Other Thoughts
- Many experiences are needed to build understanding of proportional reasoning.
The fact that many aspects of our world operate according to proportional rules
makes this reasoning essential in the interpretation of real world phenomenon.
Thus, proportionality serves as a bridge to the more abstract relationships addressed in the formal study of algebra.
