The capital S and the small s, one drawing twice
The S is one of the few letters that does not change shape when it goes small: the s is the capital again, curve for curve, only shorter. So the pair sheet here draws both at their true heights rather than blowing each one up to fill its box, and the size is left to do the work. The last two sheets put the S among the shapes it gets muddled with and inside the alphabet it belongs to.
Uppercase bubble letter S
The capital S at full page size. It is one closed curve with no corner anywhere on it, so a crayon can go the whole way round without once having to stop and turn.

Lowercase bubble letter s
The small s at page size. It is the capital again, curve for curve, only shorter, which makes this the one letter on the wall chart nobody has to learn twice.

Bubble S and s together
Capital and small in matching boxes, drawn at their true heights instead of blown up to fill the page, so the only difference between the two S is the one that really exists.

Find and colour every S
Forty eight bubble shapes in a grid and only some are S. The rest are what it gets muddled with: a C, a G, a J, a Z and the number 5, which is a backwards S with a lid on it.

Where the S sits in the alphabet
The S sits late in the alphabet with the R in front of it and the T behind, and the strip underneath marks its cell, so the letter has a place on the wall and not only a shape.
Download PDFEight ways to draw a bubble S
The same S with eight finishes, every one of them printed on the sheet rather than described. Five arrive already filled with a pattern to colour between, and because the letter is turning under the pattern the whole way down, no two rows of dots or squares sit against the outline the same way. The other three change the border itself: a double line, a hard drop shadow and the fat graffiti version.
Polka dot bubble S
Open circles run the length of the S, up round the top curve and back down the bottom one, so the colouring job is the gaps between the dots and never one flat band.
Download PDF
Striped bubble S
Diagonal bands cross the S at a fixed angle while the letter underneath keeps turning, so no two stripes meet the outline the same way. Two shades finish the page.
Download PDF
Checkered bubble S
A chequerboard printed inside the S. The letter curves away under the pattern, so the squares near the two tips arrive as thin slivers and are the ones that take real care.
Download PDF
Star filled bubble S
Outlined five pointed stars scattered down the S, ready to take one shade while the letter behind them takes another. They thin out at the waist, where the curve crosses over.
Download PDF
Heart filled bubble S
Small hearts printed all the way through the S, the version that ends up on a card, a scrapbook page or a party banner rather than pinned to a classroom display board.
Download PDF
Double outline bubble S
Two lines follow the S round with a white channel between them. On a letter this curved the channel is the hard part: it has to keep one width through both of the bends.
Download PDF
3D bubble S with a shadow
A solid grey copy sits behind and below the S and lifts it off the paper. The shadow follows the same double bend, so the pair reads as one thick letter instead of two thin ones.
Download PDF
Graffiti style bubble S
The heavy version: a fat black border with a white line cut through the middle of it and a hard shadow behind, the shape an S takes when it is sprayed at the end of a name.
Download PDFTracing the S, and getting it the right way round
Dotted outlines for a pencil to follow, from one page filling S down to rows of small ones on three-line guides with a green dot marking where to start. Then three sheets that stop handing the outline over: a grid of twenty S with some of them mirrored to catch, a freehand S in an empty box, and the four steps that turn a plain letter into a rounded one.
Dotted bubble S to trace
A page sized S printed as a dotted line instead of a solid one. One trip round it teaches the direction: back to the left at the top, down through the middle, left again at the foot.
Download PDF
Trace rows of capital S
Sixteen capitals on four sets of guides, one worked and fifteen dotted. Watch the balance rather than the height: the lower curve has to come out the wider of the two every time.
Download PDF
Trace rows of small s
The same four rows with the small s, and there is nothing new to learn to do them: it is the capital again, sitting between the baseline and the dashed line instead of the top one.
Download PDF
Trace Ss pairs
Capital and small traced as one unit, twelve pairs in all. Set next to each other the two make it plain that the size is doing all of the work, because the drawing does not change.
Download PDF
Trace the S, then draw it
Half the page gives a dotted S away and the other half is an empty box. A curve with no corner in it is easy to follow and surprisingly hard to invent, which is what the box is for.

