Read the excerpt from the Standards Decoded document. This is a description of all the standards in the Ratio and Proportion domain.
Respond to the following questions:
1. In a “traditional” curriculum, the topic of proportion was often limited to the “cross-multiply and divide” algorithm. What are three ways in which the CCSS approach to developing proportional reasoning differs from the more “traditional” algorithmic approach? In what ways would this approach to teaching proportional reasoning benefit students (e.g., in terms of connections to future mathematics learning)?
2. The Standards Decoded document is one resource that we will examine in the course that provides additional information for understanding or “decoding” the standards. Describe one idea from this document that was important to your own “decoding” of the RP domain. Why was this idea significant?
