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. Instead of teaching fact families by rote, Singapore illustrates fact families using number bonds. 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. Number Bond Flashcards Teaching Algebraic Thinking

Algebra Meltdown Game Goals In this maths game you have been recruited by Lissaman Industries to assist in one of their super-secret, ultra-dangerous research projects. As the new controller of the mighty Nuclear Generator, your job is to serve scientists waiting at the Generator's outlets. Each scientist needs a certain atom, which you create by solving linear equations and then guiding 'raw' atoms through the Generator's maze of machines and tubes. Be quick: the scientists are impatient to continue their work. Take too long to serve them and they grow annoyed and eventually storm off; let this happen too many times and you will be fired! The ultimate aim of the project is to construct a monstrous mega-machine known only as 'The Device'. How To Play Algebra Meltdown's action takes place across multiple level or 'shifts', each featuring a unique Nuclear Generator layout. Across the top of the screen is a rack dispensing 'raw atoms' between values -9 and +9 (B). Game Controls Generator Components Intake Funnel

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. This is one of the most important lessons on my site so make sure that you fully understand it and feel fully comfortable with it. 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.

XtraMath 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

Radical Math 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? 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: Negatives in PAIRS are POSITIVE; NOT in pairs, they're NEGATIVE.

cell phone project Project K-Nect is designed to create a supplemental resource for secondary at-risk students to focus on increasing their math skills through a common and popular technology – mobile smartphones. Ninth graders in several public schools in the State of North Carolina received smartphones to access supplemental math content aligned with their teachers’ lesson plans and course objectives. Students communicate and collaborate with each other and access tutors outside of the school day to help them master math skills and knowledge. The smartphones and service are free of charge to the students and their schools due to a grant provided by Qualcomm, as part of its Wireless Reach™ initiative.

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. Please e-mail and tell me! 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.
