The

**4th Grade (U.S.) Math Mission**is a set of skills on Khan Academy. This mission consists of continued practice of operations on different types of numbers, introduction of remainder when dividing, relationships between decimals and fractions, practice with applications and word problems and continued expansion of basic geometric and statistical concepts.## Mission Specifics
