In a planned sequence of phonics lessons, a kindergarten teacher introduces the consonants p, t, b, m, and s before introducing any vowels. Which statement identifies an evidence-based rationale for sequencing the lessons this way?

• A. Vowels Have More Than One Sound And Are More Challenging Than Consonants To Learn
• B. Letter-Sound Correspondence Of Consonants Is Easier For Students To Learn Than That Of Vowels
• C. Students Are More Familiar With These Consonants So They Will Generally Learn Them Faster Than Vowels
• D. Consonants Such As These Can Be Used To Create Easily Decodable Words Once A Vowel Is Introduced

Answer: (D)

Introducing a small set of consonants before introducing vowels supports early decoding by enabling blending to form decodable words once vowels are added. When children learn consonant sounds first, they gain a solid foundation for treating words as blends of separate sounds. Once vowels are introduced, those same consonants can be combined with the new vowel sounds to create simple, decodable words (for example pat, sit, mat, sat, bit, lip). This immediate ability to read and sound out real words reinforces the link between letters and sounds and builds confidence in applying phonics rules to reading. The other options describe aspects of vowels or familiarity, but they don’t capture the practical instructional rationale for sequencing consonants first to support quick, decodable word reading after vowels arrive.
