Cluster Reduction Minimal Pairs: Frog or Fog?
Eight minimal-pair cards for cluster reduction, played as a memory game: a word that starts with two consonants against the word left when the child drops one, from frog and fog to star and tar.
How to run it
Play it as memory: turn two cards, and keep them when a target word and its partner match. Name both cards on every turn. When the student keeps a pair, they say the cluster word, and you listen for both consonants. If you hear fog for frog, point to the fog card and ask which one hops. Take turns so they hear you model the clusters too. Play the /s/ clusters and the /r/ and /l/ clusters as separate rounds if one kind is harder.
Cueing ladder
Start at the top. Add support one step at a time.
- IndependentThe student names one card of the pair; you point to the card you heard. Wait 3 seconds.Log as correct
- Listen firstSay both words of the pair, then ask the student to say the one you point to.Log as cued
- Verbal modelSay the target word slowly, stressing the sound that changes, and the student repeats it.Log as cued
- Placement cueSay the two consonants separately and slowly, f then rog, then push them closer together until there is no gap: frog.Log as cued
Adjust it
Play with the cards face up, and use only the /s/ clusters or only the /r/ and /l/ clusters.
When the student keeps a pair, they use the cluster word in a sentence, such as the frog can jump.
Matching IEP goal
Given minimal-pair picture cards, Student will produce both consonants of initial clusters in 8 of 10 opportunities across 3 consecutive sessions, given no more than a visual cue.

Eight minimal pairs for cluster reduction, the pattern where a word that starts with two consonants loses one of them. The pairs use the reductions children most often make: the /r/ or /l/ drops out of frog, bread, crab, tree and clap, leaving fog, bed, cab, tea and cap, and the /s/ drops off spin, star and snail, leaving pin, tar and nail. Each pair differs by that one missing sound.
What to listen for
Notice which clusters keep both sounds and which lose one. A student may manage /s/ clusters before /r/ clusters, or the reverse. Listen for a vowel slipped between the two consonants, as in fuh-rog, which keeps both sounds but is a different pattern. Note whether a student who drops a sound always drops the same one.
Carrying it home
Find pairs around the house: bread at breakfast, a star on a book, a picture of a frog. Say the word with both sounds a little slowly, then let the child copy. Play which one did I say with crab and cab or tree and tea. A handful of words a day, said well, is better than a long list said quickly.

Questions
- What is cluster reduction?
- Cluster reduction is a speech pattern where one consonant in a cluster is left out, so frog sounds like fog and star sounds like tar.
- Why use minimal pairs rather than practising the cluster?
- A pair shows the student that leaving out a sound makes a different word. That meaning change is the reason to keep both sounds.
- Is it free?
- Yes. It plays free in the browser with no login. An account adds session data, goal scoring and assignment to a student.
- Can I play the same pairs as a different game?
- Yes. Copy it to your own library, open the copy in the Activity Studio, and switch the template between Match Up, Memory Pairs and Find the Match. The same pairs play in each.
