Man who had half of his brain removed

I received this story in an email and thought it was very encouraging and heart-warming! True story. I asked Scott for his permission to post it online.

In the beginning he is referencing this article of mine (I sent it to my list last year):

Enjoy... and SHARE. :)




Hello Maria,

I am just NOW ... today reading this email from about one year ago. I know terrible, but late than never, right.
Anyway, I wanted to write you and tell you that like Cameron, I had more than half of my brain removed in 1978. I had brain surgery for an AVM, arterial venus malformation. I had three surgeries total and nearly died. The doctors told my parents that if I lived I would be a vegetable. However, I defied them. I made it to the cover of the Children's Hospital of Sand Diego's December/January 1978/1979​ magazine. They called me the "Miracle Boy".


Anyhow, I just thought I'd share.

I have two master's degrees. I am a former teacher. I had to get out of teaching, due to my seizures. But upon my receiving of my first Master's degree, my father was still alive, and made it to my ceremony. He was so very proud. He told me that day that not only was I the first Blanchard in our family to ever receive an advanced degree, but he told me that I did it with less than half a brain!! I laughed, and he said, "NO really!"

He told me that my mother, who had died of cancer years before that, and my father had decided never to tell me about how much of my brain had been removed during the surgeries, because they never wanted me to use it as an excuse to say, "I can't do XXXX, because I only have less than half a brain..." or "I am not smart enough, since I don't have a full brain..." I am so very thankful for that, that they did not. But I just had to share this with you. 


Thanks, a lot.

Although I am not teaching in a classroom, I am teaching, in a way. I do tutor. I do help many friends who homeschool. And, for several years I have been a host father for boys from other countries coming to the U.S.A. for a year of schooling. I LOVE it. I am a single, never married 46-year old (on Sunday) guy, who is blessed beyond words, and am privileged enough to be able to share it with others.

Thanks, again, Maria.

Blessings for you and what you do. I do enjoy reading your emails. Sorry this one is so long in replying.

Scott

Will there be Math Mammoth Algebra 1?

I've had several people ask me if I'm planning to write algebra 1, algebra 2 and other high school math courses.

The answer is no. I'm planning to stop at pre-algebra. The main reason is, I've seen some fantastic high school math books other people have written -- people with lots of teaching experience etc. -- and I feel I could not surpass what those people have done. Especially when I don't have lots of experience teaching high school math to students.

You see, with elementary math, there exist numerous homeschool math curricula. I've seen most of them and I can tell many of them  are not written by someone who has a good background in math. To write a math text, it really helps to know what concepts the students encounter later on. But beyond that, math is strange in the fact that many of the FOUNDATIONS of math are only taught at university level. For example, the axiomatic foundation of real numbers; logic and the different proof techniques; the whole idea of how mathematical theories are constructed from axioms to theorems via proofs. Those things were very fascinating to me when I encountered them in university -- math had less to do with calculations and more to do with abstract ideas and thinking processes.

So... in order to guide students towards mathematical thinking in the early years, it helps a LOT to be familiar with the common techniques of proof, which people typically study in university (or college) level math courses.

Ok, what I'm getting at is this: most high school math books are written by people who've studied a lot of math in university. So... for the high school level, there already exist good math books written by people who truly know math and can write math texts and I feel there's no need for me to write anything, and that I could not write texts better than they.

I've tried to put together somewhat of a guide for high school math for people who ask me for advice. It's not 100% comprehensive -- I just don't have time to delve into all the textbooks that exist.

Also, it is not for everyone. I realize some students will just take practical math or something like that in high school. I just am a math lover -- not of the calculations but of the thinking processes and logical constructions -- so what I wrote on that page reflects that.

New pre-algebra topic books for Math Mammoth Blue Series

Three new books in the Blue Series! These books deal with some pre-algebra level topics.

Check out their free samples!


Math Mammoth Expressions & Equations workbook cover
Math Mammoth Expressions & Equations

This is a worktext covering the order of operations, equations, expressions, and simplifying expressions in several different ways in 6th-7th grade level.

The main principles are explained and practiced both with visual models and in abstract form, and the lessons contain varying practice problems that approach the concepts from various angles. We also touch on inequalities and graphing on a very introductory level. In order to make the learning of these concepts easier, the expressions and equations in this book do not involve negative numbers (as they typically do when studied in pre-algebra and algebra).

Sample pages (PDF)
Contents
Expressions
Writing and simplifying expressions 2: area
The distributive property
More equations



Math Mammoth Rational Numbers workbook cover
Math Mammoth Rational Numbers

In Math Mammoth Rational Numbers we study rational numbers, which are numbers that can be written as a ratio of two integers. All fractions and whole numbers are rational numbers, and so are percentages and decimals (except non-ending non-repeating decimals). Hopefully, students already know a lot about rational numbers and how to calculate with them. Our focus in this book is to extend that knowledge to negative fractions and negative decimals.

Sample pages (PDF)
Contents
Rational Numbers
Multiply & Divide Rational Numbers 1
Multiply & Divide Rational Numbers 2
Equations with Fractions



Math Mammoth Linear Equations workbook cover
Math Mammoth Linear Equations

Math Mammoth Linear Equations presents the student with the basics of solving linear equations, including equations that involve a variable on both sides and equations that require the usage of the distributive property to eliminate parentheses. We also briefly study inequalities and graphing. This book best suits pre-algebra or grades 7-8.

Sample pages (PDF)
Contents
Word Problems 1
Two-Step Equations
Growing Patterns
Variable on both sides
Graphing
Speed Time, and Distance

Lesson on Fibonacci numbers

Have you ever heard about the Fibonacci numbers and the Golden ratio?


A tiling that uses squares whose side lengths are successive Fibonacci numbers. Ask students to continue it! Image from Wikipedia.


Here's a lesson I just wrote about them:

Fibonacci numbers and the golden section – lesson for middle and high school students

If you like it, share it!

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. :)
