Simply send an email to the address prize [at] mathmammoth [dot] com between now and midnight Pacific time, Thursday, October 16, 2014. I will choose the winners after that time using a random number generator, and email them.
You do not have to include anything in specific -- if you are chosen as a winner, I will contact you for any information I will need at that point.
People from outside the USA are also welcome to take part! We can ship CDs worldwide, or you can receive the Math Mammoth materials as a download.
You might ask, "Should our children or students even learn about Fibonacci numbers or the golden ratio?"
True, they aren't any standard fare in math books. However, I feel that yes, students should know about them. I think it's important that our young people learn a few math topics that show how MATH appears in NATURE. You could even call it "MATH APPRECIATION".
Children study "art appreciation" so they can appreciate human works of art. Shouldn't we also appreciate the "artworks" in nature, such as flower petals and seed heads? And, once you understand a little bit about the math behind them, you will appreciate them even more. :)
Here's an interesting story problem that I received in an email!
A farmer died leaving his 17 horses to his three sons. When his sons opened up the will it read:

My eldest son should get 1/2 (half) of total horses;
My middle son should be given 1/3rd (one-third) of the total horses;
My youngest son should be given 1/9th (one-ninth) of the total horses.
As it's impossible to divide 17 into half or 17 by 3 or 17 by 9, the three sons started to fight with each other. So, they decided to go to a farmer friend who they considered quite smart, to see if he could work it out for them.
The farmer friend read the will patiently, after giving due thought, he brought one of his own horses over and added it to the 17. That increased the total to 18 horses.
Now, he divided the horses according to their fathers will.
Half of 18 = 9. So he gave the eldest son 9 horses.
1/3rd of 18 = 6. So he gave the middle son 6 horses.
1/9th of 18 = 2. So he gave the youngest son 2 horses.
Now add up how many horses they have:
Eldest son 9
Middle son 6
Youngest son 2
TOTAL IS 17
Now this leaves one horse over, so the farmer friend takes his horse back to his farm.
The attitude of negotiation and problem solving is to find the 18th horse i.e. the common ground. Once a person is able to find the 18th horse the issue is resolved. It is difficult at times. However, to reach a solution, the first step is to believe that there is a solution. If we think that there is no solution, we won't be able to reach any!
You might already know that the placement tests on my site work equally well as generic math assessment tests.
I also evaluate the test results for free.
Now you can see an example of one student's test results and my evaluation here.
Many students need to take two or even more tests in order to get a full picture of the gaps they have in their skills and knowledge. That was the case with this student also: she actually took three tests, grade 6, 5, and 4. I posted two of the tests and my evaluation at MathMammoth.com site. I hope it's helpful!
Number talks are short discussions among a teacher and students about how to solve a particular mental math problem. The focus is not on the correct answer, but on all the possible methods of finding the answer.
Each student has a chance to explain their method, and everyone else will learn from other people's methods!
To start a number talk, the teacher gives the students a SHORT math problem to solve — but the students are not allowed to use a calculator or paper & pencil. The idea is to solve it in one's head!
For example, you could ask students to solve 5 × 18 using mental math.

Also, grade 7-A is not yet available on any of the bundle products, CDs (such as the Light Blue series CD or All Inclusive CD) nor as printed copies. You can expect it to be included in the downloadabe bundles (Light Blue series, All Inclusive, Everything Bundle) by the beginning of September and on CDs after the first week of September.
I just know there are folks "chomping at the bit" to get it so I'm sending this notice now — as early as possible — when only the download of 7-A is available.
I think some of you will enjoy reading the story of Maryam Mirzakhani, an iranian Mathematician, and a woman, who just recently won the most prestigious award in the world of mathematics: the Fields Medal.
