What Is the Alphabetic Principle? Building the Foundation of Learning to Read and Write

From a very young age, before children can walk or talk, they are exposed to letters in the alphabet. Before they even reach preschool in the United States, many children have participated in library programs like 1000 Books Before Kindergarten or had family members read books to them. They have likely heard and sung the alphabet song and viewed letters in their environment. There are many opportunities to interact with letters—both physically and/or digitally in books, signs, and on objects. Can we say these children understand the alphabetic principle?

Alphabetic Principle Definition

One of the most crucial concepts a child must understand if they are to learn to read is the alphabetic principle. In the English language, the alphabetic principle is the understanding that phonemes (sounds) in spoken language are represented by letters and combinations of letters in written language. It is the recognition that letters and sounds are connected and that words are made up of individual sounds that are represented by specific letters or combinations of letters.

The alphabetic principle is the foundation of phonics instruction, which teaches children how to decode and read words by associating sounds with specific letters or letter combinations. The alphabetic principle is a crucial component of reading development and is essential for building strong literacy skills.

Why Is the Alphabetic Principle Important?

The alphabetic principle may seem like a simple concept for children to grasp, but given that the English alphabet’s letters and sounds can be so arbitrary, students require explicit, systematic instruction in phonological awareness, phonemic awareness, letter names, letter sounds, and decoding and encoding (i.e., spelling and writing). Although students may not learn the term “alphabetic principle,” they cannot learn to read without it. “Insight into the alphabetic principle (letters represent sounds in a predictable system, and words comprise patterns of letters and corresponding sounds) is especially critical for learning to read.” It is essential that high-quality literacy programs include instruction and practice that support students’ understanding.

What Is Phonemic Awareness?

Phonemic awareness is the ability to notice, think about, and manipulate the individual sounds in spoken words. It is a crucial pre-reading skill that is closely related to the alphabetic principle. Although phonemic awareness and the alphabetic principle both focus on the sounds of spoken language and their representation in written words, phonemic awareness is focused on the sounds of spoken words, while the alphabetic principle is focused on the relationship between those sounds and the letters that represent them in written words. Both are important for learning to read and are often taught together as part of a comprehensive reading program, such as HMH Into Reading.

How Do Phonological Awareness and Phonemic Awareness Help Establish the Alphabetic Principle?

While “an awareness of phonemes is key to understanding the logic of the alphabetic principle and thus to the learnability of phonics and spelling,” neither phonological awareness nor phonemic awareness on their own are sufficient for the development of the alphabetic principle. In combination, however, they do lead to transfer in pre-literate children. For example, “before children demonstrated mastery of the alphabetic principle, they needed to know that /m/ is a component of /mat/, that words like /mat/ and /mow/ start with the same component, and that /m/ is symbolized by a particular graphic form.”

How Can Teachers Support Students’ Understanding of the Alphabetic Principle?

Overall, teachers should approach teaching the alphabetic principle with intentionality, explicit instruction, consistency, and creativity to support students’ understanding of this important foundational skill.

1. Explicitly teach letter-sound correspondences: Teachers should explicitly teach students the connections, or associations, between letters and the sounds they make in order for students to understand how words are formed and how to manipulate them to create new words. This can be done through phonics instruction, and instruction and practice can include using multisensory approaches like singing, chanting, and manipulating letter tiles.
2. Use phonemic awareness activities: Phonemic awareness is the ability to hear, identify, and manipulate individual sounds, or phonemes, in spoken words. Teachers can use various phonemic awareness activities such as blending, segmenting, and substituting sounds to help students understand how sounds create words.
3. Model letter-sound relationships: Teachers should model decoding strategies and demonstrate how to sound out unfamiliar words by using letter-sound correspondences.
4. Use decodable texts: Teachers should provide students with decodable books that contain words that follow predictable sound-spelling patterns. Using these texts helps students apply their knowledge of letter-sound correspondences in context.
5. Engage in phoneme segmentation activities: Teachers can help students break words down into their component sounds by engaging in phoneme segmentation activities. These activities help build students’ phonemic awareness and support their understanding of the alphabetic principle.
6. Provide opportunities for practice: Students need ample opportunities to practice their alphabetic skills to internalize and retain them. Teachers should provide students with opportunities to practice decoding and encoding words daily. Teachers can engage students in activities like word sorts, word hunts, reading games, and interactive whiteboards that provide an engaging way to practice and reinforce their learning.
7. Scaffold instruction according to student needs: Teachers should assess students’ current knowledge of letter-sound correspondence and then differentiate instruction to meet the needs of all students. This may involve providing additional support for striving readers or offering more challenging texts for advanced readers. Providing varying levels of support for students allows them to progress at their own pace and ensures that they have the necessary support to succeed.
8. Connect learning to real-world applications: Teachers can make learning more meaningful by connecting it to students’ lives and showing how the alphabetic principle is used in the real world. For example, reading labels on products, identifying street names, and decoding signs can all be alphabetic principle examples that show the practical application of letter-sound correspondence.

