How math.wiki lines up with your standards
Pick your standards and a course. Every standard is matched to the lessons that teach it, and every lesson links to its full text. Where we teach something in a different grade, we show where and say why. Common Core does not divide high school into courses, so each high school course lists the standards its own lessons teach.
Where our order differs, and why
Every math.wiki lesson comes after the lessons it depends on; the map draws those lines. Where that order differs from a standards document, it is on purpose:
- Skills are taught where they first appear, then retaught. Long division reaches fluency in Grade 5, where students learn it, and is retaught in Math 6, rather than waiting a year to finish it.
- One idea, one lesson, built on. Composing shapes, adding ten and measuring length each live in one lesson that the next grade reviews and extends, instead of two lessons that repeat each other.
- Statistics gets sustained time. Algebra 1 ends with a full statistics unit and Statistics is its own course, rather than spreading the topic thin.
- Conditional probability sits in Algebra 2 and Statistics, not Geometry, because it builds on counting and fractions, not on figures.
- Trigonometric functions start in Precalculus, with right-triangle trigonometry in Geometry. A rushed unit-circle unit in Algebra 2 usually has to be retaught.
- Proof is a thread from Grade 3, because why it works is the part of mathematics students most often never see.
