Explicit Phonics Lesson
Digraph ch, -tch
Day 1
Objective: Sound and blend words using the digraph ch.
Review: We have learned that two letters that
work together to make one sound are called a digraph. What digraph have we
studied that has the /k/ sound? –ck When is the –ck spelling used? After a short
vowel at the end of a word or syllable. What is a digraph? Two letters that work together to
make one sound. What other digraphs have we studies?
Sh, th, -ng
Today we are going to study a new digraph. Show the Cherries
picture card. C and h come together to make the /ch/
sound. When we chomp on cherries we have to chew.
The sound of ch is /ch/ as in chomp, cherries, and chew. It is an unvoiced,
puff of air coming out of the mouth quickly.
There are two
spellings on the Cherries card. The other spelling for /ch/ is –tch. There is a
dash in front of the -tch because it comes at the end of words and never at the
beginning. The –tch is also like –ck because it is often, (but not always), the
spelling we use after a short vowel sound.
What do
we call two consonants that work together to make one sound? digraph
What
sound does the digraph ch make? /ch/
Is /ch/ a voiced or unvoiced sound? unvoiced
Is /ch/
a stream of air or a puff of air?
puff
What are
the spellings for the Cherries sound?
ch and -tch
PA (oral)
Listen to
these words and see if you can hear the digraph /ch/ or not. If you hear the /ch/
sound in the word, I want you to give me a thumbs up. If you don’t hear /ch/ in
the word, give me a thumbs down. So if I say chin, /ch/ /ĭ/ /n/, you would give me a thumbs up because the /ch/ sound
is in the word chin. If I say kit, /k/ /ĭ / /t/, you would give me a
thumbs down because you do not hear /ch/ in the word kit.

Decoding
Use the decoding procedure as in
previous lessons. Take time to talk
about the meanings of any words that might be unknown.
chick chimp match chest
chill chip check pitch
rich fetch catch chalk
Some clues might
be:
1. to look at something to see if it is right check
2. antonym for heat chill
3. put things
together that go together match
4. synonym for throw pitch
5. to go get and
bring back fetch
6. the front,
upper part of your body chest
7. synonym for
monkey chimp
8. antonym for
poor rich
9. a broken off
piece of something chip
10. used to write
with chalk
11. a baby
barnyard fowl chick
When there is only one word left (catch), have the buddies read the last word. Each
buddy then uses the word in a sentence
Decodable Text
Practice reading words in text using
the decoding practice.

I am going to
say some words with the /ch/sound. I want you to tell me if the sound is at the
beginning or the end of the word. If I say much,
you would tell me the /ch/ is at the end of the word. If I say chick, you would tell me the /ch/ is at
the beginning of the word. Be sure your Buddy agrees with you before you raise
your hand to give me your answer. (Segment words if needed.) Where is the /ch/ sound in the word church? At the beginning and the end

sentences (7 or more words in the sentence.)
Decodable Text
Use ch phrases to practice phrase reading. The first time through have
them follow as you read. The second time, have them chorally read with you.
Then the Buddies can take turns reading to each other.
