Which practice is NOT characteristic of systematic phonics instruction?

Systematic phonics instruction focuses on a structured curriculum where sound-letter relationships are taught in a sequential and organized manner. This method emphasizes consistent review of sound-letter relationships, ensuring that students build a solid foundation in phonics. Utilizing phonics games aids in reinforcing these concepts through engaging and interactive practice, further supporting the systematic approach.

The choice of addressing phonic patterns as they arise during reading is characteristic of a more incidental or implicit approach to phonics instruction, rather than a systematic one. In systematic phonics instruction, explicit teaching of sound-letter relationships occurs first, and then students apply these skills during reading sessions. Therefore, addressing patterns as they come up is not fitting with the structured nature of systematic phonics instruction, making it the correct selection for the question.

Using flashcards for sight-word practice, while not strictly phonics instruction, can complement it by reinforcing recognition and fluency with high-frequency words, but it does not inherently focus on the systematic teaching of sound-letter relationships.
