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 mathematics, 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

  • Gives the sound, not the name, for a taught letter.
  • Blends three letter sounds into a real word.
  • Reads a CVC word without being told the first sound.

What you need

  • Large letter cards for the sounds taught so far
  • Small letter cards, 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. Hold up letter cards. The class says the SOUND.
  2. If anyone says the name, do not correct it out loud — just repeat the sound and move on.
  3. Go faster. Twelve cards in thirty seconds.
“Not what it is called. What it says.”

Teach — pushing the sounds together

11 min
  1. Put out c, a, t in a pocket chart, spaced apart.
  2. Touch each and say its sound. Leave gaps: /c/ ... /a/ ... /t/.
  3. Push the cards together as you say it again, closing the gaps until it is one word.
  4. Do 'sat', 'mat', 'map' the same way. Change only one letter each time so the class can hear which sound moved.
  5. Now do it backwards: say 'pin' and ask which letter goes first.
“Sound, sound, sound — and then push them together and listen for a word you know.”

Guided practice — build it, read it

10 min
  1. Pairs get a set of letter cards. Call a word; they build it and read it back.
  2. Then change one sound: 'you have MAT — make it MAP.'
  3. Watch for pairs who build the word but cannot read it back. Building is a spelling skill; reading it back is the one this standard is about.

Independent practice

7 min
  1. Students complete the first-and-last-sounds page.
  2. Ask readers to sound out aloud rather than in their heads. You cannot diagnose silent blending.

Close

2 min
  1. Put up three letters. Everyone reads the word together on a count of three.
  2. Change one letter and do it again.

What goes wrong, and why

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

Gives the letter's name instead of its sound — 'em' for m.

Why: The alphabet song teaches names, and it is usually the first thing a child learns about letters. Names are useless for blending: 'see-ay-tee' is not 'cat'.

Fix: Never ask 'what letter is this?' during phonics. Ask 'what does it say?' every time, and answer your own question if they hesitate rather than letting the name be said.

Adds a vowel to every consonant — reads 'cat' as 'cuh-a-tuh'.

Why: Most consonants cannot be said alone without a small vowel attached, and the child is reproducing what they were taught faithfully.

Fix: Clip the consonants as short as you can when you model them, and stretch the vowel instead: 'c-aaaa-t'. The vowel is what carries the blend.

Sounds all three letters correctly and then cannot say the word.

Why: The first sound has faded from working memory by the time the third is said. This is a memory problem, not a phonics one.

Fix: Say the sounds faster and closer together, and push the cards physically together as you do it. Speed is the fix, not more practice at the same speed.

If they are not there yet

  • Work with two sounds first: 'at', 'up', 'in'. Then add a letter to the front.
  • Keep the vowel constant for a whole session — only cat, mat, sat, hat — so only one sound is ever new.

If they finish early

  • Four-sound words with an initial blend: 'stop', 'flat', 'grab'.
  • Give a word and ask which letter to change to make another: 'cat to cap'.
  • Ask for a word that is not real — 'zat' — which proves they are decoding rather than recognising.

Exit ticket

Read this word: p i g. Now change the middle letter to e and read it again.

What to look for: 'Pig' then 'peg'. A child who reads the first and cannot do the second is recognising a known word rather than decoding.

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 the sounds taught so far, small letter cards, 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: gives the letter's name instead of its sound — 'em' for m; adds a vowel to every consonant — reads 'cat' as 'cuh-a-tuh' and sounds all three letters correctly and then cannot say the word. 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 this word: p i g. Now change the middle letter to e and read it again.” 'Pig' then 'peg'. A child who reads the first and cannot do the second is recognising a known word rather than decoding. 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 7 September 2026. Please do not resell it or republish it as your own.
