In short
- A word-guessing game with letter feedback practises spelling and letter patterns, not meaning or use.
- Choose a hidden word the class has met in its reading, so that pupils recall a word instead of testing letters.
- Karpicke and Roediger (2008) found that repeated recall, not repeated study, improved university students' memory of new words a week later.
- Add a one-minute meaning step after the word is found, because the game alone leaves meaning untouched.
Most teachers know the format from Wordle. One player hides a five-letter word. The others have six tries to find it, and after each try they learn which letters are in the word and which are in the right place. It takes five minutes, and pupils ask to play again. This article looks at what the game really practises, using research on word knowledge and on memory. It then shows how to run it as a lesson opener, on a board with no technology, and with a short meaning step at the end.
What does a word-guessing game teach?
A word-guessing game teaches the written form of words. Pupils practise spelling, notice which letters go together in English, and recall how a word they know is spelt. The game does not teach what a word means, how it sounds, or how it is used in a sentence.
Nation (2013) divides knowing a word into three areas: form, meaning and use. Form covers how the word sounds, how it is written and the parts it is made of. Meaning links the form to an idea. Use covers the word's grammar and the words that usually go with it. Each area has a receptive side, recognising, and a productive side, producing. A guessing game with letter feedback works almost entirely on written form.
| Area of word knowledge | Practised by the game? | Why |
|---|---|---|
| Written form (spelling) | Yes | Every guess must be a real word, spelt correctly. |
| Letter patterns | Yes | Feedback shows which letters sit together and where. |
| Recalling a known word | Yes, if the word has been met | Part-filled boxes act as a cue to memory. |
| Spoken form | Only if you add it | Ask pupils to say each guess aloud. |
| Meaning | No | A pupil can solve the puzzle without knowing what the word means. |
| Use (grammar, collocation) | No | The word appears alone, not in a sentence. |
This is not a weakness once you know it. Spelling is part of knowing a word, and a pupil who can write coast correctly has learnt something real. The problem starts only when the game is counted as vocabulary teaching on its own.
Why the hidden word should come from the class reading
If pupils have never met the hidden word, they have nothing to recall. They test letter combinations until the feedback changes colour. They can reach the answer and still not know that it is a word.
If the word comes from a story the class has read, the game changes. Three letters in place become a cue. A pupil thinks of the lighthouse story and recalls coast. That act of pulling a word out of memory is what psychologists call retrieval, and it is well studied.
Karpicke and Roediger (2008) had university students learn 40 Swahili-English word pairs. Once a pair had been recalled correctly, studying it again made no difference to recall a week later. Being tested on it again made a large difference. Roediger and Karpicke (2006) found the same pattern with prose passages. Undergraduates who recalled a passage remembered more of it after two days and after a week than those who reread it.
Barcroft (2007) worked with English speakers learning 24 new Spanish words from word-picture pairs. For half the words, a six-second pause before each word gave learners a chance to try to recall it. Those words scored higher on tests given immediately, two days later and one week later.
Two cautions. The first two studies tested university students, and none of the three used a guessing game. They support the principle that recalling a word strengthens it. They do not prove that this game does so for a ten-year-old. Our article on whether word games improve retention looks at that wider question.
What the letter feedback practises
After each guess, pupils learn one of three things about every letter. It is in the right place, it is in the word but somewhere else, or it is not in the word at all. To use that information they have to think about how English words are built.
- Which letters often start a word and which often end one.
- Which pairs travel together, such as ST, CH, EA and OU.
- Where the vowels usually sit in a five-letter word.
- Which real words fit the pattern found so far.
Classroom example
The class has read a story set in a lighthouse. The hidden word is COAST.
Guess 1: BEACH. A is in the right place. C is in the word but in the wrong place. B, E and H are out.
Guess 2: COATS. C, O and A are in the right place. T and S are in the word but in the wrong place.
Guess 3: COAST. Solved.
Teacher: "Same letters as COATS. What changed? Which other words end in ST?"
The second guess shows why a known word matters. A pupil who remembers the story moves from COATS to COAST in one step. A pupil who has never met the word has to keep rearranging letters.
How to run it as a five-minute lesson opener
- Before the lesson, choose one five-letter word from the pages the class read last. Check that it is a word you want them to keep.
- Tell the class where the word comes from: "It is in chapter two." This turns guessing into remembering.
- Take guesses from pairs, not from single pupils. Each pair agrees on a word and spells it aloud.
