**Today: **We reviewed mean, median, and mode with my birth year in there and without my birth year to see the difference it can make. We then took the questions you did for homework and put them on posters around the room so we could answer them.

**Homework: ** None.

**Next Class: **We will finish with the data you collected and look at how we can display that data most effectively.

**Today: ** You finished your FOIL investigations and began working on using what you have discovered.

**Homework: ** p. 508/ 20, 21, 27, 29, 42, 43, 45, 51.

**Next Class: **We will look at a few more “fun” problems with multiplying polynomials. You are almost ready for a test! Yay! We will have one after Lunar Break!

**Today: ** We learned about the infinite and finite geometric series. We also learned that infinite series can converge or diverge. If it converges, ten it has a limit which is a sum that can be found using the formulas. If it is divergent, it has no limit and just goes and goes and goes. We practiced using the formulas, realizing that most mistakes are going to be made with the exponents and the order of operations.

**Homework: **p. 628/ 1, 3, 8, 9, 13, 15

**Next Class: **We will review for your test after Lunar. It will cover the first five sections of this chapter (Chapter 11). We did not do area under the curve. We have talked about arithmetic sequences, geometric sequences, arithmetic series, and geometric series.

**Today: ** We finished the other triangle congruence shortcuts that will make triangles congruent. We also talked about how right triangles have their own congruences, but those congruences use the ones familiar to us. So it’s really not necessary to memorize those too. However, right triangles do have their own congruence that is unique to them – HL (Hypotenuse-Leg).

**Homework: **You have a worksheet packet. Your homework is to complete the first two pages of the packet. You can finish the third and be done with your homework for Friday, if you wish.

**Next Class: ** We will continue working with triangle congruence. We will check the worksheets and then take a quiz on the first sections of chapter 5: Sections 5.1-5.4. After you have completed the quiz, we will practice with proof puzzles.

**Homework: ** p. 508/ 20, 21, 27, 29, 42, 43, 45, 51. I think I left one out… If you can see which one it is, please leave a comment on the blog — Thanks!

**Today: **We discussed the above measures of central tendency and range. We looked at the class’s birth years and tried to find a number that would represent the class as a whole. You came up with other questions and thought about what average means to you.

**Homework: ** Make sure your questions can be answered with a number and is interesting to know the mean, median, and mode of.

**Next Class: ** We will continue working with these measures of central tendency.

**Today: ** You began your FOIL investigation today. Some finished, noting the general rules.

**Homework: ** None.

**Next Class: ** We will have more time with the investigations. We will also begin working on the next piece.

**Today: **We talked about China and adding up the bricks in the courtyard! This was my really cool example for a real-life arithmetic series! My parents really did question my perseverance (OK obsession) in finding the formula! We then skipped to Gauss’s question of finding the sum of the first one hundred numbers. We noticed a pattern or two and developed the formula for the sum of a finite arithmetic series. You guys are so smart!

**Homework: **p. 622/ 1-17 odd, 31.

**Next Class: **We will review and discuss the geometric series formulas. These series formulas will be given to you on the test, so you do not need to memorize them. Remember your test will be after the Lunar holiday.

**Today: **We went over the notes you were supposed to take last class. We had time to practice with SSS and SAS.

**Homework: **p. / 9-21 odd, 34, 36-38.

**Next Class: **We will work more closely with ASA and AAS. We will also see what happens next when we know the triangles are congruent.

**Today: ** Those of you who did not email me had to email me, and I answered the questions (very quickly) of those who did email me. You began your FOIL investigation today. Some finished, noting the general rules.

**Homework: ** None.

**Next Class: ** We will have more time with the investigations. We will also begin working on the next piece.
