Usual Day at Unusual School

Today I answered any questions still remaining about concepts for the chapter 2 test. Please keep in mind that I will not be here Monday and Tuesday of next week, but we will still have a test on Wednesday!
After questions we put on a small classroom "play" of A Usual Day at Unusual School. The objective was to figure out who was a "bright" and who was a "brave." This was just a review of how truth tables work. Be sure you review old material because the tests are cumulative.

Coming up:
- No homework tonight!
- Tomorrow be sure to meet OUTSIDE at the picnic tables. We will then walk over to the courtyard steps by the gym! Be on time!

Where do we meet tomorrow?

Group Experts

Today each of you became an expert for one section of the recent material. Sections covered in the review groups were: sec. 2.1, 2.2, and 2.3. Keep your "perfect notes" in a safe place! We will not be moving on to any new material before the next test.
Keep in mind that you should be studying NOW for the test. I will not be in class Monday or Tuesday, but the test will be Wednesday. You will have a review sheet next week and answers will be provided prior to the test.

Have a great day!

Coming Up:
- Homework: You have no homework other than studying for the test!
- Test will be one week from today (October 3rd)

When is the next test?

Test Prep

Today we went over the homework dealing with onto and one-to-one functions, as well as ceiling and floor functions. Be sure to check your homework if you were not in class today. We did not go over any new material and we will not start anything new until after the test. That gives us several days to review (and we still have a few activities dealing with this material).

For homework everyone should generate 3 questions about the material (sets or functions) that you do not completely understand. We will begin reviewing tomorrow in preparation for the BIG TEST next week. The test will cover mainly sets and functions, but remember that the old material from propositions and fair division might be on there (as the cumulative questions). Your questions for homework can be directly about the material (ex. what is a ceiling function), or they can be book problems that you still do not understand.

Have a great day!

Coming up:
- NO HOMEWORK tonight unless you did not finish your 3 questions in class!
- We will have a big test next Friday (October 5th), or possibly Wed. (Oct. 3rd)

How many questions do you need to generate for homework?

Onto and One-to-One

Today we looked at onto functions and one-to-one functions. Although these two definitions can be confusing, the reference pictures on page 139 should prove to be helpful. Remember that a function is onto if every y is used, and a function is one-to-one if each y only has one arrow pointing at it. We also briefly discussed ceiling and floor functions.

Have a great week!

Coming up:
- Homework: pg. 146 #'s 8-11, 32
- Remember to make up your quiz by Wed. if you have not already
- We will have a big test next Friday (October 5th)

Is this function onto or one-to-one: (a, 1); (b, 2); (c, 1) Domain: {a, b, c} Range: {1, 2}
