Write a line of poetry with ten syllables. Modify words and word order to produce an unstressed-stressed rhythm pattern, so that every other syllable, beginning with the second syllable, reads with stress.
Convert an old poem that you have written before, or a poem by a published author, to iambic pentameter. Change the lines to contain ten syllables each that follow the iambic pattern.
Compose a poem in iambic pentameter right from the start. On a piece of paper, copy the iambic pentameter pattern. Leave spaces in between the stressed and unstressed symbols. Underneath write the first line of your poem, composing stressed words underneath stressed symbols and unstressed words under unstressed symbols, until you have written ten syllables. This forces you to structure your lines according to the rhythmic pattern as you write. Repeat this step for every line.
