What are some tips that kids could use to learn the lines of a musical school play? Write them as if they are narrated by an elementary school student.

One good method is to practice your lines of the play with other people, who might not necessarily be in the play (for example, practice with your parents!). It's also good to review your lines and repeat them by heart a few minutes later. Then over time try to repeat them without looking at the play book. One thing to avoid is to only read the lines but not say them out loud. Saying the lines out loud is really important for remembering them and practicing your acting. And above all, try to have fun!
