Sounds and Letters

Foundations

Say your name out loud. Say it slowly. Can you hear the pieces? Every word you say is made of small sounds. Your ears can find them. Your mouth can say them one at a time. That is where reading starts.

Letters are a code for those sounds. The letter m stands for /m/. Put letters in a row and they spell a word. Learn the code and the letters tell you what to say. Cat. Ship. Cape. Words you can read all by yourself.

In this unit you will hear the first sound, the last sound and the middle sound. You will rhyme and clap. You will blend sounds into words and take words apart. Then you will learn the letters, the vowels, the letter teams and the silent e. By the end, you will crack the code.

Sounds in Words

Phonological Awareness
Big questionWhat do you hear inside a word?
The story

I Spy With My Ears

The clue is not a color. The clue is a sound.

It is rug time in Ms. Ortiz's class. She says, "Let's play I Spy. But today the clue is a sound." The kids lean in. Ms. Ortiz says, "I spy something that starts with /b/." She says the sound, not the letter. Just /b/, like a bubble popping.

Hands go up. "Ball!" says Devon. Ms. Ortiz shakes her head. "Good try. Ball does start with /b/. But I do not see a ball." Kids look around the room. There is a clock. There is a door. There is a book.

Priya says the word slowly. "Buh... book. Book starts with /b/!" Ms. Ortiz smiles. "Yes! The first sound in book is /b/." Now it is Priya's turn. She looks around. She says, "I spy something that starts with /d/."

Devon says, "Door!" He is right. Every word in the room has a first sound. Clock. Rug. Window. Once you hear the first sound, you can play this game anywhere.

Talk about itLook around your room. Pick one thing. What sound does its name start with?
Section 1

Hearing Sounds

1.1

Words Are Made of Sounds

Main ideaEvery word is made of small sounds put together.

Say the word cat. Now say it very slowly. Stretch it out. Do you hear it? C... a... t. Cat is not one sound. Cat is three sounds. They are stuck together.

Every word is like this. A is a set of said in a row. Say sun slowly. S... u... n. Three sounds. Say go slowly. G... o. Two sounds.

Your ears can pull a word apart. Your mouth can say each piece. This is a big skill. When you hear the sounds, you are ready to read them.

Blending puts sounds together. Now go the other way. Say the word hop. Pull it apart. /h/... /o/... /p/. You broke hop into three sounds. That is .

Use your fingers. Say sit. Hold up one finger for each sound. /s/ is one. /i/ is two. /t/ is three. Three fingers. Three sounds.

This helps you spell. To write a word, you need its sounds. Say the word. Take it apart. Then write one letter for each sound you hear.

Chapter

Letters and the Code

Phonics
Big questionHow do letters turn sounds into words you can read?
The story

Cracking the Code on Ship

Four letters. Three sounds. One class that would not give up.

Mr. Bell writes a word on the board. S-h-i-p. "Who can read this?" he asks. Nobody says a thing. The class knows /s/. They know /h/. But together the letters make a strange word. Suh-hip? That is not a word.

Then Ava says, "Wait. What if s and h are a team?" Mr. Bell nods. He puts his finger to his lips. "Shhh." The class laughs. That is the sound! Two letters, one sound. /sh/.

Now they try again. Ava points to each letter, left to right. /sh/... /i/... /p/. She says it faster. Ship! The whole class says it. Ship! A boat on the lake. They just cracked the code.

Mr. Bell writes more words. Shop. Fish. Dish. Now the class can read them all. Once you know the code, the letters tell you what to say.

Talk about itWhat made ship hard to read at first? What made it easy at the end?
Section 1

What a Letter Is

2.1

A Name and a Sound

Main ideaEvery letter has a name and a sound, and the sound is what you read.

Look at the letter m. Its is em. But when you read, you do not say em. You say its : /m/. Say it. Your lips press together. Mmm. That is the sound of m.

Every letter has both. The letter s is called ess. Its sound is /s/, like a snake. The letter t is called tee. Its sound is /t/, a quick tap.

The name helps you talk about the letter. The sound helps you read the word. Map is not em-ay-pee. Map is /m/ /a/ /p/. Sounds make words.

Words to know
name
what a letter is called, like em for the letter m
sound
what a letter says in a word, like /m/ for the letter m
Check yourself

1. What is the sound of the letter m?

2. Which one helps you read a word?

3. What is the letter s called?

2.2

Big Letters, Small Letters

Main ideaEach letter comes in a capital and a small form, and both say the same sound.

Look at B and b. They look different. One is big. One is small. But they are the same letter. Both are bee. Both say /b/. The big one is a letter. The small one is a letter.

Capitals do a special job. A name starts with a capital. Maria. Chicago. The first word in a sentence starts with a capital too. The dog ran.

Most letters in a book are small. Capitals show up at the start of things. Look at your name. The first letter is a capital. The rest are small.

