All language learning follows the same pattern: we go from simple sentences (doggies jumped), we change their forms to -ing forms (doggies jumped), and then we go to irregular past (birdies went). Then regular past tense verbs (Doggie jumped) and third person present tense (Daddy eats).
To make sentences:
Take the first example out of your grammar book. and make a flashcard.
When you see new words or word forms that surprise you, make flashcards based on them.
