The Thirty Greatest Mathematicians Click for a discussion of certain omissions. Please send me e-mail if you believe there's a major flaw in my rankings (or an error in any of the biographies). Obviously the relative ranks of, say Fibonacci and Ramanujan, will never satisfy everyone since the reasons for their "greatness" are different. I'm sure I've overlooked great mathematicians who obviously belong on this list. Following are the top mathematicians in chronological (birth-year) order. Earliest mathematicians Little is known of the earliest mathematics, but the famous Ishango Bone from Early Stone-Age Africa has tally marks suggesting arithmetic. Early Vedic mathematicians The greatest mathematics before the Golden Age of Greece was in India's early Vedic (Hindu) civilization. Top Thales of Miletus (ca 624 - 546 BC) Greek domain Thales was the Chief of the "Seven Sages" of ancient Greece, and has been called the "Father of Science," the "Founder of Abstract Geometry," and the "First Philosopher."

Math and English: free printable math materials in English for mative students and ESL math students. BEAM : : BE A Mathematician LCM and GCF Foldable | tothesquareinch With my 6th and 7th grade students, I find that when I teach Least Common Multiple and Greatest Common Factor, the kids “get it” so quickly in isolation. When they are taking a test or quiz, undoubtably at least 1/2 the class confuses the two. Before I gave my 7th graders a test last week, we made these 2 door foldables. Each table was given a set of numbers. They had to find the GCF and LCM of the sets. Students then shared with the other groups in the class. Click on the picture below for the GCF and LCM foldable. Don’t teach GCF and LCM? Enjoy! ☼Kate Like this: Like Loading...

Math and Inquiry: The Importance of Letting Students Stumble A Science Leadership Academy sophomore puts the finishing touches on a geometry project during her lunch period. For subjects like math and foreign language, which are traditionally taught in a linear and highly structured context, using more open-ended inquiry-based models can be challenging. Teachers of these subjects may find it hard to break out of linear teaching style because the assumption is that students can’t move to more complicated skills before mastering basic ones. But inquiry learning is based on the premise that, with a little bit of structure and guidance, teachers can support students to ask questions that lead them to learn those same important skills — in ways that are meaningful to them. This model, however, can be especially hard to follow in public school classrooms tied to pre-set curricula. “As much as we can say it’s okay for students to fail within the class, if they don’t pass the test at the end of the year, it’s suddenly not okay.” Related

Grid Paper PDFs Downloadable and very printable, I find these PDFs extremely useful. Graph Paper Quick Picks Now set to: 8 1/2 x 11 Paper. Now set to: A4 Paper, Ruled in Millimeters. Custom Graph Papers Need more specific stuff? Tip number one! Though I do return the correct header for a PDF, sometimes Explorer gets confused when downloading... Tip number two! Some people may need to turn off the option in Adobe's Acrobat reader "shrink to fit" which may resize the grid slightly to fit your printer's printable area. Tip number three! If you want the hexes aligned with the other edge of the paper, just make your paper size "11 x 8.5" and print the result in landscape mode!

An Intuitive Guide To Exponential Functions & e e has always bothered me — not the letter, but the mathematical constant. What does it really mean? The mathematical constant e is the base of the natural logarithm. And when you look up natural logarithm you get: The natural logarithm, formerly known as the hyperbolic logarithm, is the logarithm to the base e, where e is an irrational constant approximately equal to 2.718281828459. Nice circular reference there. I’m not picking on Wikipedia — many math explanations are dry and formal in their quest for rigor. No more! e is NOT Just a Number Describing e as “a constant approximately 2.71828…” is like calling pi “an irrational number, approximately equal to 3.1415…”. Pi is the ratio between circumference and diameter shared by all circles. e shows up whenever systems grow exponentially and continuously: population, radioactive decay, interest calculations, and more. Understanding Exponential Growth Let start by looking at a basic system that doubles after an amount of time. A Closer Look Mr.
