Rainbow — a step-by-step lesson for grown-up and child
This lesson rumbles: your child switches on a growl that lasts all breath long, draws a rainbow one rrr per band, and traces a letter with a leg kicking out to the side.
What is this?
R is the eighteenth letter of the alphabet. Big R and little r make the r sound — rrr, the growl of a friendly dog, the rumble of a small engine. Start it and hold it: the sound rumbles as long as you like.
What does it mean?
R is a holdable sound, which makes it measurable: long rrrs, short rrs, growling contests. Children who struggle to hear tiny sounds often find held ones easier — R is their friend.
What does the child need to know?
The letter is called R; the sound is rrr, a growl with the voice on. Some tongues curl for it, some do not, and both are correct — the rumble is what counts, not the tongue’s style.
Why this matters
Rainbows are headline news at three, so the word arrives pre-loaded with excitement. Drawing the bands one rrr at a time stretches one word into a whole craft session of sound practice.
What it teaches
Sustained-voice sound production, sound-length control, letter recognition in two cases, crayon arc-drawing for pre-writing curves, and colour naming layered onto phonics for a two-in-one lesson.

Say this to your child
“"This is the letter R — hello, R! R says rrr — a growl, like a friendly dog. Switch your voice on and hold it: rrrrrr. Feel the rumble? Now say it with me: rrr, rrr, rainbow! And let us draw one — a growl for every band. What a colourful letter."”
Step by step
- Show the card and point up high: this is the letter R, and this is a rainbow — the sky’s most famous arc.
- Make the growl: switch your voice on and rumble — rrrrr, like a friendly dog. Hold it long, then clip it short: rrr, rrr, rainbow.
- Trace big R — tall line down, small belly at the top, then a leg kicking out — and little r: a short stick with one small shoulder.
- Draw a rainbow together: one rrr per colour band, drawn as arcs across the paper. Three bands is a fine rainbow; seven is the deluxe edition.
- End with an r-hunt: find three things that start with the growl — a red crayon, a toy rabbit, somebody’s rosy cheek — and rumble the sound at each.
Look closer at the picture
Find the big uppercase R and the little lowercase r on the card, then the rainbow and the word Rainbow. Ask which letter grew a leg — big R kicks one out from its belly, little r keeps just a shoulder.
Ask your child
"What is this letter called?" "What sound does R make?" "How long can you hold your growl?" "Which colour comes next on our rainbow?" — answered with a name, a rumbling rrr, a breath record and a colour choice.
What your child can say or do
"Rrr! Rrr-rainbow!" Expect growls at passing dogs and engines, r-sounds offered to running and rabbits, and rainbows requested on every grey day. The growl contest may need a referee. Colouring in becomes sound practice.
Out in the real world
R rumbles through the day: rain, run, red, round, room. Every growl is the card rehearsing — and every real rainbow spotted from a window or a car seat becomes the letter’s own celebration parade.
Try it together
Growl and draw: move the crayon across the paper only while the growl lasts — rrrrrr keeps the line travelling, silence stops it. One long growl makes one long band. Fill the rainbow together, one held sound per colour.
Understanding check
Ask what R says: a growl with the voice switched on and holdable length means the sound landed. A little r traced in the air — stick, then shoulder — completes the arc.
Parent tips
Both tongue versions of rrr are correct, so never correct tongue shape — rumble on. If the growl will not start, try an engine sound first; cars have been teaching this letter for decades.
Staying safe
Crayons stay on paper — walls grow their own rainbows otherwise, which is a different lesson. Growling contests pause for breath-catchers, and rainbow-spotting from windows and car seats stays seated and supervised.
This lesson pairs with the Rainbow flashcard in the library — print it, show it, keep it on the fridge. Back to Alphabet A–Z (Preschool).
