I noticed this little guy on a wall as I was walking along the other day, and thought about the difference math education makes in perceiving the snail.
A snail builds its shell at a rate proportional to its size (see Nature's Numbers), resulting in exponential growth. An understanding of the exponential function is so important in today's world (see examples of its application) that I was inspired to make a poster. Feel free to print it for your classroom, and let me know what you think!
