Diphthong oi / oy

  

 Explicit Phonics Lesson

oi/oy

Day 1

Phonemic Awareness:

          We have been studying diphthongs. What is a diphthong? (2 vowels that work together to make a sound.) Last week we studied ou and ow. The sound of ou and ow is /ou/ as in, “Ow! I hurt my knee!” (point or show the “Hurt Knee” sound card.) Give me some words with the /ou/ sound.

          This week we are going to study the diphthong that has the “Pig” sound, /oi/. The pig makes the sound “oink”. The sound of the diphthong oi/oy is the first sound in “oink”.

          What is the “Pig” sound? /oi/

          I am going to say some words. I want you to tell me if the /oi/ sound is in the word or not. For example, if the word is boy, you would give me the thumbs up signal because the word has the “Barking Seal” sound. If the word is house, you would give me the thumbs down signal because it does not have the /oi/ sound.

          Pronounce these words to have the students indicate if the word has the /oi/ sound:

moist           enjoy           south           choice          oil            joint         toy

about           loud             annoy           load             tooth       corduroy   toil 

Spelling Generalizations:

Use oi at the beginning or in the middle of a word for the “oi” sound.

Use oy at the end of a word for the “oi” sound.

                   

Decoding:

          The sound /oi/ is usually spelled with oi when it is in the middle of the word and oy when the sound is at the end of a word. (Show the “Pig” sound card.) Use two colors of markers to write /oi/ words one spelling at a time on the board as the class sounds out and then blends the words as a group.

join              moist           toy              spoil           

point            boil              coin              voice          

oil                soil              boy              choice

joy               enjoy           destroy        avoid

                  

          After the words are decoded, briefly discuss meanings of words that may be unfamiliar to the students. Reread the lines of words with the class. Then give clues and have the students tell their buddy which word is the answer. Call on one set of buddies to give and spell the answer. Circle the words on the board as they are given as answers. Clues could be:

1.     A little wet…moist

2.    A money word…coin

3.    You use this when you speak…voice

4.    To tear something apart…destroy

5.    To keep away from something…avoid

6.    A male person…boy

7.    To ruin or go bad…spoil

8.    Something used to lubricate a car engine…oil

9.    Another word for dirt…soil

10. To be very happy…joy

11.  Something to play with…toy

12. I want to ______ the Boy Scouts this year…join

13. To heat until it bubbles…boil

14. We will ________ the movie…enjoy

15. You made a good _________...choice

The last word (point) is read by a student and used in a sentence. This exercise will give practice in reading words with the /oi/ sound and will help expand vocabulary at the same time.

Vowel Sound Chart:

          Fill in the space on the vowel sound chart for oi and oy

Reading Decodable Text:

          Have the students highlight words in the phrases that have the /oi/ sound. Read the phrases to the students, have the class read them chorally, and then have buddy A read to buddy B. Then B will read to A.

         

Day 2

Review:

          Review the definition of a diphthong (2 vowels that work together to make a sound.) Review the diphthongs already studied (/ou/ and /oi/) using the Sound Spelling cards. Be sure to refer to the sounds as the “Hurt Knee” and “Pig” sounds.

Phonemic Awareness:

I am going to say a word with the /oi/ sound. I want you to tell me if the /oi/ sound is at the beginning, in the middle, or at the end of the word.  For example, if the word is boy, you would give me the signal for the sound /oi/ being at the end of the word. Each student could use cards with B, M,  and E. Another procedure could be to use thumbs up for beginning, thumbs down for ending, and right hand between the thumb and fingers of the left hand for middle.)

          Pronounce these words to have the students indicate where in the word the /oi/ sound is heard:

soil              joy               oil                coin             ointment      toy

voice            noise            decoy           point            Roy              foil

Decoding:

          Write the following words on the board as the students sound and blend into words (see Day 1. Use buddy strategy for more student engagement.)

          hoist            soy              noise            joint

          coil              foil              Roy              royal

          cowboy         employ         decoy           rejoice

          loyal             poison          voyage         joyful

         

Use these clues or make up your own:

1.     Shiny silver colored metal sheet…foil

2.    A boy’s name…Roy

3.    A long journey made on a ship…voyage

4.    Your knee is a ________...joint

5.    To hire some to work for you…employ

6.    Wooden or plastic ducks used when you hunt…decoys

7.    Synonym for happy…joyful

8.    A bean used as a source of protein…soy

9.    Synonym for sound…noise

10. To raise something up by pulling down on a rope…hoist

11.  A dangerous substance  that could kill you…poison

12. To be faithful…loyal

13. A word used to describe a kings family…royal

14. A rope or wire wound up in a circle…coil

15. The _______ rode a painted horse…cowboy

Have a student read the last word (rejoice) and use it in a sentence.

Reading Decodable Text:

          Have student Buddies practice reading the phrases again. They should pair up and read them to each other while the teacher drops in and listens to various pairs reading. (You will need to copy one for each pair of students.)

Day 3

Review:

          Use Sound Spelling cards to review diphthongs ou, ow, oi, and oy. Have words with these spellings on flashcards (about 12) to quickly practice decoding.

Word Building:

          Using a pocket chart and letter cards or magnetic letter tiles work through the word chains:

          joy               foil               soil               voice           boil

          boy              toil               spoil             choice          broil

          coy               coil              

          soy               coin

          toy               join

Troy             joint

                    point

                   

         

Encoding:

          Use the dictation procedure.

          1.       oi          ow          oy                           

          2.       toil        boil        spoil                        

          3.       choice    voice     moist

          4.       enjoy      avoid     destroy

          5. Avoid getting poison ivy or it will spoil the trip.

Reading Decodable Text:

         Have the students highlight all the oi and oy words in the sentences and practice reading them in pairs.

Day 4

Review:

          Review quickly the definition of a diphthong, and the sounds of ou, ow, oi, and oy. Have the students give words that have these target sounds. List them on the board with the students’ help in spelling them.

“Chunking” Words:

          Write these words on the board one at a time. Circle syllables and have the students read that syllable. Once all syllables are circled, blend the syllables into words. (Always discuss word meanings when deemed necessary.)

avoid            turmoil         rejoice         destroy        voyage         moisture

appoint        tinfoil          broiler         employ         rejoice         overjoy

Reading Decodable Text:

         Have the students practice reading the phrases and sentences again using the  buddy strategy.

Day 5

Review:

          Review quickly the definition of a diphthong, and the sounds of ou, ow, oi, and oy using the sound spelling cards. Using about a dozen word cards, have Buddy A read the first word and tell a sentence using the word to Buddy B. Call on one Buddy A to share their sentence. Then for the next card, Buddy B reads and tells a sentence using the word to Buddy A. Continue until all the word cards have been used.

Encoding:

          Use the dictation procedure:

          1.       oi           ŏ          ou         oy         ō

          2.       hoist            point            noise

                                               The Lost Coin

     Roy was annoyed when he lost the coin his uncle Troy had given him for his birthday. It was in a royal blue box with a white ribbon around it. He had hoped that it hadn't been destroyed somehow. 

     Roy asked his friend Joyce to join in the search for the coin. Roy appointed her to look upstairs while he searched downstairs. As he searched, he heard her voice calling from upstairs to say that she had found it. However, it turned out to be a turquoise box, not his royal blue one. They had no choice but to continue their search.

     When Roy finally found the coin box, it had fallen in a coil of rope and was very soiled. Nevertheless, Roy was overjoyed to have his coin again. He didn't forget to thank his loyal friend Joyce for joining him in his search.
