Thinking in Proportion: Level 5 - Proportional Relationships
In this video Paul Andersen shows conceptual thinking in a mini-lesson on proportional relationships. Two examples are included in the video and two additional examples are included in the linked thinking slides.
TERMS
Quantities - the amount (or number) of a thing
Proportional relationship - relation of one dataset to another dataset
Directly - two quantities are proportional to each other (linear proportion)
Inversely - as one quantity increases the other decreases. Product of values is constant.
Magnitude - the size, scale or importance of properties and processes
This progression is based on the Crosscutting Concept elements from the NRC document A Framework for K-12 Science Education. “Proportional relationships (e.g. speed as the ratio of distance traveled to time taken) among different types of quantities provide information about the magnitude of properties and processes.”
