You can teach verbs by getting the pupils to write a couple of sentences without using any. It's enjoyable as it's complete nonsense. eg I my breakfast of Coco Pops and toast later my teeth before skirt over my head etc
I think you could teach abstract nouns by a sort of I Spy/Talking Heads eg finding lots of adjectives to describe it and then guessing/revealing what it is.
You can also use colours, pictures and symbols to replace a certain part of speech. This also works well with punctuation (but not as good as sound punctuation!
