#### Powers of Ten - Number Sense

Students (and adults) have a difficult time trying to grasp very large (and very small) numbers. This activity uses an interesting context (astronomical objects0 to stimulate their interest in modeling enormous distances in a way that can help them understand relative distances. Students naturally arrive at the need for a different kind of number scale than linear and arrive at a "power of ten" (logarithmic) scale. The lesson includes an extension for advanced students ready to begin to investigate logarithms.