How to draw a bubble S in four steps
Four panels: the plain S, a rounded line drawn around it, the skeleton rubbed out, the letter filled in. Step two is where the two ends of the curve turn into soft round tips.
Download PDF
Which S are the right way round?
Twenty S in a grid and some of them are mirrored. The rule that sorts them out fits in one line: the top end of an S finishes on the right and the bottom end on the left.
Download PDFHow many S to a page
One child colouring one letter wants the whole sheet. A class spelling out a display wants twelve to a page. These five print the S at two, four, six and twelve to the sheet, plus a mixed page that alternates capital and small. The S is a narrow letter, so it stays tall further down this list than a wide one would and it leaves white paper either side of itself for a name.
Two bubble S on one page
Two capitals stacked on one sheet. The S is a narrow letter, so even at half a page each one stays tall, and the pair fills the paper from the top edge to the bottom.
Download PDF
Four bubble S on one page
A two by two block of capitals that cuts down into four cards. A narrow letter leaves white paper either side of itself, which is where a name or a number goes on a card.
Download PDF
Six bubble S on one page
Six capitals in three rows, one print for a whole table of children, and still tall enough that the two curves keep the size difference that holds an S upright.
Download PDF
Twelve small bubble S
Twelve to the sheet, the density a display board needs. Almost every plural ends in this letter, so a wall of words needs more S than anything else and this page gets printed twice.
Download PDF
Eight S and s in a grid
Eight boxes alternating S and s at their true heights. The same drawing in every one of them, two sizes, which turns the page into a lesson about height and not about shape.
Download PDFCut it out, hang it up, label things with it
The sheets that end up on a wall. The cut-out template prints the S inside a grey band so the scissors have something to follow, and since this letter has no hole in the middle one trip round the outside finishes it. The pennants string into a banner, the labels take a name beside the initial, and the framed monogram is a door or locker sign. Cardstock rather than copier paper for all six.
Cut out bubble S template
A stencil sized S inside a thick grey band for the scissors to follow. This letter has no hole in the middle of it, so one trip round the outside is the whole cutting job.

Bubble S pennant flag
One triangular flag with the S on it and both string holes already marked. A narrow letter on a wide flag, so it sits high and centred where the cloth is at its widest.

Three S bunting flags
Three smaller pennants on one sheet. A word strung across a wall usually wants this letter at the end as well as somewhere in the middle, so one print of this page rarely goes to waste.

S name labels to cut out
Four label cards, the bubble S on the left and a ruled line for the rest of the name. With a Sofia, a Sam and a Sara in the room, this is the label sheet that runs out first.

Framed S monogram door sign
The S centred inside a double frame with a writing line under it, printed portrait for a bedroom door or a locker. Being a narrow letter, it leaves the frame plenty of air around it.

Six S cards with cut lines
Six S boxed in dashed lines rather than solid borders, so the page tears down into six cards without a ruler. Sound sorts, snap games and a wall alphabet all want them loose.
Download PDFWords that start with S
A letter sticks when it belongs to a word. Five words, each printed once in big bubble outline to colour and twice more on handwriting guides to write. The sixth sheet is the one only this letter earns: an S on the end of a word is what turns one of a thing into more than one, so three words are printed alone and then again with the S added.
Bubble letters: SUN
SUN in bubble outline and twice more on guides. Three letters is the shortest word here, so the type comes out as big as this page ever gets and suits the youngest hand.
Download PDF
Bubble letters: STAR
STAR printed once big and twice on lines. The S and the T meet at the front with almost no gap between them, and that pair decides whether the whole word looks even or not.
Download PDF
Bubble letters: SNAKE
SNAKE is the word this letter is taught with nearly everywhere, and the reason is the shape: an S laid on its side is the animal, and the sound it makes is the hiss.
Download PDF
Bubble letters: SOCK
SOCK in fat outline letters, four wide, with a round O and a C in the middle so the colouring stays curved the whole way across instead of settling into straight walls.

