So, repetition is used in poems to show emphasis on a particular point. For your groupwork project you could possibly write a poem or a song and add repeated words to show you understand how to use repetition and when to use it.
Dear Naya, I want you to enroll at my school! It's the best of all schools. It provides longer breaks, fun teachers, amazing after-school activities, longer recess, and an science lab! Every Monday, we get rice crispy treats for free! On Tuesday, after lunch, we'll go to the gym and play some awesome activities! On Wednesday, after 4th period, we'll go to the music room and hear a solo and rate it! Lastly, on Thursday, instead of going to school, we get a break! So, that's 3 days of school, and 4 weekends! If you enroll to my school, it'll be fun as a bouncy house!
<em>Sincerely, Lily.</em>
