Sound Walls and the Science of Reading: A Complete Guide for Teachers

Sound walls are powerful tools grounded in the science of reading, helping students connect speech sounds (phonemes) to graphemes through explicit instruction. Unlike traditional word walls—which sort words alphabetically—sound walls organize words by phonemes, articulation, and mouth position, making them far more effective for early decoding.

As you teach my favorite decoding curriculum, UFLI, create your sound wall!

If you also use word walls, visit my Word Walls page for a detailed comparison.

1. What Is a Sound Wall?

A sound wall is a visual display or bulletin board organized around phonology. Sound walls help students understand how sounds are made—the movement of lips, tongue, jaw, and vocal cords. They show:

All 44 phonemes in English
Articulatory mouth photos for each sound
Graphemes that represent each phoneme

Sound walls are typically divided into two parts:

Vowel Valley (vowel phonemes)
Consonant Cave (consonant phonemes grouped by articulation)

2. Why Sound Walls Are So Effective (Science of Reading-Aligned)

Sound walls help students:

Understand how sounds are produced (lips, teeth, tongue)
Strengthen phonemic awareness
Connect speech to print. (See orthographic mapping.)
Improve decoding and encoding
Reduce confusion created by traditional word walls

Support multilingual learners through visual articulation cues
Help students self-correct because they understand how the sound feels

Sound walls are strongly aligned with structured literacy approaches, such as:

UFLI Foundations
Orton-Gillingham
Wilson Fundations
LETRS
SIPPS

Articulation Cards

Articulation cards are helpful when teaching blending because they connect how a sound is made (articulation) with how sounds combine to form words (phonemic awareness and phonics). Approx. $26.

Using articulatory photos encourages students to notice:

Lip movement
Tongue position
Voicing (vibrating vs. non-vibrating vocal cords)

Mirrors

Provide mirrors—kids love watching their mouths form sounds. Here are 15 shatterproof, unbreakable 6 x 4 mirrors. Approx. $17 on Amazon.

3. How to Build a Sound Wall in Your Classroom

Introduce One Phoneme at a Time

As you teach each phoneme and its graphemes, add it to the wall. Sound walls pair wonderfully with UFLI!

Include Articulatory Photos

Use real mouth photos showing the exact articulation.
These help students visually match the formation of the sound.

Add Graphemes

Graphemes (a_e, ai, ay, eigh…)
Practice spelling words with the targeted grapheme. Use orthographic mapping to cement the patterns.

Important! Hang graphemes—not words—because a sound wall is a phoneme–grapheme tool. Words add unnecessary complexity, distract students from the target spelling pattern, and blur the purpose of a sound wall with that of a word wall. Graphemes keep the focus on the sound–spelling connection, support orthographic mapping, and help students build accurate decoding and spelling pathways.
Label Each Section

Use header cards such as
- Stops
- Fricatives
- Glides
- Vowels
- R-controlled vowels
- Diphthongs

4. How to Use a Sound Wall During Instruction (Daily Routines)

Daily Warm-Up Routine

Say the sound
Look at the articulatory photo
Watch yourself in a mirror
Identify voiced/unvoiced
Name the graphemes
Auditory drills—”Write all the ways we’ve learned to write the long a sound.”

During Phonics Instruction

Point to the phoneme on the sound wall
Say it
Air-write the grapheme
Use it in a decodable sentence
Add it to the wall

During Small-Group Reading

When a student becomes stuck, walk to the sound wall:
“Show me the sound at the beginning of this word.”

During Spelling & Dictation

Students reference the sound wall to select the correct grapheme
Explicitly teach: “This is the /ā/ sound. Which spelling do we use in this word?”

Weekly Review

Cover graphemes → students reveal them
Sort words by phoneme
Practice producing the sound correctly

5. Where to Place a Sound Wall

Place your sound wall:

On a wall that students can stand close to
In a quiet, focused area
Near your small-group table
With Vowel Valley on the left and Consonant Cave on the right
At the student’s eye level for younger grades
Avoid placing it behind desks or high up where articulation photos can’t be seen

6. Student Sound Walls (Portable Versions)

Individual student sound walls help:

During writing
During dictation
During small-group lessons
For multilingual learners who need visual cues
For independent practice with new graphemes

You can store them in:

Writing folders
Phonics binders
Chair pockets
Plastic sleeves

Portable sound walls are essential for the transfer to writing. See My Nerdy Teacher for a fantastic portable sound wall.