Bubble letters: SCHOOL
SCHOOL is six letters, the longest word here and the one that goes up on a classroom door in September. The double O in the middle gives the page its two biggest shapes to fill.

One S at the end makes it many
Three words printed twice, once alone and once with an S on the end: sock and socks, star and stars, snake and snakes. That one letter is the whole difference.

Try the bubble letter generatorHow do you draw a bubble letter S?
Draw a plain capital S lightly in pencil. Trace a rounded line a finger's width outside the whole curve, keeping the gap even as the line swings one way and then back the other. Round both ends into soft tips, rub out the pencil inside, and colour what is left.
The S has no corner to round off
A bubble M is five points that all have to be softened. A bubble A is a triangle with a hole in the middle to defend. The S has neither: no corner, no straight edge, nothing trapped inside it, just one line that changes its mind halfway down and comes back the other way.
That makes it the easiest bubble letter to outline and the hardest one to balance. The two curves have to answer each other. Draw the top one as big as the bottom one and the letter looks like it is toppling forward; draw the bottom one too small and the whole letter stands on a point. On every sheet here the top curve is a little tighter than the bottom one, which is how the shape has always been drawn, and copying it is quicker than explaining it.
It is the letter children write backwards
The S is reversed more often than almost any other letter, and there is a reason for it: a mirrored S still looks like a letter. Nothing about a backwards one is visibly broken, so a child who draws it that way gets no warning from the page.
One sentence fixes it. The top end of an S finishes on the right, and the bottom end finishes on the left. Look at any S on this page and it is true. The right-way-round sheet in the tracing group prints twenty of them with some flipped, and that sentence is the whole method for sorting them out.
The capital S and the small s are the same drawing
Most letters change shape when they go small. A capital A becomes a circle with a stick beside it, and an M and an m are two different drawings that share a name. The S does not do that. The small s is the capital again, curve for curve, only shorter, which makes this one of the few letters nobody has to learn twice.
Two sheets are here to prove it rather than say it. The pair sheet draws both at their true heights instead of blowing each one up to fill its box, so the size difference is the only difference there is, and the mixed grid alternates them the same way.
One S at the end makes it many
The S is the letter that counts. One sock, two socks. One star, a sky full of stars. More English words end in this letter than in any other, because nearly every plural and half the verbs in the language finish with it, which means a child who can write an S can change the meaning of every naming word they know. The one-and-many sheet in the word group is built on exactly that: three words printed once alone and once with the S added.
Print them in this order
Start with the dotted S. It hands over the outline and asks only for a pencil that follows it. Then the plain capital, then the small letter, then the pair sheet that shows how much shorter the small one really is.
The patterned sheets come next. They are not decoration: colouring between printed dots or stripes needs a steadier hand than filling a plain letter does, and a child who is bored of the outline will keep going for the chequerboard.
Leave the right-way-round hunt until the tracing rows come out even, then the four step how-to sheet, then the empty box on the trace-and-draw page. Drawing a bubble letter from nothing is the last skill on this page, not the first.
The cut-out template, the pennants and the labels belong to the grown-up with the scissors, and they want card rather than copier paper. The word pages sit at the end because they are the reason to learn the letter at all.
All 37 sheets in six groups
The page is split into six: the capital and the small s with the shapes they get muddled up with, eight finishes for the same letter, the tracing sheets and the backwards hunt, the pages that print two, four, six or twelve S at a time, the cut-out and display crafts, and five words that begin with S.
Everything prints on US Letter and A4 from the same PDF, in black and white, with no sign-up and no watermark. Print one, print all 37, use them with one child or with a whole class.
More bubble letters and more letter practice
Every other letter of the alphabet, both cases, the numbers and the ready-made word banners are on printable bubble letters A-Z. The first letter of all is worked the same way on bubble letter A sheets, and the one with the most corners to round off on bubble letter M sheets. For a whole name or a word rather than one letter, type it into the bubble letter generator below. If it is handwriting you are after rather than lettering, this letter is drilled properly on alphabet tracing worksheets and joined up on cursive alphabet worksheets.
