Intro to Blender Mesh Modeling Exercise #1 - Video of Solution?

I'm a newbie Blender user, and just completed Mesh Modeling Exercise #1. I got through it, but am wondering if there is a video that shows an example of how to create the figures. 

I'm sure I did a few things inefficiently since I'm new, so I'm curious to see how an experienced person would have tackled the exercise.
