What are these missing letter activities?

Each activity shows a picture and a word with one letter taken out, such as C _ T, B _ S or D _ G. Your child looks at the picture, says the word slowly, listens for the missing sound and taps or writes the correct letter. It is a small step, but it joins three big ideas together: the letter shape, the letter sound and the whole word.

There are two activities on this page. Find the Missing Letter – 3 Letter Words uses short, familiar CVC words that beginners can sound out. Missing Letter Animal Words for Kids uses animal names children already love to say, which keeps older learners interested while they practise longer words. Both work online and as free printables.

Skills children learn

Letter recognition: spotting the difference between b and d, p and q, m and n.
Phonics and listening: hearing the beginning, middle or ending sound in a spoken word.
Early spelling: understanding that words are built from letters in a fixed order.
Vocabulary: learning new picture words, especially animal names.
Focus and thinking: checking an answer instead of guessing quickly.
Pencil control: writing the missing letter neatly inside the box on the printed sheet.

Because each puzzle is short, children finish with a feeling of success. That small win matters a lot for a child who is just starting to read.

How to play online and how to print

To play online, open an activity and let your child tap the letter that completes the word. The game gives gentle feedback, so a wrong tap is simply a chance to try again. Phones, tablets, laptops and classroom smart boards all work, and nothing needs to be installed.

To use it on paper, choose the print option and print on plain A4 paper. Printed sheets are useful for homework folders, travel days, quiet time and group work in class. Teachers can print one set per child, or print a few pages, slip them into clear folders and let children write with a dry-wipe marker so the same sheets can be reused all term.

Ideas by age

Ages 2–3: Do not expect writing yet. Sit together, say the word out loud in a sing-song voice and let your toddler point at the correct letter on screen while you name it. Two or three puzzles in one sitting is plenty. Pair the activity with alphabet flashcards so the letters feel familiar before they appear in a word.

Ages 4–5: This is the best age for three letter words. Ask your child to stretch the word out — "c-a-t" — and notice which sound is missing. Let them write the letter on the printed sheet in pencil. Mixing in letter tracing practice helps the handwriting part feel easy.

Ages 6–8: Move to animal words and longer puzzles. Challenge your child to cover the picture, read the word first and then check. Afterwards, ask them to write a short sentence using the completed word, or build new words in the word builder activity.

Tips for parents and teachers

Say the sound, not just the name: "mmm" helps more than "em" when a child is hunting for a missing letter.
Start with the first letter: beginning sounds are easiest, middle vowels are hardest. Build up slowly.
Keep sessions short: five to ten focused minutes beats a long, tiring session.
Praise the thinking: say "you listened carefully" rather than only "correct".
Use real objects: for the word CUP, hold up a cup. Young children remember words they can touch.
In class: project one puzzle for the whole group, then hand out printed worksheets for independent work.
Repeat without boredom: the same words on a new day still build fluency, so revisit old sheets.

What to try next

Missing letter puzzles sit nicely between knowing the alphabet and reading full sentences. Once your child finds them easy, keep the momentum going with activities that use the same sounds in a new way: matching letters to pictures, listening games, or rhyming word practice that trains the ear for word endings. Rotating between two or three activity types each week keeps practice fresh, and because everything here is free and printable, you can build a simple learning routine at home or in the classroom without buying workbooks.

Frequently asked questions

What age are missing letter worksheets best for?

Most children enjoy them between ages 4 and 7, once they know the alphabet. Younger children aged 2 to 3 can join in by pointing at the correct letter while an adult says the word aloud, and older children can try the animal word puzzles.

Are these missing letter activities really free?

Yes. Every activity on this page is completely free to play online and free to print. There is no login, no subscription and no payment at any stage. You only need a device with a browser, or a printer and plain A4 paper.

Can I print the worksheets instead of playing online?

Yes. Each activity has a print option that creates a clean black-and-white worksheet. Print as many copies as you need for your family or classroom. Printed sheets are handy for homework, travel, quiet time and small group work at school.

How do I help a child who keeps guessing the letter?

Say the word slowly and stretch the sounds, like "c-a-t". Ask which sound is missing before looking at the choices. Cover the options, let the child say the sound first, then uncover. This turns guessing into listening.

Which words are used in these activities?

The first activity uses short, familiar three letter words such as cat, bus, sun and dog. The second uses animal names children already know and love to say. Pictures are included, so children can work out the word even before they read fluently.

Do the activities work on a phone or tablet?

Yes. They run in any modern browser on phones, tablets, laptops and classroom smart boards. Nothing needs to be downloaded or installed. A tablet is often the most comfortable size for small hands tapping the letter choices.

What should my child practise before missing letter puzzles?

It helps if your child recognises most letters and some sounds first. Try the alphabet flashcards and the phonics sound game for a few days, then come back to missing letter puzzles.

How often should we practise?

Short and regular works best. Five to ten minutes a day, three or four days a week, is enough for steady progress. Stop while your child is still enjoying it, so the next session feels like a game rather than a chore.
