The problem?
Making and organizing flashcards is annoying… unless an app does the heavy lifting for you.
That’s where Flashrecall comes in:
You can instantly create letter S flashcards from images, text, audio, PDFs, even YouTube links – and it automatically builds in spaced repetition and active recall so the learning actually sticks.
Here’s the app:

Let’s walk through how to use flashcards to teach (or learn) the letter S in a fun, smart, and zero-overwhelm way.
Step 1: Decide What You Want Your “S” Flashcards To Do
“Letter S flashcards” can mean different things depending on your goal:
- Letter recognition
- Just the letter: `S` / `s`
- Matching uppercase and lowercase
- Sound awareness (phonics)
- /s/ as in sun
- /z/ sound from letter S as in nose (for later levels)
- Vocabulary building
- S words with pictures: sun, snake, sock, sandwich, star, soap, etc.
- Early reading practice
- Simple CVC words with S: sat, sit, sip, sap, bus, gas
You don’t need to do all of these at once.
Pick your main goal:
> “Right now, I just want them to see S and say the /s/ sound.”
Once you’re clear on that, your flashcards become way more focused and effective.
Step 2: Build Simple, Clean Letter S Flashcards (The Smart Way)
You can absolutely cut out paper and draw little suns and snakes. But if you’re busy (or want everything in one place on your phone), using an app like Flashrecall will save you a ton of time.
Option A: Old-School Paper (Still Works!)
For basic cards:
- Card 1: Big S on the front, “S says /s/ as in sun” on the back
- Card 2: Big s (lowercase), same idea
- Card 3+: Add picture cards:
- Front: Picture of a sun
- Back: “sun – starts with S – /s/”
Keep the design super clean:
- Big letters
- High contrast (black on white)
- One idea per card
Option B: Use Flashrecall To Make Them In Minutes
With Flashrecall, you can make digital S flashcards that actually remind you to review at the right time.
Here’s a simple setup:
1. Letter recognition deck
- Card front: `S`
- Card back: “Letter S – says /s/ like sun”
- Another card: `s` (lowercase)
2. S words with pictures deck
- Upload or screenshot images of: sun, snake, sock, sandwich, star, soap, sea, snow, etc.
- Let Flashrecall auto-generate flashcards from images
- Edit the back: “sun – starts with S – /s/”
3. Sound deck
- Record yourself saying “/s/”
- Use audio flashcards in Flashrecall:
- Front: play the sound
- Back: “S – /s/ – like sun”
Flashrecall can make cards from:
- Images
- Text
- Audio
- PDFs
- YouTube links
- Or just stuff you type manually
And it works on iPhone and iPad, even offline, so you can practice anywhere.

Step 3: Teach The Letter S Sound With Active Recall
The magic isn’t in the cards.
It’s in how you use them.
Active recall basically means: don’t just show the answer – make the brain try first.
Here’s how to do that with letter S:
Simple Routine (2–5 Minutes)
1. Show the letter S card
- Ask: “What letter is this?”
- Ask: “What sound does it make?”
2. Show picture cards
- Show a picture of a sun
- Ask: “What is this?” (sun)
- “What sound does it start with?” (/s/)
- “What letter makes that sound?” (S)
3. Mix it up
- Show `S` and `M` and ask: “Point to the one that says /s/.”
- Show `s` and `a` and ask: “Which one is letter S?”
Flashrecall automatically keeps track and reminds you of the cards you don't remember well so you remember faster. Like this :
In Flashrecall, every flashcard session is built around active recall:
- It shows you the front
- You try to remember
- Then you tap to reveal the answer and rate how easy or hard it was
The app then adjusts how often you see that card using spaced repetition so you don’t forget.
Step 4: Use Spaced Repetition So S Actually Sticks
Most kids (and adults) forget new letters if they only see them once or twice.
Spaced repetition is the trick that fixes that.
Instead of:
- Cramming S 20 times in one day and then never again
You do:
- A little bit today
- A little tomorrow
- Then again in a few days
- Then again next week
Flashrecall does this automatically:
- You study your S flashcards
- You say whether each card was easy, medium, or hard
- The app schedules the next review at the perfect time so you see it right before you’d normally forget
No calendar. No sticky notes. No “oh shoot, we haven’t practiced S in a week.”
You just:
- Open the app
- Do the cards it suggests
- Done in a few minutes
Plus, you can turn on study reminders, so your phone nudges you:
“Time to review your Letter S deck.”
Step 5: Make Letter S Practice Fun (Not A Chore)
Kids learn faster when it feels like a game.
Here are some fun ways to use your S flashcards:
1. S Treasure Hunt
- Show the S card
- Ask: “Can you find something in this room that starts with S?”
- sock, spoon, shoe, sofa, soap
You can then take photos of those real-life items and turn them into new Flashrecall cards.
Now your deck is personalized: your socks, your spoon, your sofa.
2. “Does It Start With S?” Game
Make a deck in Flashrecall with:
- Front: picture (sun, cat, snake, ball, star, dog, sock, apple…)
- Back: “Yes – starts with S” or “No – does not start with S”
Ask the learner:
- “Does this start with S?”
- They answer first
- Then flip to check
You’re training both sound awareness and vocabulary.
3. Silly S Sentences
Once they know a few S words, make a “silly S sentence” deck:
- Front: “Make a silly sentence with: sun, snake, sock”
- Back: Example: “The snake wore a sock in the sun.”
You can keep all these prompts in Flashrecall as text cards, so you never run out of ideas when you’re tired.
Step 6: Level Up – From Letter S To Reading S Words
When the learner is comfortable with S, you can use flashcards to move into early reading.
Start With Simple Words
Create cards like:
- Front: `sat`
- Back: “/s/ – /a/ – /t/ – sat”
- Front: `sip`
- Back: “/s/ – /i/ – /p/ – sip”
- Front: picture of a bus
- Back: “bus – ends with S – /s/ at the end”
In Flashrecall, you can:
- Type these words manually
- Or paste them from a list or PDF and let the app auto-generate flashcards
Because Flashrecall has built-in spaced repetition, these new reading words get reviewed at smart intervals too – not just the basic letter S.
Step 7: Use Chat To Go Deeper (For Older Kids Or ESL Learners)
If you’re using S flashcards with:
- Older kids
- Teens
- Adult English learners
You can go beyond simple letter drills.
Flashrecall lets you chat with your flashcards.
So if you have a deck of S words (science, system, support, strategy, symptom, etc.), you can:
- Ask the chat: “Give me example sentences for the word ‘support’.”
- Or: “Explain the difference between ‘sea’ and ‘see’.”
- Or: “Give me 5 more advanced S words related to business.”
This turns a simple letter S deck into a mini tutor for:
- Vocabulary
- Pronunciation
- Usage
Great for languages, exams, school subjects, university, medicine, business – literally anything that uses S-heavy vocab.

Frequently Asked Questions
What's the fastest way to create flashcards?
Manually typing cards works but takes time. Many students now use AI generators that turn notes into flashcards instantly. Flashrecall does this automatically from text, images, or PDFs.
Is there a free flashcard app?
Yes. Flashrecall is free and lets you create flashcards from images, text, prompts, audio, PDFs, and YouTube videos.
How do I start spaced repetition?
You can manually schedule your reviews, but most people use apps that automate this. Flashrecall uses built-in spaced repetition so you review cards at the perfect time.
What is active recall and how does it work?
Active recall is the process of actively retrieving information from memory rather than passively reviewing it. Flashrecall forces proper active recall by making you think before revealing answers, then uses spaced repetition to optimize your review schedule.
