Matematicas Visuales In MatematicasVisuales you will find visual expositions of mathematical concepts. MatematicasVisuales intends to complement the work initiated by artiludios, a site with games, puzzles and mathematical curiosities. Reading Miguel de Guzmán I found a demonstration of the line of Simpson and the Steiner Deltoid.

Pythagoras’ Comma In Problem 1 (Six Notes all Nice Ratios ) we explored a six point scale : shortest length to double that, with four lengths in between. In this problem the scale now has 12 points : shortest to double, with ten lengths in between. We are going to look for a closed and complete scale. making middle school math fun Engaging Tomorrow's Workforce Technology leadership is a source of long-term security. Raytheon is pursuing a multilevel strategy to ensure that our customers, our company and new generations of professionals have the leading-edge skills they need to thrive in today's fast changing world. Over the last decade, jobs in science, technology, engineering and math have grown at three times the rate of other jobs, according to the U.S. Department of Commerce. To inspire and equip students to succeed in these STEM positions worldwide, we provide strong support at all levels of education. Our goal: to build the next generation workforce.

Fun Kids Online Math Games "Sheppard offers everything from early math to pre-algebra. The lessons include interactive activities to practice concepts. Students can shoot fruit, pop balloons, and even play math man (the math version of pac man!). Fractions, place value, money, and basic operations are some of the areas that are covered. Check it out at " --Shannon Jakeman , "Online math games, like the ones that you'll find for free at Sheppard Software, provide a valuable opportunity for children to learn a great deal while they're having fun. Pat'sBlog: Why M for Slope Over the many years I taught I developed a keen interest in the origin and use of the symbols and terminology of math. When the internet came around I jumped in pretty early with a web page on Mathwords, contributing on the Dr Math and Teacher to Teacher support Math Forum, and for several years, this blog. Over that time there are few questions that come up more often than the reason for the letter m as the symbol for slope in the standard American (and it does seem to be mostly American) linear slope intercept equation form, y = mx + b. Almost no one seems to ask about the b, which is even more curious to me.

Free Mathematics Resources OnLine What about free graphing and algebra on your mobile phone? XCalc is a free Java Applet which offers a graphing calculator for any mobile phone which runs Java (which is nearly all of them now!) Think about the possibilities for classes that do not yet have access to graphing calculators! While limited (it does not yet have a trace facility) it DOES offer 2d and 3d graphing which is quite fast and powerful. Well worth a play!

Regulatory cards Why do maths students need self-regulation? Alan Schoenfeld in a seminal chapter from 1987 (What’s all the fuss about metacognition?) discussed his observations of how undergraduate students solved problems. More than half, when faced with a non-standard problem outside a familiar context, followed the path illustrated in diagram 1. In this case, a pair of students read the problem, made a correct conjecture, but then got bogged down in calculations and ran out of time, even though they had the required knowledge to solve the problem.

Cyberchase . FREE Lucky Star Game Show Application for SMART Board Designed for grades 3-5, the CYBERCHASE Lucky Star game show challenges kids to compete for top scores while building important math skills. This easy-to-install application engages students using the hugely popular characters from CYBERCHASE and offers the following features: Motivational & Replayable Learning: 150 fun questions combine a mix of age-appropriate math and problem-solving to help students strengthen their skills in algebraic thinking, number and operations, geometry, measurement, and more. Think Pad: Students can represent their thinking as they solve problems on the Think Pad, a blank dropdown area that lets them use the SMART Board interactive whiteboard's pens to write directly into the game. Math Manipulatives: Lucky Star takes advantage of the SMART Board's touch screen interactivity by encouraging kids to manipulate objects on screen with their hands.
