1. Play against your computer but notate anyway. Set it at a level where you lose sometimes. Young kids/beginners should set it at a level where they lose 1 out of 4 games. Advanced players should set it at a level where they lose 3 out of 4 games. Notate even though you the computer notates for you. The key is to get used to the "rhythm" of notating. Get used to the process. If you can patiently notate against the computer that instamoves (moves instantly) then you can be patient against any opponent. Learn to enjoy the process of notating. Remember, notating a chess move will be easier than writing your own name and some day you will hate playing unnotated chess (unless you are under 5 minutes).
2. Read chess books that are readable. Most chess books discourage young readers (and adult readers). Start off with "How to beat your dad in chess." Don't buy your chess books based off amazon.com reviews! There are so many 5 star chess books that will discourage kids from reading.
3. Use ChessMagnet.Com or any similar site.
Don't just play your family member. If you do play your family member, notate. Playing low quality unnnotated games is bad for you! Unnotated games are bad for you! The only time you should not notate is when you have a clock and you have 5 minutes or less.
Don't just search the app store and play a chess app hundreds of times on your phone or tablet. Consider doing something like I described in the first paragraph of this blog post.
