  Learning to use math in science is a non-trivial task. It involves many
different skills (not usually taught in a math class) that help blend physical
knowledge with mathematical symbology. One of these is the idea of
quantification: that physical quantities can be assigned specific numbers. A
second is to develop an intuition for scale. One way to help students develop
these skills is to teach estimation: the ability to consider a physical
situation and put reasonable approximate numbers to it
