9 Strategies for Motivating Students in Mathematics
Motivating students to be (enthusiastically) receptive is one of the most important aspects of mathematics instruction and a critical aspect of the Common Core State Standards. Effective teachers should focus attention on the less interested students as well as the motivated ones. Presented in this blog post are nine techniques, based on intrinsic and extrinsic motivation, which can be used to motivate secondary school students in mathematics. Extrinsic and Intrinsic Motivation Extrinsic motivation involves rewards that occur outside the learner's control.

Big Data, Data Mining, Predictive Analytics, Statistics, StatSoft Electronic Textbook
This free ebook has been provided as a public service since 1995. Statistics: Methods and Applications textbook offers training in the understanding and application of statistics and data mining. It covers a wide variety of applications, including laboratory research (biomedical, agricultural, etc.), business statistics, credit scoring, forecasting, social science statistics and survey research, data mining, engineering and quality control applications, and many others. The Textbook begins with an overview of the relevant elementary (pivotal) concepts and continues with a more in depth exploration of specific areas of statistics, organized by "modules", representing classes of analytic techniques. A glossary of statistical terms and a list of references for further study are included.

Fun with the Impossible Penrose Triangle
I found this delightful animation today: The ball is traveling around a shape that can’t exist in our real world: the Penrose triangle. This illusion is the basis for some cool art, like Escher’s Waterfall. And I’m using it in my Math You Can Play books as a design on the back of my playing cards:

What is Chaos Theory? : FractalFoundation.org
Chaos is the science of surprises, of the nonlinear and the unpredictable. It teaches us to expect the unexpected. While most traditional science deals with supposedly predictable phenomena like gravity, electricity, or chemical reactions, Chaos Theory deals with nonlinear things that are effectively impossible to predict or control, like turbulence, weather, the stock market, our brain states, and so on. These phenomena are often described by fractal mathematics, which captures the infinite complexity of nature. Many natural objects exhibit fractal properties, including landscapes, clouds, trees, organs, rivers etc, and many of the systems in which we live exhibit complex, chaotic behavior. Recognizing the chaotic, fractal nature of our world can give us new insight, power, and wisdom.

LUMA.fi: Viikon matikkatehtävä 16/2015: Mancala
Viimeinen viikon matikkatehtävä eli matikkapeli Mancala on kylvöpeli, jossa tarkoituksena on kerätä mahdollisimman monta pelimerkkiä omaan kotipesään ja tyhjentää vastustajan kolot. Mancala on kaksinpeli, joka aloitetaan kylvämällä jokaiseen koloon kolme pelimerkkiä. Kummallakin pelaajalla on laudalla oma puoli ja kotipesä. Kumpikin pelaaja valitsee vuorollaan jonkin oman puolensa kolon ja kylvää kolossa olleet pelimerkit seuraaviin koloihin. Kun jomman kumman pelaajan kolot ovat tyhjiä, peli päättyy. Pelimerkkejä kannattaa aina mahdollisuuden tullen kylvää omaan kotipesäänsä, sillä pelin loppuessa voittajaksi julistetaan se, kummalla on enemmän merkkejä omassa kotipesässään.

Citizen Maths: A Free Course to Build Adult Math Skills
Do you want to improve your grasp of math so you can help your children understand their homework? Did math pass you by at school, or have your skills grown rusty over the years? Do you find it hard to apply what you know to the real-life problems you need to solve now—like using spreadsheets, interpreting data, or assessing risks? If so, then the free, online, work-at-your-own-pace Citizen Maths course may be just what you need.
Hi and welcome to my 30th gems post. This is where I share some of the best teaching ideas I've seen on Twitter. 1.
Paper Toys: Flextangles
Today’s paper toys, Flextangles, are the fourth project in our collaborative series STEAM POWER: Empowering kids to explore the world through creative projects. Today’s topic is COMPUTE! Since I recently answered this question wrong, I decided it might be good idea for me to limit my math based project to something I’m good at: geometry.

Quadratic Functions
How can you tell, by LOOKING at a quadratic function, if the vertex is going to be considered 'minimum' or 'maximum' and what exactly is the difference between the two vocabulary words? Well, if you stop and thought about the two words, you just might be able to come up with a logical conclusion. Since a parabola is a U-shape, let's take a look at what this shape looks like in a drawing again and see if you can come up with a conclusion all on your own. Okay, now think of the two words: minimum and maximum. What do they mean?
