In class we have been learning about writing Haikus. "Haiku" is a traditional form of Japanese poetry. Haiku poems consist of 3 lines. The first and last lines of a Haiku have 5 syllables and the middle line has 7 syllables. The lines rarely rhyme.
Here's a Haiku to help you remember:
I am first with five
Then seven in the middle --
Five again to end.
