Watch the tower and ground videos in this playlist. The approach is interesting but that is a phase 2 once you join IFATC (you start on ground / tower) After you have been controlling for a while watch them at least once more. Lots of little tidbits in there that are subtle but important.
Study this and pay attention to the details of timing, the order for commands, etc. One note - Tyler issues a “make left / right traffic” the first time a pilot is cleared for the option in a pattern. As long as the pilot is on the same RW and traffic dir as s/he took off from, this is not required. Anytime the RW changes you need to issue a “make XXX traffic” the first clear for the option.
When you feel like you have a good handle on ground, tower and pattern work, open a tracking thread like this one.
Join the ATC Education Group. This will help get people to fly patterns for you that know what they are doing.
