Jan. 16, Friday

Hi Contest Math!

Happy Friday

My Top Ten Guys (actually, 12 students): Continue working on your packets. Quietly practice the concepts. Take breaks if you need to! Enjoy your snack in class, and please clean up after yourself. Good luck! I will be back to help you practice :)

Other Mathletes: You have 3 options. You must work individually and silently. Continue yesterday's activity using this packet...

1. Use the Doceri App and show me how to solve AT LEAST 5 problems. It is very easy to use...create a video or step-by-step images to explain how to get the answer.
2. Use iMovie to work on AT LEAST 5 problems using my whiteboard or a piece of paper...put effects, captions, music, etc.
3. Use paper and make posters for the OLD BOOT GAME TODAY at 2PM

Keep working on this until you are dismissed for lunch. 

Not doing what you're suppose to do? Forgot iPad? Talking and being disruptive?
PUT YOUR IPAD ON MY DESK AND Grab a textbook from the shelf... You must work on this as classwork:
6th grade: Lesson 70 #1-30 all
7th grade: Ch. 7 Sec. 1-6 CheckPoint Quiz #2 pg. 370 #18-25 and 1-12 all
8th grade: Ch. 7 Sec. 1-5 pg. 463 #1-48

Have FUN working on this! Be very respectful to Ms. Feroza and enjoy solving word problems in a creative way! HAVE A GREAT WEEKEND! :) - Mrs. Rashid

Jan. 15, Thursday

Hi Contest Math!

Miss you all already!

My Top Ten Guys (technically, 12 students): Start your packets today if you haven't yet. Quietly work on your material and practice. Take breaks if you need to! Jayaram, since you left early yesterday, grab your packet from my desk. ONLY THESE STUDENTS MAY BRING AND EAT A SNACK during electives. Please start bringing a snack to nourish your minds while working. Good luck! I will be back to help you practice :)

Other Mathletes: You have 2 options. You must work individually and silently. Using this packet...

1. Use the Doceri App and show me how to solve AT LEAST 5 problems. It is very easy to use...create a video or step-by-step images to explain how to get the answer.
2. Use iMovie to work on AT LEAST 5 problems using my whiteboard or a piece of paper...put effects, captions, music, etc.

Keep working on this until you are dismissed for lunch. We will be selecting our MOVIE TEAM and I need to see your skillz (I mean skills, haha). 

Not doing what you're suppose to do? Forgot iPad? Talking and being disruptive?
PUT YOUR IPAD ON MY DESK AND Grab a textbook from the shelf... You must work on this:
6th grade: Lesson 70 #1-30 all
7th grade: Ch. 7 Sec. 1-6 CheckPoint Quiz #2 pg. 370 #18-25 and 1-12 all
8th grade: Ch. 7 Sec. 1-5 pg. 463 #1-48

There are 2 students, in particular, who have been not following directions with their iPads lately by downloading Apps there are not suppose to have...you have been warned. Even though I am not there, there is no excuse for you to be doing what you are not allowed to do. I am giving you one last chance to prove to me you can handle the PRIVILEGE of having an iPad in class. Don't make me regret it. <not giving names>

Have FUN working on this! Be very respectful to Ms. Feroza and enjoy solving word problems in a creative way!

Jan. 9, Friday: Top Ten MATHCOUNTS Team

Hello everyone!

I am happy to announce our top ten students for the 2014-2015 MATHCOUNTS Competition!

(In not particular order, except grade level)

8th: Satoshi M., Troy L. and Erkan B.
7th: Jia K., Ali J., Neil V.
6th: Abel J., Sam F., Connor S.
Tied for out last spot (competing on Jan. 13): David-Tyler I., Jayaram J., Ethan K.

Jan. 8, Thursday: Classroom Competitions in January

You may be thinking I am avoiding you since I have been out for our elective for the past 3 days... and you're right. JUST KIDDING!

Sorry I am out again...I hope to be in tomorrow. As usual, be wonderful for the substitute and follow all directions on this page. If not, I will rename "Sam's Exit".

First of all, I would like you to know that tomorrow, Friday, Jan. 9 (when I'll be in), I will announce our Top 10 students for our MATHCOUNTS Team. This list was determined by the following:
#1: Your participation/enthusiasm in this class
#2: Your score on the Math TMSCA Tests (Practice and Actual)
#3: Your grades in your math class with me
#4: Your attitude!
There are 3 students tied for our last spot. Next week, we will have our final list when those 3 students compete in Sprint Rounds! I will explain EVERYTHING soon. If for some reason I cannot come in tomorrow, the list will be posted right here tomorrow at 11:50 AM.

For the remainder of the month, we will continue to practice as a class...

Look at this document. Read it.

There should be at least 20 concepts you are "not sure or have no clue about". In your Contest Math binder, grab some notebook paper and write down those 20 concepts and all the notes that follow it down (#1 being the most challenging/confusing thing you have ever seen). YOU WILL TURN THIS IN TO ME WHEN I RETURN. Do not waste your time and, although you may be hungry (lunch is almost here), concentrate and finish this task.

