Oddly, this sounds to me like you are more interested in teaching language and rhetoric not reading, if that makes sense. Not that it matters but makes me think differently about recommendations - like making your own language - or talking about roots and things. DS and i just had a fun discussion of di meaning two as we discussed carbon dioxide and nitrogen oxide (which of course produced fascinating looks as we waited for an elevator).
Also there are some great picture books that take a higher level look at things like punctuation and grammar rules, DS loved them around 3-4. Loreen Leedy has some nice ones.
If this isn't what you are thinking, just ignore!!
