The

**6th Grade (U.S.) Math Mission**is a set of skills on Khan Academy. This mission consists of foundational material and then proceeds into ratios, operations on positive rational numbers, concepts with negative numbers, Least Common Multiple (LCM) and Greatest Common Factor (GCF), the coordinate plane, area formulas, familiarity with variables and expressions and finally data summary and display.## Mission Specifics
