The Secret to Teaching Math Facts: Number Bonds Below you will see why I think teaching math basics with number bonds is the best way for your homeschoolers to learn math. Over our last four years of homeschooling, I have used several different math curricula. Some I liked better the others, but they all had their own strengths and weaknesses. One of the strengths of one particular curriculum we use, Singapore Math, is their method of teaching basic math facts. Now, I realize this is just my unprofessional opinion, but as a self-professed math geek, I truly believe number bonds are (likely) the best ways to teach math facts. Why? They're simple. How Number Bonds Work If you're not familiar with what number bonds are, allow me to illustrate. As in the example for addition on the left, the student is taught to recognize that the number 7 is made of 3 and 4. If you'd like to teach your children number bonds, you can download my Number Bond Chart and Worksheet set here. Number Bond Flashcards Teaching Algebraic Thinking
The Brain—Information about the Brain 1 Introduction “I think, therefore I am.” —René Descartes, 17th-century philosopher Few of us question the crucial importance of the brain. The brain makes up only 2 percent of our body weight, but it consumes 20 percent of the oxygen we breathe and 20 percent of the energy we consume. Scientists have worked for many years to unravel the complex workings of the brain. Despite these and other significant advances in the field of brain research, most of the processes responsible for the integrated functioning of billions of brain cells remain a mystery. An essential aspect of any scientific research is communicating results to the public in a way that is easily understood. To correctly interpret the information transmitted through these venues, we need a better understanding of basic concepts related to the brain. 2 Myths and Realities about the Brain As a result of the misinformation presented by various media, many people maintain misconceptions about the brain and brain function.
Program Plan: The Social Media Center of Excellence Definition: “Center of Excellence” This is a program deployed by companies trending in the advanced levels of social business maturity. The Social Media Center of Excellence (CoE) is a centralized program that provides resources, training, and strategy to a variety of business units that are deploying social media in order to reduce costs, increase efficiency, and provide standardization. This team is often run by the Corporate Social Strategist, who’s the business stakeholder and program champion. The Social Media Center of Excellence has Four Major Duties: Planning, Resources, Processes and Vendor Selection and Management Data: Companies Desire To Organize Social Media Adoption by corporations only continues to rise.

Adding Signed Numbers - Lesson 101 Video Adding Signed Numbers - Lesson 101 Hi, I’m Larry. This is the video from Lesson 101 on my website, adding signed numbers. I you have difficulty understanding this lesson you will have trouble with all the materials that follows because it builds up on this lesson especially when we get to Algebra we’re going to be using the skill again and again, so make sure that you don’t have any difficulty with it whatsoever. Up until now I’ve been working with adding positive numbers and we haven’t any trouble with that. Now, very often students say something like, “Wow! Now, I like to think of negative numbers as a debts or how much money I owe, so if I say negative three I’ll think of that as I owe $3.00. For this example I’d like to add 3 + -5. Here’s how I like to teach you. Okay, so the situation is I have $3.00 but I owe you $5.00. I still owe you $2.00 and the way I will show that is by writing a -2 the negative meaning I owe you money, I still owe you money.

Integer Number Line In this lesson,we will look at integers and the number line. Related Topics: More Lessons on Integers Integer Worksheets Integer Games Integers Integers consist of negative integers, zero and positive integers. Example: 0 is an integer but is neither positive nor negative. Negative numbers have a ‘–’ sign before them. Example: –3 is read as “negative three” +6 or 6 is read as “positive six” or “six” Opposite of a Number The opposite of a number is the number with the sign changed. The opposite of 4 is –4 The opposite of –6 is 6 Since 0 is neither positive nor negative, the opposite of 0 is also 0. Number Line Integers can be represented on the number line. An integer on the horizontal number line is greater than the number on its left and less than the number on its right. Example: –1 is greater than –2 and less than 0. We can also write it as –1 > –2 and –1 < 0. Recall that “>” means greater than and “<” means less than. On the number line, moving to the right is positive. OML Search
Cranial Nerves Can't remember the names of the cranial nerves? Here is a handy-dandy mnemonic for you: On Old Olympus Towering Top AFamous Vocal German Viewed Some Hops. The bold letters stand for: olfactory, optic, oculomotor, trochlear, trigeminal, abducens, facial, vestibulocochlear, glossopharyngeal, vagus, spinal accessory, hypoglossal. Still can't remember the cranial nerves? s Math Resources - Integers: Operations with Signed Numbers Have you ever been to a party like this? Everyone is happy and having a good time (they are ALL POSITIVE). Suddenly, who should appear but the GROUCH (ONE NEGATIVE)! The grouch goes around complaining to everyone about the food, the music, the room temperature, the other people.... What happens to the party? Everyone feels a lot less happy... the party may be doomed!! But wait... is that another guest arriving? What if another grouch (A SECOND NEGATIVE) appears? Now that the two grouches are together the rest of the people (who were really positive all along) become happy once again. The moral of the story is that (at least in math, when multiplying or dividing) the number of positives don't matter, but watch out for those negatives!! To determine whether the outcome will be positive or negative, count the number of negatives: If there are an even number of negatives -and you can put them in pairs- the answer will be positive, if not... it'll be negative:
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. 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."
