The

**7th grade (U.S.) Math Mission**is a set of skills on Khan Academy. This mission consists of foundational material and then proceeds into intensify students' previous knowledge of operations with numbers, familiarizing them with variable usage, and increases their knowledge in geometry and statistics, including some more advanced probability ideas.## Mission Specifics
