### What is going on?

**High Score Reset:**

The high score boards will be cleared on February 14th. Thank you to all of the current placeholders and good luck to the next set.

**Uses for Divisibility Rules:**

Why do we practice divisibility rules? They are useful when reducing fractions. They help in determining prime factorization, greatest common factor and the least common multiple.

**Astronomy and Space:**

Are you interested in astronomy and space? Check out the National Science Foundation. They examine research on fundamental questions. What is the universe made of, and how does it work? Are we alone? Learn about the Big Bang, dark matter, superstrings, and Einstein's general theory of relativity. They have great pictures and some interactive content.
