How to Teach Letter Sounds

Quick answer

To teach letter sounds, start with the letter’s name, show your child how your mouth moves when you make the sound, and practice with real words that start with that letter. Say the sound short and crisp (like /m/, not “muh”), and keep sessions to 5 or 10 minutes. Most kindergarteners learn the 26 basic letter sounds over the school year with daily practice.

Letter sounds are the building block for reading. Once your child knows what sound each letter makes, they can start blending those sounds into words. Below is a step-by-step guide to teaching letter sounds at home, the mistakes to watch for, and activities that make letter sounds practice feel like play.

What are letter sounds and why do they matter?

A letter sound (also called a phoneme) is the noise a letter makes in a word. The letter M makes the /m/ sound you hear at the start of “mom,” and the letter S makes the /s/ sound in “sun.” Learning these sounds is the foundation of phonics, which is how kids learn to decode (sound out) words.

In kindergarten, children work on recognizing and producing the sounds for all 26 letters, which aligns with Common Core Reading Foundational Skills standard RF.K.3.A: “Demonstrate basic knowledge of one-to-one letter-sound correspondences by producing the primary sound for each consonant.”

Step-by-step: how to teach a letter sound

Here’s the routine that works for one letter at a time. Repeat it daily with the same letter for a few days, then move to the next.

Show the letter and say its name. Hold up a card or point to the letter in a book. “This is the letter S.”
Say the sound, short and clear. “S says /s/.” Make the sound quick, not “suh” but just /s/, like a hissing snake. Your child should hear the pure sound without an extra vowel tacked on.
Show how your mouth moves. Exaggerate a little so they can see your lips, teeth, and tongue. For /s/, your teeth are close together and air hisses out. For /m/, your lips press together.
Give a word that starts with that sound. “S says /s/ like in ‘sun.’ Can you say /s/, /s/, sun?”
Let your child try. Have them repeat the sound and the word. If they get it wrong, model it again and let them try a second time.
Practice with more words. “What other words start with /s/? Snake, sock, silly!” Let your child come up with ideas, even if they’re silly.

What order should you teach letter sounds?

Start with the letters in your child’s name. Kids are motivated to learn their own name, and it gives them a personal connection to the letters.

After that, move to the most common consonants and short vowels:

Consonants: m, s, t, p, b, f, n, r, l, d, g, h, k, c (hard c like “cat”), j, v, w, y, z, q, x
Short vowels: a (like “cat”), e (like “bed”), i (like “sit”), o (like “hot”), u (like “cup”)

Avoid teaching look-alike or sound-alike letters back-to-back (b and d, m and n, p and q) so your child doesn’t confuse them. Spread those out.

Fun ways to practice letter sounds at home

Letter sounds practice works best when it’s woven into daily life and feels like a game. A few ideas:

Letter of the week: pick one letter and hunt for it everywhere (on signs, food labels, in books). Say its sound every time you spot it.
Sound sorting: gather small toys or objects and sort them by starting sound. All the /b/ things in one pile, all the /s/ things in another.
I spy: “I spy something that starts with /t/.” Your child guesses and says the sound.
Alphabet books: read books where each page features a letter and its sound, like Chicka Chicka Boom Boom or Dr. Seuss’s ABC.
Playdough letters: form a letter out of playdough and say its sound while you shape it.
Apps with read-aloud: apps like Octolearn let kids practice letter sounds on their own with audio support, so they hear the sound pronounced correctly every time.

Keep sessions short. Five or ten minutes a day beats a long, frustrating session once a week.

How to know your child has learned a letter sound

Your child has mastered a letter sound when they can:

Name the letter and say its sound without prompting.
Point to the letter when you say its sound (“Show me the letter that says /m/”).
Think of a word that starts with that sound.
Recognize the sound at the beginning of words you say out loud.

Once they can do that for most of the alphabet, they’re ready to start blending sounds into simple words (like blending /c/, /a/, /t/ into “cat”), which is the next big reading skill.

The easiest way to give your child daily practice

The hardest part of teaching letter sounds isn’t the teaching itself. It’s keeping your child engaged day after day and making sure they hear each sound pronounced correctly. That’s where Octolearn helps: you describe what your child is working on (“letter sounds for kindergarten”), and it generates a practice set with read-aloud on every question, a hint and a second try before the answer, and stars and animal buddies that keep kids motivated. It’s free to try, and it takes the pressure off you to come up with new activities every single day.

Frequently asked questions

What order should I teach letter sounds?

Start with the letters in your child's name, then move to common consonants (m, s, t, p, b) and short vowels (a, e, i, o, u). This matches how most kindergarten programs teach phonics. Avoid teaching letters that look or sound similar back-to-back, like b and d or m and n, so your child doesn't mix them up.

How long does it take to learn all the letter sounds?

Most kindergarteners learn the basic 26 letter sounds over the course of the school year, usually by late spring. The pace varies: some kids pick up sounds in a few weeks, others need several months. Short, daily practice (5 to 10 minutes) works better than long sessions once a week.

Should I teach letter names or letter sounds first?

Teach the letter name first, then immediately pair it with its sound. Knowing the name gives your child a hook to remember the letter, and the sound is what they need for reading. For example, say "This is the letter M, and it says /m/ like in 'mom.'" The two go together from the start.

What is the difference between a letter name and a letter sound?

The letter name is what we call it (like "bee" for B), and the letter sound is the noise it makes in words (like /b/ in "bat"). Letter names help kids recognize and talk about letters, but letter sounds are what they use to sound out words when reading.

How do I practice letter sounds at home without it feeling like school?

Use real life: point out letters on signs, cereal boxes, or in books you're already reading together. Play quick games like "I spy something that starts with /s/" or have your child find all the things in the room that begin with a certain sound. Apps like Octolearn turn letter sounds practice into a game with read-aloud support and animal buddies to unlock.
