Khan Academy’s math program is designed to help children and young adults learn and practice a particular set of math skills. These skills map to school curricula like the US Common Core, so that when students learn something on the site, it translates to success in the classroom. But Khan Academy can also help adults review the fundamental skills necessary to learn more advanced math. The idea is to fill in “swiss cheese gaps” in knowledge that often accumulate when learning math in school. These gaps can slow down further learning, since math success in later courses depends on knowing the skills taught in previous courses.

This week, I’ll go over the topics available on Khan Academy. Next week, I’ll look at how they relate to discrete math topics.
