The Early math Math Mission (sometimes referred to as K-2nd Math Mission) was a set of skills on Khan Academy. This mission introduced and applied natural numbers as counting numbers, practiced basic operations on natural numbers, and introduced some early geometry concepts such as measurement and common geometric shapes. Due to the June update and transitioning of Khan Academy, missions have been removed forever. They have now been replaced with course Mastery.
