Diphthongs Practice Activities
Grade 2 phonics worksheets help children read, sort, spell, and use diphthong words such as coin, toy, cloud, and cow.
Practice that builds confidence
What children learn
These Grade 2 phonics worksheets focus on diphthongs, the vowel sounds that glide within one syllable. Children practise hearing and reading patterns such as oi, oy, ou, and ow in familiar words.
The printable activities include word sorts, sound matching, spelling practice, sentence work, and short reading tasks. Each page helps children connect the sound they hear to the letters they see.
Diphthongs can be tricky because the mouth moves while making one vowel sound. In Grade 2 reading, children are ready to notice that coin and toy share the /oi/ sound, while cloud and cow share the /ou/ sound. These worksheets build that awareness before asking children to read and spell the words independently.
Skill progression
The practice moves from listening to reading, then to spelling and using words in context. Children may begin by identifying the shared sound, then sort words by spelling pattern, such as oi in the middle of a word and oy at the end. Later activities ask them to choose the correct word in a sentence, complete a spelling pattern, or read a short phrase smoothly.
A simple parent routine
Choose one diphthong sound for the day. Say three words aloud, such as coin, boil, and toy, and ask your child to repeat the sound they hear. Then have them complete one worksheet section, underline the diphthong, and read the finished words back to you. End by asking your child to make one oral sentence with a favorite word from the page.
Classroom uses
Teachers can use these pages during phonics centers, small-group intervention, morning work, or follow-up practice after a mini lesson. Word sorts work well for partner talk: one child reads the word and the other explains the category. Sentence activities are useful for connecting phonics to reading comprehension because students must think about meaning, not just the letter pattern.
Common errors to watch for
Some children confuse ou and ow with short vowel sounds, reading cloud as clod or cow as caw. Others overgeneralize, spelling toy as toi or coin as coyn. Encourage students to say the word naturally, listen for the diphthong, and check whether the spelling pattern looks right in the word position.

Why iBloom worksheets help
Each worksheet gives focused practice without crowding the page. Children see the diphthong in words, sentences, and simple reading contexts, which helps the skill transfer beyond isolated word lists. A child-friendly strategy is: “Say it, slide the sound, circle the letters, then read the whole word.”
Helpful answers
Frequently asked questions
What are diphthongs in Grade 2 phonics?
Diphthongs are vowel sounds that glide from one mouth position to another within the same syllable. Common Grade 2 examples include oi in coin, oy in toy, ou in cloud, and ow in cow.
Which diphthong patterns do these worksheets practise?
The activities focus on common diphthong spellings such as oi, oy, ou, and ow. Children practise reading, sorting, spelling, and using these patterns in words and sentences.
How can I help my child choose between oi and oy?
Have your child listen for the /oi/ sound and then look at the word position. In many familiar Grade 2 words, oi appears in the middle, as in coin, while oy often appears at the end, as in toy.
Why does my child read diphthong words incorrectly?
Children may try to read each vowel separately or replace the diphthong with a short vowel sound. Ask them to circle the vowel team, say the glide sound, and then reread the whole word smoothly.
Can these worksheets support reading comprehension?
Yes. Strong diphthong decoding helps children read words more accurately, which frees attention for meaning. Sentence and short reading tasks also require children to connect the phonics pattern to context.
