It's very easy to draw a electron dot diagram and a Lewis Diagram. They are both about the same. Just for the Lewis Diagram, the electrons that are bonded between elements are a straight line, instead of a paired electron dot.
The nucleus is represented by the atomic symbol. For individual elements determine the number of Valence electrons. Electrons are represented by dos around the symbol. Four orbitals (one of each side of the nucleus) each holding a maximum of 2 e- (recall: maximum of 2 electrons perorbital). Each orbial gets 1 e- before they pair up.
The dots are placed in 4 groups of one or two electrons, with 8 electrons representing a closed shell or noble gas configuration. The dots are placed on the 4 sides in pairs as a reminder that electrons are paired in the orbitals.

Here are some practise problems from the internet:
