Phoneme Substitution: A Fun Way to Build Blending Skills
Phoneme substitution or letter-sound switching builds cognitive flexibility and helps young learners practice blending.
Many educators and parents ask: What can I use to help students with decoding? They know the letter sounds—so why can’t they blend them? There are many answers. However, by using these cards or a game like this, emergent readers can practice blending without being overwhelmed by multiple letter sounds.
Phoneme substitution is a crucial skill for several reasons.
The idea is they start with a whole word, such as log, and change or switch the /l/ sound to the /d/ sound. This is a game that you could play in the car or while you’re standing a line waiting. Phoneme switch has been called ‘the game you can play in the dark,” because it is just a game of switch sounds. That is what makes it a great cognitive game.
The bonus of the cards is that there is an image on the card, and the student is only changing one part of the word, beginning, middle, or end. Additionally, the image helps with vocabulary. Some words are tricky and often confused, such as pen/pin, peg/pig.
Self-checking cards have the answers on the back. The arrow at the top of the card tells the student while direction to insert the card into the chute. The chute flips the card to reveal the answer on the back. Some kids think it is magic. This set includes CVC, CCVC, & CVCC words.
You can get them from the Pure Joy Teaching TPT shop, along with other Flip Chute games. All Flip Chute cards come with the template and instructions to DIY your own Flip Chute box.
You may also be interested in encoding practice. For students who are overwhelmed by trying to put sounds and letter symbols out of the air or struggle to sort through all 26 letters of the alphabet. Scrabbled words may be your way to engage them in a can-do task.

Building Cognitive Flexibility and Supporting Reading Intervention with Uno-Style & Crazy 8 Spelling Games
These colorful, engaging card games are more than just fun—they’re powerful tools for building cognitive flexibility and reinforcing essential spelling and decoding skills. Designed in the style of popular games like Uno and Crazy 8, these four targeted spelling games support reading intervention while keeping learners motivated and engaged.
Each game focuses on a foundational spelling pattern:
CVC – Simple consonant-vowel-consonant words, perfect for early readers. Carefully selected to avoid confusing endings like “r” or “z.”
CVCC – Emphasizes ending blends and introduces nine essential spelling rules (like ck, wa, qu, double consonants, and soft c/g). Blends such as nd, mp, nk, and others are practiced with separate flashcards.
CVCe – Also known as the “Magic e” pattern, this game incorporates six spelling rules, including when o says /ŭ/ and when s sounds like /z/.
R-Controlled – Covers patterns like ar, or, ur, er, and more complex sounds like air and oar, along with homophones and tricky combinations (w+ar, w+or).
How These Games Build Cognitive Flexibility:
Cognitive flexibility involves shifting attention, adapting to new rules, and recognizing patterns—skills that are constantly exercised as players sort, match, and interpret cards based on multiple spelling rules and phonics cues. The color-coded format strengthens visual memory and reinforces sound-symbol correspondence.
Ideal for:
Reading intervention groups
Small group instruction
Independent centers
Home practice with families
Students can use these as traditional flashcards or jump into fast-paced gameplay, practicing decoding, blending, and rule application in a low-stress, highly engaging format. Wild cards representing spelling rules further deepen understanding and allow teachers to differentiate instruction with ease.
In short, these games blend play and pedagogy, making foundational literacy practice fun, effective, and flexible.
I have created some hints within the letter shapes to help remind the students of words that make the same digraph sound.
Creative Picture Embedded Hints with the Letter Shapes
Digraphs might be more complex to learn than blends, especially with all the tricky sounds, silent letters, and spelling rules. I have hidden some hints within the letter shapes to help remind the students of words that make the same sound as the digraph. Example ch – one of the sounds of ch is in chomp and chicken. The letter c has teeth to chomp or chew on the chicken leg, which is very similar to the h shape.
This is the first sound of ch, as in chicken. Some kids have it mixed up with the sound /tr/. I was very surprised by this until they explained that /ch/ is for the train picture. (oops!) Some programs have a Choo-choo train for /ch/ sound, and it was confusing the emergent readers.
There are many more clever hiding pictures with the digraphs and trigraphs in this set. Including the 3 different sounds for the ch.
These grapheme images incorporate the letter shapes with embedded images to help students recall the sounds that they make. Pictures aid phonemic sound recall and link to memory pathways.
3 Different Sounds of CH: ch, sh, k.
ch – 1 st sound ch, Letter c has teeth to chew the chicken on the letter h.
ch – 2nd sound k, Christmas tree image, letter c is a sack of gifts and letter h on the tall tree has the “sh” silent hand.
ch – 3rd sound /sh/ chef, letter c shape is uncovering the food. (French Word Origins)
3 Different gh Sounds:
gh – Ghost images laughing, thinking, and shhhh hand. (3 sounds on one card)
gh – Gh sleeping with h shhhh hand (silent) and coughing (f)
Other Digraphs:
ck – Duck image with bubbles on letter c and letter k has duck feet
th – Letter t is sticking a tongue out at the thumb image on letter h.
ph – Letter p is using a phone, and h looks like a phone.
wr – Wrench image with silent w.
tr – Covered with train tracks and a train on letter t.
and much more……

The cards can be printed with a word list on the back. Some cards have very helpful spelling tips too. Color-coded to help highlight the digraph or trigraph.
Moving emergent readers from single-letter sound recognition to multi-letter graphemes represents one of the most critical transitions in early literacy development. While single consonants and short vowels provide the baseline for CVC decoding, consonant digraphs—such as ch, sh, th, wh, ph, wr, kn, ck, and complex trigraphs—require students to process two or three letters as a single phonemic sound.
The Pure Joy Teaching Consonant Digraphs and Trigraphs Picture-Embedded Phonics set overcomes this hurdle by embedding intuitive visual sound cues directly within the graphic shapes of the letters themselves. Rather than placing an external visual next to a letter pair, these embedded mnemonics link auditory recall directly to visual memory pathways, creating an immediate scaffold for structured literacy instruction.
1. The Science Behind Embedded Digraph Mnemonics
When students encounter blends, each letter retains its individual sound. Digraphs, however, demand that the brain suppress individual letter sounds to produce an entirely new phoneme. Standard flashcards often rely on separate visual anchors placed above or beside text, forcing the reader’s eye to bounce between the letter pair and an external picture.
Embedded picture mnemonics solve this challenge by integrating the visual clue directly into the letter strokes:
Direct Neural Linking: The visual icon is fused into the letter anatomy, activating visual memory pathways alongside phonemic processing.
Cognitive Load Reduction: Eliminates visual clutter and secondary searching, allowing emergent readers to focus entirely on grapheme recognition.
Structured Literacy Alignment: Fits seamlessly into Science of Reading (SOR) frameworks, Orton-Gillingham (OG) lessons, and small-group intervention rotations.
2. Inside the Letter Shapes: Clever Embedded Visual Hints
The Pure Joy Teaching digraph set hides specific, memorable hints directly inside grapheme formations, helping students instantly recall tricky phonemes and spelling rules.
