Step forward with the LF bringing the RF up (remember, the polka step is similar to a progressive reel movement). Make sure to review with your teacher.

I don't understand the last response. A reel mvmt or polka movement starts with a hop not a step. You finish your intro with an extension and slap to 4th int with the LF. You hop bringing the LF in to 3rd aer to start the step. This movement always starts with a hop and to start with any other foot would require the dancer to spring. So in short...start the first halfwith LF and the 2nd half with the RF.

thanks a bunch!

In the book, it does say "similar to a prog. reel". What, exactly, is the difference? No one around here does it for me to look...

whats a polka step?

In the Sailor's Hornpipe, there are different methods (alternatives) to perform the first step. The polka step is just one of them.