- Give feedback letter by letter. Keep a list of the letters that are out where everyone can see it.
- Stop at six guesses or five minutes. If the word is not found, reveal it and go straight to the meaning step.
One rule matters more than the others: every guess must be a real English word, spelt correctly. That rule is what makes the game spelling practice. Without it, pupils offer strings of letters to probe the feedback.
Bring the same word back a week later in a different activity. Our guide to spaced repetition explains how to plan that without a spreadsheet.
A version on the board with no technology
You need a board, a marker and three symbols. Draw a row of five boxes for each guess.
- A tick under a letter: right letter, right place.
- A circle: right letter, wrong place.
- A cross: the letter is not in the word.
Write each guess in the boxes and mark the symbol under every letter. Copy the crossed-out letters to a corner of the board so that nobody wastes a guess on them. Once the class knows the rules, a pupil can hold the marker and lead. You keep the word, or the pupil chooses one from the story and shows you first.
Watch double letters. If the hidden word is COAST and a pupil guesses COACH, the first C gets a tick and the second C gets a cross, because COAST has only one C. Say this rule aloud the first time it comes up.
Adjust the difficulty to the class. For beginners, write the first letter in the first box before anyone guesses. For a stronger class, allow five guesses instead of six. You can also ask each pair to explain why their guess fits the feedback so far. Their reasons show you which letter patterns they already know.
Add a meaning step after the word is found
The game ends with a correctly spelt word on the board and its meaning untouched. One more minute changes that.
- Find it. "Where is this word in our story? Read me the sentence."
- Explain it. "What does it mean here?" Accept a definition, a gesture, a drawing or a translation.
- Use it. "Give me a new sentence with this word."
Laufer and Hulstijn (2001) proposed that how well a learner keeps a new word depends on how much a task involves them with it. They named three parts of involvement: need, search and evaluation. Evaluation means comparing a word or its meanings with others to judge whether it fits a context, which is close to what step three asks for. Their paper sets out a construct for research; it does not test classroom games.
For a written follow-up, turn the sentence from the story into a vocabulary-in-context question in the next quiz.
Common pitfalls
- Unknown words. A word nobody has met turns the game into letter elimination. Take the word from the class reading, every time.
- The same three pupils. Fast spellers take over. Use pairs and take one guess from each pair in turn.
- No meaning step. Pupils leave able to spell a word they cannot use.
- Five letters only. The format leaves out most long words, including many you most want to teach. Use word-building games or word-path puzzles for those.
- Treating it as assessment. A class solving a puzzle together tells you little about what each pupil knows.
- Letting it run. After five minutes the game is taking time from reading, which is where the words came from.
How iRead handles this
In iRead the guessing game is called Think Word. Pupils guess a hidden five-letter word from the story their class is reading, in six tries, with colour feedback on each letter. The game is regenerated every 24 hours from the story's vocabulary, with no teacher setup. Every clear feeds a progress record for that word, and a word cleared on two different days is marked Mastered. Teachers see retention per word, per game and per class.
The core principle: A guessing game practises the spelling of a word. It becomes vocabulary practice only when pupils already know the word and you ask for its meaning afterwards.
See it in iRead: Think Word hides a five-letter word from the story your class is reading. Pupils have six tries, with colour feedback on each letter, and no teacher setup is needed.

Use the game for what it does well: five minutes of spelling and recall on a word from the class reading. Then spend one more minute on meaning.
Frequently asked questions
Is Wordle good for ESL students?
The format is good spelling practice. A public daily puzzle is not written for language learners, so the hidden word is often one they have never met, and then they can only test letters. A classroom version that takes its word from the pupils' own reading gives them something to recall.
What level does a word-guessing game suit?
Any class that can read and spell five-letter words. The level of the word matters more than the level of the class. Take it from a text the pupils have read at their own level, play in pairs, and keep the ruled-out letters visible for younger pupils.
How often should we play it?
We suggest five minutes at the start of a lesson, two or three times a week. It is a warm-up, not the lesson. Change the word each time, and bring earlier words back in other activities so that pupils meet them again.
Do pupils learn new words from a guessing game?
Not reliably. The game gives no information about meaning, so a pupil can solve the puzzle and still not know the word. Use it to revise words pupils have already met in their reading, and introduce new words in context first.
Can I use words longer than five letters?
Yes. On a board you can draw six or seven boxes and allow an extra guess. Longer words are harder to find, so give the first letter or name the chapter the word comes from. Keep the rule that every guess is a real, correctly spelt word.
