Actually, a VERY easy way to show people sexing EE's by demonstrating with your pictured birds there is by color. EE's are very easily sexed by color, as most are actually sex-linked too.
Females in most cases come out a partridge looking brown and black, often known as wild-type duckwing. Some though are silver too, which is strictly black and white, sometimes with a salmon breast.
Males on the other hand are quite often black and white, but have colored red, orange, or yellow feathers that emerge on sometimes the neck, back, and most importantly and almost always the shoulders. These are tell-tail signs of a male, as females cannot have that color in those regions. Other male colors that are red flags are one coming out with a black breast and red markings on the shoulders, neck, and back. 
True saddle and hackle feathers actually come in much later, so judging by them is a hard thing to do, especially when someone is new with chickens.
I am a total rookie. I am getting some EEs in May, and so am very interested in this post. Thanks for trying to help the newbies! I have a question. In the photos from OP the pullet, Munk, has what I would call orange feathers on her neck, shoulders and back. Illia describes orange feathers on the neck, back and shoulders as tell-tale signs of a cockerel. I am misunderstanding something. Can you please help me understand what I am missing here?
Thank you!
