Orders of Magnitude

Thinking in Quantity: Level 6 - Orders of Magnitude
In this video Paul Andersen shows conceptual thinking in a mini-lesson on orders of magnitude. Two examples are included in the video and two additional examples are included in the linked thinking slides.

TERMS
Scale models - a representation that has been reduced or enlarged to a specific scale
Orders of magnitude - is an approximation of the logarithm of a value relative to a reference value, usually ten

This progression is based on the Crosscutting Concept elements from the NRC document A Framework for K-12 Science Education. “Students use orders of magnitude to understand how a model at one scale relates to a model at another scale.”
