Previously Published Data

1.) Students will draw, measure, and record the perimeter, area, and volume of numerous polygons. 


2.) Students will make and record their conjectures about the effects of changing one or more of the dimensions of the (above) polygons. 
3.) Students will then change one or more of the dimensions of each polygon (above) and confirm or refute their conjectures about the effect of the changes on the perimeter, area, and volume.


Previously Published Data

1.) Students will write an explanation of how changing the dimensions of a polygon changes the perimeter, area, and volume, including an explanation of why these changes happen. They should explain it well enough so that a sixth grader could read it and understand. They may illustrate their explanations if they think that will enhance understanding.