8. Prepared Sound Walls

This DFZUS sound wall set is a time- and money-saver! No preparation and no paying for color copies.

Sound Wall on Amazon

This sound wall is ready to hang, so you don’t need to spend any more money on color copies! This kit even comes with the mouth articulation cards. Approx. $20 on Amazon.

Sound Wall by My Nerdy Teacher:

If you have access to a color printer, My Nerdy Teacher Sound Wall is a terrific sound wall with different skin tones. Check out their Vowel Valley and Consonant Cave above. It also comes with individual student sound walls.

I purchased this My Nerdy Teacher Sound Wall and had Best Value Copy print them out for me on 8.5×11 “100# Coated Silk Cover paper.” Shipping is a little expensive, but the quality is excellent and the turnaround time is quick. The paper is so sturdy, you won’t need to laminate it. I specified the page numbers I wanted printed to Best Value Copy. You choose between the real images and the clip art versions. Always use real mouth articulation cards, not clip-art ones.

10. Teaching Vowel Sounds: A Powerful Demonstration

Hill for Literacy states, “Vowels carry the voice and tune of a word.”

Try Moats’s (2000) technique:

Use the same two consonants and change only the vowel:

beet
bit
bait
bet
bat
bite
bottle
but
bought
boat
book
boot
Bart
Bert

This helps students hear and see vowel shifts.

11. Consonant Articulation: Place and Manner

Stops (airflow stops, then releases)

p, b (lips)
t, d (teeth/ridge)
k, g (back of throat)

Fricatives (air pushed through a narrow space)

f, v (teeth/lips)
th (two sounds)
s, z (teeth/ridge)
sh, zh (roof of mouth)

Affricates (stop + fricative)

ch (roof of mouth)
j (roof of mouth)

Nasals (air released through the nose)

m (lips)
n (tongue/teeth)
ng (back of throat)

Liquids

r (roof of mouth)
l (ridge/teeth)

Glides (similar to vowels)

y (roof of mouth)
w (back of throat)
h (glottis)

Voicing:

Voiced = vocal cords vibrate
Unvoiced = no vibration

12. Why Sound Walls Are More Effective Than Word Walls

A traditional word wall organizes words alphabetically—not by sound.
This creates confusion:

the appears under t, but starts with /th/
she appears under s, but starts with /sh/

This misrepresents the phonemes students need for decoding.

Sound walls provide the correct phonemic information, which is why many teachers now prefer sound walls over word walls.

13. FAQs

Q: What grades should use sound walls?
A: Sound walls are ideal for K–3 and any older students needing explicit phonics instruction.

Q: Do sound walls replace word walls?
A: Yes—most Science of Reading classrooms replace word walls entirely.

Q: Do I introduce all sounds at once?
A: No. Introduce each phoneme as you teach it in phonics lessons.

Q: What about blends—do they go on the sound wall?
A: No. Blends are not phonemes and should not appear on a sound wall.

Q: Do sound walls support multilingual learners?
A: Yes! Articulation photos give students visual cues for producing unfamiliar sounds.

Q: My sound wall kit comes with words. Should I hang the words?
A: No! Hang graphemes—not words—because a sound wall is a phoneme–grapheme tool. Words add unnecessary complexity, distract students from the target spelling pattern, and blur the purpose of a sound wall with that of a word wall. Graphemes keep the focus on the sound–spelling connection, support orthographic mapping, and help students build accurate decoding and spelling pathways.

14. Common Mistakes Teachers Make

Introducing too many phonemes at once
Using clipart mouths instead of real mouth photos
Placing graphemes before students master the phoneme
Treating the sound wall like decoration
Putting blends (bl, st, dr) on the wall
Not modeling articulation daily
Leaving the wall covered all year
Displaying words on the sound wall.
