I don't write a lot of poetry, although I like poetic language in prose. I wrote the following poems as part of the market-leading Years 7-10 mathematics textbook series, Pearson Mathematics, that I published in my day job with Pearson and co-wrote. Each poem appears on the inside front cover and was written to describe the mathematics inherent in the cover image. The poems are all Fibs, which means the number of syllables follows a Fibonacci sequence: 1, 1, 2, 3, 5, 8... A Fibonacci sequence is one where each term is the sum of the two previous terms in the sequence. I based my Fibs on the 6-term Fibonacci sequence that starts with 1, 1. Theoretically, you could start a Fibonacci sequence with any two numbers and have more than six numbers in the sequence. In practice, after the sixth line in a Fib, the number of syllables starts to increase rapidly, so there's a pratical limit to the number of lines. I like the aesthetics behind Fibs - which is similar to Haiku - where the structure leads to a stark simplicity.
