after class.  I do not have internet yet at home, so if you email me a question this weekend, I will not see it till Monday morning.

Thursday, June 5 - We discussed arithmetic with natural numbers today. You need to know the terms for the different understandings of division, and the understanding of multiplication as faster addition for TEST 1, so learn those. I will NOT test over multiplication in other bases. We have class tomorrow, we will discuss prime numbers and prime factorization. TEST 1 will cover up through tomorrows lecture material, and will be next Tuesday at 10:00am.

Wednesday, June 4
1. We have class on the first three fridays of June - June 6, 13, 20!! Check the course calendar above for homework due dates and test dates.
2. Homework #2 - the last problem will NOT be one of the ones graded since we did not quite make it that far in class today.
3. Test 1 is Tuesday, June 10 during the first hour of class. It covers the first week of class on systems of numeration, other bases, arithmetic with natural numbers and primes. There will be a review time on Monday, and the best preparation is to make sure you understand the homework. You will need a blue book for the test (one with at least 5 pages)
