Letters and the Sounds They Make

A 35-minute Kindergarten lesson on matching letters to sounds and blending them into a word, which is the moment reading starts.

Letters and the Sounds They Make is a free 35-minute Kindergarten English lesson plan for Common Core standard RF.K.3 — match letters to their sounds and blend them to read simple words. It is timed across 5 sections, gives the exact wording to use where the wording carries the meaning, names 3 misconceptions with the teaching move that addresses each, and ends with an exit ticket and a printable worksheet with its answer key.

RF.K.3

Know and apply grade-level phonics and word analysis skills in decoding words.

Objective

Students will be able to say the sound each taught letter makes and blend three of them into a word.

Students are successful when they can

  • Says /s/ for s, /a/ for a, /t/ for t, /p/ for p, /i/ for i, /n/ for n, without the letter name.
  • Reads "sat," "pin" and "tap" by saying each sound and blending.
  • Builds "nap" from letter cards when it is said aloud.

What you need

  • Large letter cards for s, a, t, p, i, n (or the sounds taught so far)
  • Small letter cards s, a, t, p, i, n, one set per pair
  • A pocket chart or a table everyone can reach
  • The printable practice sheet linked at the end of this plan

The lesson

Warm-up — sound, not name

5 min
  1. Flash each large card. The class says the SOUND, not the name: s says /s/, not "ess."
  2. Add an action for each: /s/ snake hand, /a/ hand on cheek as if surprised, /t/ tap the table, /p/ puff out a candle, /i/ wiggle fingers like an itch, /n/ nod.
  3. Mix up the order and go faster. Note any child who says the letter name.
“Tell me what it says, not what it is called.”

Teach — pushing the sounds together

11 min
  1. Put s, a, t in the pocket chart with a gap between each. Touch s: /sss/. Touch a: /aaa/. Touch t: /t/.
  2. Slide them closer and say faster: /sss-aaa-t/. Slide them together and sweep under: "sat." Ask: "Is sat a real word?" Fish for "the cat sat down."
  3. Do "pin" the same way. Then let the class do "tap" with you, and "nap" on their own while you only touch.
  4. Say: "Now I change one letter." Swap the t in "sat" for p: "s-a-p, sap." Swap s for t: "tap." Ask what changed each time.
  5. Spelling the other way: say "pat." Ask: "What is the first sound? /p/. Which card?" Build p-a-t with the class telling you each card.
  6. Read "it" and "at" as two-letter words to show that blending works on short words too.
“Say each sound, keep your voice going, and push them together until you hear a word.”

Guided practice — build it, read it

10 min
  1. Each pair has s, a, t, p, i, n cards. Say a word: "sit." Pairs build it, then one child reads it back by touching each card.
  2. Continue: "pan," "tin," "tip," "nap," "pit," "ant."
  3. Then reverse it. You build a word in the pocket chart; pairs blend it aloud: "spin" (four sounds, a stretch), "pat," "sip."
  4. Circulate and watch the "stop and start" blenders who say /s/ - /a/ - /t/ and then "sad" or "tap." Have them keep the voice going without a gap.
“Your turn. Touch, say, push it together.”

Independent practice

7 min
  1. Read the picture names on the sheet aloud.
  2. Children circle the letter that matches the first or last sound of each picture, then sort three-letter words by their middle sound into columns.
  3. Encourage whispering each word out loud while working.

Close

2 min
  1. Show a word card nobody has seen today: "tan." Ask the class to blend it together.
  2. Ask: "Did you know that word before, or did you read it?" Point out that they read it.

What goes wrong, and why

Each of these is a reasoning error rather than carelessness. The fix addresses the reasoning.

Says letter names and cannot blend them: "ess-ay-tee... sat?"

Why: Letter names are what the alphabet song teaches, and the name of most letters is not its sound.

Fix: Ban names during blending, kindly: "Names are for the alphabet song. Sounds are for reading." Keep the action for each sound as a reminder.

Says all three sounds correctly, then guesses a different word: /s/ /a/ /t/... "sad."

Why: The sounds are said separately with gaps, so by the third one the first has faded from memory.

Fix: Stretch continuous sounds into each other with no gap: "sssaaat." Practice blending just the first two before adding the third.

Reads "pin" as "nip," or "tap" as "pat."

Why: The child sees the letters but has not yet fixed that reading goes left to right in the word as well as across the line.

Fix: Touch each card in order from left to right with a finger, and say a sound only when the finger is on it.

If they are not there yet

  • Use only two vowels' worth of words and continuous first sounds: "sat," "sap," "nap," "nip."
  • Blend two-letter words first: "at," "it," "in," "an."
  • Keep the sound actions in every step, said with the sound.

If they finish early

  • Blend four-sound words: "spin," "snap," "past," "ants."
  • Read a nonsense word ("tib," "pon") and say why it is not real, which proves blending rather than memory.
  • Write a caption with taught letters only: "a pin," "tap it."

Exit ticket

Read these three cards: "sat," "pin," "nap." Then build "tip."

What to look for: All three read and "tip" built t-i-p. Right sounds but wrong word means gaps between sounds. Letter names mean the sound habit is not there yet. "Pit" for "tip" means the child built or read right to left.

Questions about Letters and the Sounds They Make

How long does the Letters and the Sounds They Make lesson take?

35 minutes, split across 5 timed sections: warm-up 5 min, teach 11 min, guided practice 10 min, independent practice 7 min, close 2 min. The minutes are stated per section and add up to the stated length, so the plan can be cut or extended at a section boundary rather than abandoned halfway.

Which standard does Letters and the Sounds They Make teach?

CCSS.ELA-LITERACY.RF.K.3 — RF.K.3, Reading: Foundational Skills for Kindergarten: “Know and apply grade-level phonics and word analysis skills in decoding words.” In plain terms, match letters to their sounds and blend them to read simple words.

What do I need to teach this lesson?

Large letter cards for s, a, t, p, i, n (or the sounds taught so far), small letter cards s, a, t, p, i, n, one set per pair, a pocket chart or a table everyone can reach and the printable practice sheet linked at the end of this plan. Everything listed is either ordinary classroom equipment or a free printable from this site — there is nothing to buy and nothing to prepare beyond photocopying.

What mistakes should I expect in this lesson?

Three, each a reasoning error rather than carelessness: says letter names and cannot blend them: "ess-ay-tee... sat?"; says all three sounds correctly, then guesses a different word: /s/ /a/ /t/... "sad." and reads "pin" as "nip," or "tap" as "pat.". The plan gives the thinking behind each one and the teaching move that addresses the thinking rather than the symptom.

How do I know whether the lesson worked?

The exit ticket asks: “Read these three cards: "sat," "pin," "nap." Then build "tip.".” All three read and "tip" built t-i-p. Right sounds but wrong word means gaps between sounds. Letter names mean the sound habit is not there yet. "Pit" for "tip" means the child built or read right to left. That tells you whether the class needs a reteach or a thirty-second conversation before you plan tomorrow.

Is there a worksheet to go with Letters and the Sounds They Make?

Yes — 1 printable RF.K.3 worksheet, linked at the end of the plan and free like the rest of the site. Each one comes with an answer key and 25 versions, so the practice after the lesson can be a different paper on every desk.

Is Letters and the Sounds They Make free to use?

Yes. The plan, its printables and their answer keys are free to read, print and photocopy for your own class, with no account and no email capture. It was last reviewed on October 8, 2026. Please do not resell it or republish it as your own.
