Regarding phrasal verbs, I like to suggest mnemonics.
If you have every preposition or phrasal verb ending in English paired with a mnemonic image (IN = Tunnel, UP = elevator, DOWN = Cannonball, WITH = Chains
To put down – Use an example sentence and then involve a cannonball in your imagery for that sentence (ONLY DO THIS WHEN YOU GET A FLASHCARD FOR THIS SENTENCE WRONG!)
To put up with – Use an example sentence and then involve an elevator and/or chains in the story, but only add those images if you have trouble with one or both parts of the phrasal verb. (i.e., If you forget the ‘with’, then put chains in the story.)
