Oa digraph examples, word lists, free worksheets and games for phonics teaching.
In most words, the digraph represents the same sound that’s pronounced in the example words above, which sounds like the letter name for ‘o’. In fact, some teachers describe this sound as ‘long o’.
A number of other letter combinations can also represent the /oa/ sound. For example, ow, o, oe, o-e, ou and ough in the words slow, oval, go, toe, bone, soul and dough.
The Sounds American video below explains how to pronounce this phoneme in a variety of words:
There are a very small number of words where oa represents the /or/ (ɔ:) sound; for example, in the word broad, but this is a very rare correspondence for this digraph.
Note that when the oa letter combination is followed by the letter r, as in ‘boar’ and ‘hoard’, the 3 letters act as a trigraph and they represent a different sound.
Also, in some words, such as boa and Goa, the o and a represent separate sounds, so the two letters don’t act as a digraph in these words.
It’s best to wait until children can recognise individual letters and say the sounds they represent accurately and fluently before teaching digraphs.
The oa digraph is taught in phase 3 of the Letters and Sounds phonics programme which is broadly followed in many schools in England. This phase starts in the second half of the first term in reception when children are aged between 4 and 5 years old.
Introduce the digraph by showing children how to decode and blend some simple examples of words from the word list below and then get them to read some words for you.
In addition to practising reading the words, they should also practise spelling them.
If children have trouble doing this, show them how to make the words with alphabet cards. Say the sounds as you put the cards down then shuffle the cards and ask them to make up the word again.
When you are demonstrating spelling these words with alphabet cards, put the two digraph letters down at the same time as you say the sound just once.
You can also use some online resources to provide variety. For example, Reading Bear has several presentations that include ‘oa words’…
Presentations (b) and (c) for this sound (in the dark blue section with a picture of a toad) are the most relevant. Presentation (d) also contains some good examples, but the words ‘oar’ and ‘roar’ are not really helpful because the sound is different in these words. When the letter combination ‘oa’ is followed by the letter r, ‘oar’, the three letters act as a trigraph.
The Little Learner’s video below is useful to show children how to sound out and blend some simple words containing the oa digraph…
And the video below should also appeal to young children as the popular Mr Thorne teaches Geraldine the giraffe about words with the ‘oa’ digraph:
We’ve split the lists into different sound categories in alphabetical order to help you locate words you might want to use with your students.
Initially, it can help to use words that students are familiar with, but as they get more proficient, it’s good to introduce some new words to expand their vocabulary and refine their decoding skills.

Pseudo-words Containing the oa Digraph:
Doad, Doaf, Doak, Foag, Foat, Froag, Groad, Joat, Poan, Poat, Toap, Voak.
Pseudo-words are sometimes described as non-words or nonsense words and they’re used in some phonics programmes and in the UK Phonics Screening Check.
These words are designed to assess whether children are capable of decoding words that are unfamiliar to them.
Normally, a pseudo-word will be presented next to an image of a monster or an alien, and the child is told that the word represents the creature’s name. The examples below are from the 2017 phonics screening check.
You could use some of the pseudo-words in our list as practice words for a screening check or as part of a less formal assessment of a child’s decoding ability.
Some of the words in the list might have a real meaning in some regions, groups, or sub-cultures, but they will be unfamiliar to most children so can be used alongside genuine pseudo-words.
We’ve created the following worksheets that you to download for free. Click on the headings or the images below to access these resources.
Children need to decide which pictures represent words that contain the oa digraph. They can also try to spell the words. We’ve also created a PowerPoint version of this resource if you want to display it to a class.
Each of the sentences on the worksheet has a word missing that contains the ‘oa’ digraph. Children need to fill in the missing word to complete each sentence. We’ve also created a PowerPoint version of this resource if you want to display it to a class.
Circle or write in the digraph that gives the correct spelling for each picture. We’ve also created a PowerPoint version of this resource if you want to display it to a class.
