Book, look, good, foot: the short oo sound jolly phonics teaches sits in Group 5, the fifth sound, right alongside its trickier twin, the long oo in moon and food. Most children meet it around age five, once the sounds from Groups 1 through 4 are solid.
Because short and long oo share the same two letters, this is one of the sounds where reading in context matters more than memorizing a rule. Below is the action, honest word lists, a story, a video, and a free worksheet.

Short oo or Long oo? Telling Them Apart
To make the short oo sound, keep your lips loosely rounded and your tongue high and back, but keep it brief and relaxed, nothing like the long, tense “oo” in moon. It is the same shape as short “u”, just with rounder lips, which is why book and buck can sound alike to a beginner.
In Jolly Phonics, short and long oo share one action: pretend to be the cuckoo in a cuckoo clock, moving your head forward and back while saying “u, oo,” short then long. The easiest fix for confusing them is to try both sounds in the word and keep whichever one is actually a real word: “l-oo-k” only works as “look,” never as the long version.
Building and Blending Real Words
- Beginning: this short sound almost never opens an English word on its own; the closest matches use a “wo” spelling instead: wolf, woman, would, wolves.
- Middle: book, look, good, foot, wood, hood, brook, cook, stood, shook.
- End: nothing in English actually ends with the short oo sound; a final “oo,” as in zoo or too, always takes the long version instead.
CVC-style blending: b-oo-k → book; l-oo-k → look; g-oo-d → good; f-oo-t → foot; p-u-t → put; p-u-ll → pull.
Watch-out words: blood and flood are spelled with “oo” but rhyme with “bud,” not “book,” so let your child hear you say them before adding them to a list.
The Short oo Sound Story
“Come on, we will be late!” Sam called to his sister Oona as they hurried to the shop for their mom. At the crossing, an old man was struggling across with a heavy bag, breathing hard, “oo… oo… oo,” with every step. “Let’s help him,” said Oona, and the two children carried his bag the rest of the way. “Thank you, you two are so good,” he said, and they walked the last block home feeling proud.

Two Spellings: oo and u
Most short oo words use the double letters oo, as in book, look, good, foot, and wood. The letter u on its own can make the very same sound in a handful of common words: put, push, pull, and full. Reading these aloud side by side helps children hear that the spelling changes even though the sound does not.
Four Short Games to Play
- Sound hunt (3 minutes): find a book, a cookbook, or anything wooden around the house and say each word slowly, holding the short oo briefly.
- Sort short vs. long (4 minutes): call out book, moon, look, food, good, spoon and have your child say “short” or “long” for each.
- Cuckoo blending (5 minutes): do the cuckoo action together, then use the flashcards below to build cook, look, and book.
- Quick dictation (2 minutes): say book, look, good, and foot one at a time for your child to write, then check together.
Worksheet, Tracing GIF and Flashcard Practice
Print the short oo tracing worksheet below:
Show your child this gif and have them trace the shape in the air before picking up a pencil:
For blending, use our phase 2 and phase 3 flashcards below; first have your child recognize which cards make the short oo sound, then let them build the word alone.
Arranged correctly, those three cards spell “cook.” You can also grab the full phase 3 word list:
For a written dictation game, write out a small table of graphemes your child knows, say “hook” out loud, and let them build the word from the table using listening alone.
Before and After: Where Short oo Fits
Short oo comes right after the /ng/ sound and is followed immediately by its own long partner, the long oo sound. See the whole path in the Jolly Phonics complete guide.
Frequently asked questions
What is the short oo sound in Jolly Phonics?
It is the fifth sound in Group 5, a brief, relaxed rounded vowel heard in book, look, and good, and it shares one cuckoo-clock action with its long oo partner.
How do you say the short oo sound correctly?
Round your lips loosely, keep your tongue high and back, and keep the sound brief and relaxed rather than long and tense like the oo in moon.
How is short oo different from long oo?
They use the same two letters, but short oo is quick, as in book and good, while long oo is held longer, as in moon and food; trying both and keeping the real word usually solves it.
What age do children usually learn the short oo sound?
Most children are ready around age five, once the sounds from Groups 1 through 4 feel secure.
