10/14 (could have been 12/14, but I doubted myself)
But I fail to see how knowing some of these will improve literacy. Technical knowledge will definitely be improved, but literacy is about being able to use the skills. You can have a technically gifted musician who does not play musically, or a less technically gifted musician who I would rather listen to because they make beautiful music.
I don't need to know a sentence contains a subordinate clause or is written in the active/ passive voice to write beautifully.
Spelling is very important. Reading lots and lots (that's for the teachers who hate 'got', 'lot' and 'nice'
)will help with writing and composing written work well. This grammar knowledge will aid grammar knowledge... There's a time and a place for that...
