The Elementary Math Maniac: A Fun Free Tool for Practicing Counting
If you have ever been in a K-2 math class, you know how important counting is. I recently posted some of my favorite you tube videos for practicing counting, my favorite counting books, and have written a seven part series on estimating and counting routines that I use in my classroom. I have also written about interventions I use to help kids learn to count.

"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!).
Webtools: No Registration Needed for Students
Welcome to my list of webtools that don’t require student registration. This started off as a simple curation for myself and has ballooned into something that I never thought would get this big. And it is still growing. I started added comments to each link, but that is taking a long time to complete.

Gravitational waves – your questions answered
The final piece of Einstein's general theory of relativity, which has stubbornly evaded detection since his predictions a century ago, has been detected. Scientists announced today at a press conference they’ve successfully picked up gravitational waves, formed during the cataclysmic collision and fusion of two mammoth black holes 1.3 billion light-years away. Not only does this confirm Einstein’s predictions, it gives astronomers a new method of “seeing” the Universe. Nailing down gravitational waves – ripples through the fabric of space-time – has not been an easy task. Even Einstein was pessimistic about finding the miniscule vibrations. Indeed, in 2014 the astrophysics world was elated with the announcement that the Background Imaging of Cosmic Extragalactic Polarisation (BICEP2) telescope at the South Pole had picked up faint echoes of the Big Bang, only to have those hopes dashed when the signal turned out to be dust in our own galaxy.

What Does E=mc2 Truly Mean?
What does E=mc2, the most famous equation in history, mean? (Image Credit: PBS Space Time) Albert Einstein remains one of the greatest minds in history. His contributions to the fields of cosmology, physics and mathematics are unquantifiable, but arguably, the most important works were his theories of general and special relativity. Ultimately, they shed light on the intimate workings of the universe—from the nature gravity itself, to the outermost edges of black holes.

I wish I knew the best way to explain my Math Stations. I've said it many times, I like it simple, clear and meaningful. So ... in a nutshell... here is how I run my math stations in my 2nd grade class. Each month I cover 12 CC standards. 4 from each domain:

Interactive Fraction Wall explore Fractions Percentages and Decimals
Fraction walls are a great way to teach about fractions and in particular equivalent fractions. In a fraction wall each row or layer of the wall represents one whole number. The layers are divided into a number of bricks and hence each brick represents a fraction whose denominator is equal to the number of bricks in that layer. Each brick can be turned on or off by clicking it. This wall also allows the display of decimal and percentage values. To the right of the wall are boxes which can be hidden, the value of each box is fraction of the wall that has been turned on.
14 Virtual Tools: Favorite Math Apps
More and more classrooms are gaining access to technology that can be used with students. Whether you’re modeling a lesson, creating stations, or working in a one-to-one classroom, virtual tools can promote student engagement while increasing academic success. Here are some apps for iPads — along with a few other tips — that can transform your daily lessons and are definitely worth checking out! Base Ten Blocks
