S is one of the first letters a lot of kids ask to write — it’s the snake letter, the one that hisses. The sound is easy to hear and fun to stretch out, which is a real head start when you’re just beginning. The shape, with its two curves facing opposite directions, takes a little more practice, and that’s exactly what these worksheets are built for.
Each letter S worksheet is a free PDF, sized for US letter or A4.
The Sounds of Letter S
S is a consonant with two main sounds. At the start of a word it almost always makes /s/, the soft hissing sound, as in sun, sock, and star. But it also makes /z/ at the end of words like rose, is, and has. For preschool and kindergarten work, focus on /s/ at the start of words. That’s the version kids hear most clearly, and it’s the one these worksheets stick to.
The /s/ sound is easy to stretch and hold. You can stretch it out, ssssun, without it breaking apart, which makes S a strong letter for beginning-sound practice. Some kids do push the tongue too far forward and lisp the /s/ for a while.
That’s common in the preschool years and often resolves on its own, so keep recognition and writing moving in the meantime.

Letter S Recognition Worksheets
The first job in letter learning is recognition — knowing the letter when it shows up. These worksheets build that skill without asking kids to write anything yet.
Best for kids not yet writing.
Letter S Coloring Pages
These low-pressure pages pair the letter with a scientist and a snail. Kids relax into the shape of S while building a visual memory of what starts with /s/.
Letter S Bubble Letter Template
Bubble letter templates turn the letter into a craft project. Kids fill the S shape with patterns, color it in, or cut it out for a wall display or alphabet banner. Uppercase and lowercase come on separate pages so each gets full-sheet treatment.
Letter S Tracing Worksheets
Tracing turns letter recognition into motor practice. The dotted strokes and arrows walk kids through how S gets drawn, stroke by stroke.
Letter S Beginning Sounds Worksheets
S makes two main sounds. The /s/ sound is the most common one and the right one to start with. These worksheets pair tracing with /s/ sound work. Kids say /s/ as they trace, then circle pictures that start with it.
All-in-One Letter S Worksheet
This single sheet pulls together everything kids have learned: recognition, tracing, beginning sounds, and letter formation. It works as a refresher, a quick check, or a final piece before moving to the next letter.
S Is for…
Twelve words starting with S. All use the /s/ sound at the start, the clearest version of S for kids to hear.
- sun
- sock
- star
- snake
- sand
- soap
- seed
- sing
- six
- sit
- soup
- sail
Read these out loud and have kids repeat them back. Stretch the /s/ at the start so the sound is easy to catch: sssun, sssock. A few of these blend S with another sound (star, snake), but the S you hear first is still the clean /s/.
No-Prep Letter S Activities
Eight things to do with the letter S using what’s already in the house or classroom.
