Volumes of Cross-Sectional Solids (part 4 of 4)

Have students take out their Volumes of Cross-Sectional Solids sheet that we gave them 2 days ago, and talk through one or two of these examples to summarize the process for drawing and labeling the picture, writing the area expression for the cross-section, and integrating to obtain the volume.  Although we distributed this sheet on the 2^nd day of this set of 4 lessons, for some students this sheet will make more sense now that we have spent more time with cross-sectional solids.  Students may refer to this sheet throughout class today as they check the mathematics in other groups’ pipe cleaners projects.
