Phonics instruction teaches children the relationship between the letters of written language and the individual sounds of spoken language. It teaches children to use these relationships to read and write words.
Systematic and explicit phonics instruction is more effective than non-systematic or no phonics instruction. Systematic phonics instruction is the direct teaching of a set of letter-sound relationships in a defined sequence.
The K-3 Phonics sequence was developed and revised by teachers in the Ottumwa Community School District.