Instructional Activities to Support the Acquisition of Alphabetic Principle Knowledge

Decades of research, including work by Marylin J. Adams, the National Reading Panel, the National Early Literacy Panel, and the National Research Council, have demonstrated that understanding the alphabetic principle is essential to learning to decode, encode, and read and write fluently. Below are some examples of instructional activities that can support your students’ understanding of the alphabetic principle.

Activity 1: Letter Recognition Games

Play games like “I Spy” or “Alphabet Bingo” to help kids recognize and identify letters.

For “I Spy,” have a student pick an object everyone can see. Then, that student can give the first letter of the word as a clue. For example, if the student sees a chair, they can say, “I spy something that begins with the letter C.” Other students then take turns trying to guess what object they are thinking of.

For “Alphabet Bingo,” search online for a bingo card generator to create templates for the classroom. Hand the different versions of the cards out to students in class. Shuffle a stack of alphabet cards, draw one card at a time, and say the letter out loud. Have the students cover the letter on their board if they see it. Whoever fills a row first on their board is the winner!

Activity 2: Alphabet Books

Have students read books with letters and the alphabet, such as Dr. Seuss’s ABC and Chicka Chicka Boom Boom. Here’s a list of a few books to consider:

• LMNO Peas by Keith Baker
• Eating the Alphabet by Lois Ehlert
• Chicka Chicka Boom Boom by Bill Martin Jr. and John Archambault, illustrated by Lois Ehlert
• Dr. Seuss’s ABC by Dr. Seuss
• Creature ABC by Andrew Zuckerman

Activity 3: Letter Manipulatives

Use letter blocks, magnets, or foam letters for children to manipulate and use for spelling and word building. Provide large paper or a magnetic board in the classroom and give students time to play around with the letters.

Activity 4: Clapping or Counting Syllables

Help children understand the concept of syllables by clapping or counting them in words. For example, clap each student’s name and count the syllables as you sound them out.

Activity 5: Word Families

Teach children about word families, such as “cat,” “bat,” and “hat,” which share the same ending sound and spelling. You can write a series of words on index cards and then have students group them by their sounds.

Activity 6: Rhyming Games

Play rhyming games and encourage children to generate their own rhyming words. For example, have students sit in a circle. One student can start by saying a word. The next student can say the original word and then a rhyming word. Continue around the circle. These games can be done in small groups or with the whole class.

Activity 7: Letter Sound Activities

Practice identifying and producing the sounds of each letter, either through visual aids or phonetic songs and chants. Some examples of songs that students can sing include “Mary Had a Little Lamb” and “Apples and Bananas.”

Activity 8: Connect learning to real-world applications

Teachers can make learning more meaningful by connecting it to students’ lives and showing how the alphabetic principle is used in the real world. For example, reading labels on products, identifying street names, and decoding signs can all be support students’ understanding of the alphabetic principle through examples that show the practical application of letter-sound correspondence.

Activity 9: Alphabetical Order

Teach children how to arrange letters in alphabetical order, making connections between the sequence of the letters and the order of the sounds. You can write letters on individual index cards and scramble them. Have students take a stack and arrange them in alphabetical order.

Activity 10: Spelling Games

Play games that involve spelling, encouraging children to break down words into individual sounds and matching them to the correct letters. You can use index cards with letters on them. Have students choose ten at random and then try to spell a word with their cards.

The alphabetic principle is a foundation for learning to read and write in any language that uses an alphabetic writing system. Therefore, understanding the alphabetic principle is crucial for early literacy development, as it allows children to decode printed words and understand the relationship between letters and sounds. Helping students to understand the alphabetic principle will hopefully instill a love of reading and will set them up to become lifelong readers.
