By the 6th grade, you're becoming a sophisticated mathemagician. You'll be able to add, subtract, multiply, and divide any non-negative numbers (including decimals and fractions) that any grumpy ogre throws at you. Mind-blowing ideas like exponents (you saw these briefly in the 5th grade), ratios, percents, negative numbers, and variable expressions will start being in your comfort zone. Most importantly, the algebraic side of mathematics is a whole new kind of fun! And if that is not enough, we are going to continue with our understanding of ideas like the coordinate plane (from 5th grade) and area while beginning to derive meaning from data!

## Least common multiple

Life is good, but it can always get better. Just imagine being able to find the smallest number that is a multiple of two other numbers! It's called the LCM or Least Common Multiple. Other than making your life more fulfilling, lcm will allow you to do incredible things like adding fractions. Common Core Standard: 6.NS.B.4

## Greatest common factor

You know how to find factors of a number, but what about factors that are common to two numbers? Even better, imagine the largest factors that are common to two numbers. These are called the greatest common factors (GCF) or sometimes greatest common divisors (GCD). Yay, acronyms! Too exciting! Common Core Standard: 6.NS.B.4
