You could start off with the nucleus of the sentence, the verb, and all its forms. Then add in the subject to form SV, or intransitive patterns. Then move onto the verb's object to form SVO, or transitive structures, and then copular structures (SV-Subject Complement); then add in prepositional phrases as prepositions have objects too, and that will lead you into ditransitive structures SV-DO-IO. Then introduce SVOC (C = complement) structures, and then SVO-Adjective Structures.
