Math: Human Discovery or Human Invention? So just what, in essence, is this thing called math? In developing these numbers and systems of numbers, did we discover the hidden coding of the universe? Is mathematics, in the words of Galileo, the language of God? Are we teaching math all wrong? By Carol Lloyd As sure as one plus one equals two, it happens year after year. Kids who have been bringing home A's in chemistry and acing AP Calculus arrive at college with visions of STEM careers dancing in their heads. Then they hit an invisible, but very painful, wall. A brief history of melancholy - Courtney Stephens Robert Burton attempted to gather the totality of human thinking on sadness and melancholy in his 1621 book The Anatomy of Melancholy.

CK-12 Launches a New Collection of Elementary School Math Resources CK-12 has long offered tutorials and practice exercises for middle school and high school science and math students. Today, CK-12 unveiled a new collection for resources for elementary school mathematics. The collection is organized by grade level (grades 1 through 5) and skill. The resources are a mix of videos and online practice exercises. While the CK-12 elementary school mathematics collection offers a lot of skills sections (addition, subtraction, multiplication, division, clock reading, measurement) each section appears to be fairly limited in its offerings. I checked five skill sections, one in each grade, and each was limited to one video and one exercise.
A Problem with a Word Problem Lynne Zolli, a colleague with whom I’ve worked on different projects for many years, told me about one of her third-grade student’s complaints about this test item: There are 40 chairs and 10 tables. If each table has the same number of chairs, how many chairs will there be at each table?

Oceanographer (and TED Prize winner) Sylvia Earle (TED Talk: My wish: Protect our oceans) has spent half a century campaigning to save the world’s seas. A new Netflix original documentary about her life’s work sheds light on the environmental impact of the commercial fishing industry and Earle’s crusade to create underwater “hope spots” through her organization, Mission Blue. After watching the film, it’s hard not to wonder: Are any fish still okay to eat?

They are merely individuals driven by the certainty that Lucia is the victim of a gross miscarriage of justice. # News:
