An interactive lesson on Input/Output for Upper Elementary or Middle School Teachers. The lesson has 4 separate functions but it has directions how to include your own by making additional pages. There are 3 levels for each function. The first level is the interactive part and students are trying to determine the pattern or rule as they view 3 examples. The second level is more abstract with writing the numbers in the input/output chart to follow the rule.

The third level is the coordinate plane where the points are plotted and the students see if there is a pattern with the points on the graph.

A student handout is provided for all students to follow with the second and third level.
