Learning to read is a complex task. Just as the kid masters single sounds, we introduce digraphs, where two letters make one sound. Digraphs are sounds like sh, ch, th and ee. The kid could name digraphs when they were listed, but didn’t always spot one when it was hidden inside a word. I wanted an activity where they had to locate the digraph within a word. After the success of an earlier sticker-scratching reading game, I decided to use the same scratch-off stickers to make Robot Digraph Scratch.
A quick name note. Scratch here is the verb. The activity has nothing to do with the children’s coding platform of the same name. The whole thing runs on a coin and a stack of peel-off silver stickers.
You’ll need card stock in four colors (one white, three bright; yellow, red and green is what I used), a black felt-tip pen for outlining, a regular black pen for the eyes and the digraph letters, scissors, a phonics word book or any digraph word list, scratch-off stickers in the silvery peel-and-rub kind, and a small coin. The flat edge of a coin works better than a fingernail or a pencil tip. The kid does not bend the card while pressing, and the rubbing goes faster.
The build, start to finish
I picked six digraphs the kid didn’t always recognize. You can use whichever digraphs your child needs to work on.
Draw a simple robot shape onto card. Cut it out and use it as a template to create six robots on white card. Outline each one with the felt-tip pen and add eyes and a mouth with the regular pen. Write each digraph in the middle of the chest. I focused on ai, ea, oa, er, oi and ou.
Repeat with red, green and yellow card to make about thirty more robots. These are the word robots. Outline them the same way, eyes and mouth, and then write one word inside each chest.
I used a phonics word book to decide which words to use for each digraph. I wanted the words to only contain one digraph. The list I used:
ai – rain, jail, tail, afraid, paint
ea – meat, beat, heap, cream, team
oa – boat, goal, toad, float, soap
er – fern, hotter, winter, river, number
oi – coin, boil, foil, point, join
ou – out, loud, sour, count, found
Cover each word with a scratch-off sticker. Cut around the robots so you are ready to play the game.
Coin in hand
I placed the six white digraph robots in a line and put five or six colored word robots in a stack underneath. Thirty in one pass overwhelms the kid and the silver dust ends up across the carpet. Five or six is the right batch size, and you can refill the stack after each round.
I gave the kid a small coin. The kid used the coin to scratch away the surface of the sticker. The rubbing developed fine motor skills and the small hand muscles. After a lot of pressing, the hidden word came through.
The kid sounded out the word and blended the sounds together to read it. They identified the digraph hidden in the word and found its matching robot. They then placed the colored robot above the white digraph robot. They continued the game with another robot.
When a word resists, I cover the digraph again with a strip of tape and ask the kid to sound out the rest first. Then I lift the tape on the digraph last. It reframes the digraph as a single chunk rather than two letters fighting each other.
The kid loved the anticipation of trying to work out the hidden word. With each rub, a little more of the word came through.
Because I made so many robots, the activity lasts for some time. The same setup works for trigraphs (three letters that make one sound) or even split digraphs.
Stretching past the six
The same setup carries through several rounds of phonics practice with small swaps:
- Trigraphs. Three letters, one sound. Switch the chest letters on the white robots to igh, air, ear, ure. Word list shifts: high, sight, night for igh; pair, hair, stair for air.
- Split digraphs. The trickier ones where the digraph wraps around a consonant: a_e, i_e, o_e, u_e. Words like cave, slime, hope, cube. The kid scratches the word and then circles the two letters that make the long-vowel sound across the consonant. The robots help slow this step down.
- Beginning blends. Switch the chest letters to bl, gr, sp, st and pick blend words. The match-the-chunk mechanic carries.
- Sight words. Same robots, no digraph rule. Sticker covers a tricky high-frequency word (was, the, said, friend), the kid scratches, reads, and reads it aloud three times before scratching the next one.
Keep the scratched-off robots in a small tray after the session. They store flat, the kid can read them back to a parent or grandparent later in the week, and the activity earns a second round of reading practice with no extra prep.
