Math Throughlines

The big mathematical ideas that keep showing up.

Mathematics is not a collection of disconnected skills. They all build on one another, and ideas learned in first grade connect to those introduced in calculus.

Current working throughlines:

  1. Quantity and magnitude
  2. Unitizing
  3. Equivalence
  4. Structure
  5. Relationships between quantities
  6. Representation
  7. Scale & Proportionality
  8. Change and covariation
  9. Generalization
  10. Invariance
  11. Making and interpreting predictions

Keep in mind that this framework is evolving as more research is done and continues to be tested.