Once you are done, please start quietly studying the MATHCOUNTS "Bible". Silently work until you are dismissed. Expect a treat when I come back ;)

Jan. 6 and 7 Contest Math Activities

January 6, Tuesday

Sorry, I am out today. Please be on your best behavior with the substitute and work on what I have instructed below. I ask you to make sure your peers are also following directions as there will be SEVERE consequences (confiscation of iPad and detention) for not doing what you are supposed to do.

Go to this site. Answer all 101 questions. You may tap to see other responses. The purpose of this activity is for you to think critically and help you develop mathematically questions by analyzing images and videos. It's quite interesting but please do not talk while you are completing this task.

January 7, Wednesday

Finish working on what you were doing yesterday. Rewrite the following MathCounts "Bible" in your Contest Math Notebook on notebook paper. This is very important set of notes as I will require you to memorize it. Start off today by reading and writing the material. I will go over the material with you when I return.

1. Squares and square roots: From 1² to 30².
2. Cubes and cubic roots: From 1³ to 12³.
3. Powers of 2: From 2¹ to 2¹².
4. Prime numbers from 2 to 109: It also helps to know the primes in the 100's, like 113, 127, 131, ... It's important to know not just the primes, but why 51, 87, 91, and others are not primes.
5. Sum of the numbers in an arithmetic series: In an arithmetic series the difference between terms is a constant. Example: 4 + 10 + 16 + 22 + ... + 100 is an arithmetic series. The formula for the sum is
   n (a + z) / 2
   where n is the number of terms in the sequence, a is the lowest term, and z is the highest term. Finding the sum of the above sequence:
   17 (4 + 100) / 2 = l7 * 104 / 2 = 884
   Why is n equal to 17? Figure it out.
6. Triangle or triangular numbers: 3, 6, 10, 15, 21, 28, 36, 45, 55 are triangle numbers. (This is based on V. above!)
   n (n + 1) / 2
   To find 1 + 2 + 3 + 4 + 5 + ... + n, just take n, multiply it by its higher consecutive number, and divide by 2.Example: find 1+2+3+4+5+...+28.
   
   28 (28 + 1) / 2 = 406
7. Pythagorean Theorem: Applications of this famous relationship occur very often in math competition and on the S.A.T.
   a² + b² = c²
   1. Pythagorean Triples: Integral values of a, b, and c, where a, b, and c are relatively prime:

      3 - 4 - 5 (the most common)
      5 - 12 - 13	8 - 15 - 17
      7 - 24 - 25	20 - 21 - 29
      9 - 40 - 41	12 - 35 - 37

   2. The 45^o - 45^o - 90^o right triangle, or right isosceles triangle: This is half of a square, where the legs are congruent. If the leg is s, then the hypotenuse is s * sqrt(2) (s times the square root of 2). Example: A square has a perimeter of 10, and you need to know the length of the diagonal.s = 2.5, so d = 2.5 * sqrt(2).
      
   3. The 30^o - 60^o - 90^o right triangle: This is half of an equilateral triangle. The short leg, the one opposite the 30^o angle, is s, the hypotenuse is 2s, and the long leg, which is opposite the 60^o angle, is s * sqrt(3) (s times the square root of 3).
8. Number of diagonals in an s-sided polygon: I've seen so many different applications of this formula:
   s (s - 3) / 2
   where s is the number of sides of the polygon. A polygon having 45 sides has 45*(45-3)/2 = 945 diagonals.
9. Fraction, decimal, percent equivalencies: You must know these backward, forward, and upside down. The halves, thirds, fourths, fifths, sixths, sevenths, (yes, sevenths!), eighths, ninths, tenths, (so hard, he?), elevenths, twentieths, twenty-fifths, fiftieths. It also helps to know the twelfths, fifteenths, and sixteenths. You should, for example, be able to recognize, instantly and without hesitation, that 83 1/3% is 5/6, and that 9/11 is 81 9/11%.
10. Space diagonal of a cube:
    s * sqrt(3)
    where s is the edge of the cube. This is an application of the Pythagorean Theorem: See Section Vll(B) above. Figure out why this is so. Don't expect me to do it for you.
11. Area and Volume:
    
    1. Area of a square, given the side: A = s ²
    2. Area of a square, given diagonal: A = d ²/2
    3. Area of a rhombus, given diagonals: A = (d₁ d₂)/2
       (B and C are closely related. How?)
    4. Area of triangle: A = (bh) / 2
    5. Area of circle: A =  r ²
    6. Area of trapezoid: A = 1/2 h (b₁ + b₂)
    7. Volume of cylinder and prism: V = B h
    8. Volume of cone and pyramid: V = 1/3 (B h)
    9. Volume of a sphere: V = 4/3  r ³
    10. Surface area of a sphere: A = 4  r ²
12. I also expect you to know the following procedures:
    
1. Scientific notation, both multiplying and dividing numbers written in this form. All you do is apply the rules you've learned about exponents.
2. Turning a repeating decimal into a simple fraction. You see this almost every week; isn't it time to learn the shortcut for this, once and for all?
3. Turning a fractional percent into a simple fraction. Example: 20 5/6% = 5/24
4. Setting up probability problems. This is usually plain, simple reading. Know the terms "with replacement"; "without replacement", "at least one".
5. Be able to generate Pascal's Triangle on the spot. There are so many applications of this in combinations and probability.
6. Can you think of any more? I can. You should.

After you are done: Take the Quizlet here or make your own study guide using this website.
