In this class, students will learn the basics of poetry (rhyme scheme, rhythm, stanza, etc.) and then learn to write their own limerick. The class will be a combination of group learning for concepts, practice and introductions. Then, students will work both individually and in small breakout groups on their own poems. 
I teach by teaching basic concepts, introducing students to examples, and then having them apply their knowledge to confirm understanding. I would use lecture, reading, discussion and practice to teach the concepts. Day 1 would introduce students to the necessary poetry concepts. Day 2 would continue student understanding of basic poetry concepts and begin the process of writing . Day 3 students would edit other students poems for structure and fun. 
Students don't need any prior knowledge of poetry and limericks to participate. However, if they are already very familiar with poetry, this class would be too basic for them.
