An introduction to logarithms by using fact families and related facts. If "a to the power of b equals c," then "the bth root of c equals a," and "log, base a of c equals b."
This lesson includes suggestions for opening discussion: "What is logarithmic thinking?" Logarithms are presented as related to powers and roots, and students practice using fact triangles to write related facts.
A student activity is included that involves rolling fact triangle 'dice' and using them to determine related facts for powers, roots, and logs.
Teacher instructions, notes, activity pages, and solutions are all included.