Words to know
capital
the big form of a letter, like B
lowercase
the small form of a letter, like b
Check yourself

1. What is the big form of a letter called?

2. Do B and b say the same sound?

3. Where do you see a capital letter?

2.3

Vowels and Consonants

Main ideaFive letters are vowels, and every word needs at least one.

Say /a/. Your mouth is open. Air comes out with nothing in the way. Now say /t/. Your tongue taps. Something blocks the air. Open sounds are . Blocked sounds are .

The vowel letters are a, e, i, o and u. Just five. All the other letters are consonants. B, c, d, f, g and more.

Every word needs a vowel. Look at cat. The vowel is a. Look at dog. The vowel is o. Try to say a word with no vowel. Bkt? It is not a word. The vowel holds the word together.

Words to know
vowel
one of the letters a, e, i, o, u; its sound comes out with an open mouth
consonant
any letter that is not a vowel, like b, s or t

Section 2

Reading Short Words

2.4

Short Vowels

Main ideaIn a short word like cat, the vowel says its short sound.

Look at the word cat. The vowel is a. Here it says /a/, like the start of apple. This is the of a. Say cat, hat, bat, map. Every one has short a.

Each vowel has a short sound. E says /e/ in bed. I says /i/ in pig. O says /o/ in hot. U says /u/ in cup. Learn these five and you can read hundreds of words.

Here is the rule. A word with one vowel in the middle usually says the short sound. Cat. Bed. Pig. Hot. Cup. Consonant, vowel, consonant. Say the sounds and blend.

Words to know
short sound
the sound a vowel makes in a short word, like /a/ in cat
Check yourself

1. What sound does a make in cat?

2. Which word has short i?

3. A word has one vowel in the middle, like hot. What sound does the vowel say?

2.5

Two Letters, One Sound

Main ideaSome letter pairs, like sh, ch and th, make one new sound together.

Look at ship. Four letters. But only three sounds. The letters s and h work as a . Together they say /sh/. Put your finger to your lips. Shhh. That is the sound.

Other teams do this too. C and h say /ch/, like in chip. Say it. Your tongue clicks. T and h say /th/, like in thin. Your tongue pokes out a little.

When you see sh, ch or th, do not say each letter. Say the team sound. Fish. Chop. Bath. Look for the teams, and the words get easier.

Words to know
team
two letters that make one sound together, like sh
Check yourself

1. What sound do s and h make together?

2. Which word has the /ch/ sound?

3. Ship has four letters. How many sounds does it have?

2.6

The Silent e

Main ideaAn e at the end of a word makes the vowel say its name.

Look at cap. Short a. /cap/. Now add an e to the end. Cape. The a changed! Now it says its name, ay. And the e says nothing at all. It is a .

The silent e is a helper. It sits at the end. It makes no sound. But it tells the vowel to say its name. Kit becomes kite. Hop becomes hope. Cub becomes cube.

Watch for the e at the end. Cover it with your finger. Read the short word. Then let the e back in. Say the vowel’s name. Pin. Pine. You can hear the change.

silent e
an e at the end of a word that makes no sound but changes the vowel

Read Left to Right

Main ideaRead the letters in order from left to right, and you get the right word.

Look at the word pat. Point to the p. That is the side. Now slide your finger to the right. P... a... t. Pat. You read the letters in order.

Order matters. The letters t, a and p can spell tap. Or pat. Or apt. Same letters, different words. Start on the left. Go to the right. Then you get the right word.

Lines work the same way. Read a line from left to right. When you reach the end, jump down. Start again on the left. Your finger can lead the way.

Words to know
left

1. Which side do you start reading on?

2. Read these letters in order: p, a, t. What word is it?

3. What happens when you reach the end of a line?

2.8

Write the Letters in Order

Main ideaThe alphabet has 26 letters in a set order, and you can write each one.

Start at the top. Pull down. Lift. Cross. That is a t. Every letter has a way to be made. Start at the top for most letters. Sit the letter on the line. Make small letters small.

All the letters together are the . There are 26. They go in an order. A, b, c, d, e, f, g. The order never changes. The song you know puts them in a row.

The order is useful. Names on a list go in alphabet order. Books on a shelf go that way too. Write a, b and c on a paper. Then keep going. Can you get all the way to z?

For the teacher

Every lesson keeps its own three checks; a lesson is ticked when all three are right. Chapter reviews, the unit test and its spiral review (five questions from earlier units in this band) score on the page. When the site is connected to your sheet, or the link carries ?dest=, each one also has a Send box: the first-try score, the standards, the supports used, the attempt number and the minutes go to your sheet as an IEP data point.

Print this page for a paper copy of the readings, the sources, the words and the questions; the answers print as dashed boxes under each question.

Fact-check notes for this course live in the handoff: quotes marked (paraphrased) were set that way on purpose.
