Why it works
Orthographic mapping is the process by which readers turn words they have decoded into instantly recognized sight words, and understanding it corrects one of the most consequential misconceptions in reading instruction. Many people assume skilled readers recognize words by their visual shape, memorized like little pictures, which leads to teaching sight words through flashcard drill and whole-word memorizing. The research, especially Linnea Ehri's work, shows this is wrong. Readers store words by mapping the sounds in the spoken word (phonemes) to the letters that represent them (graphemes); once a word has been decoded a handful of times with attention to those sound-letter connections, it becomes bonded in memory and is recognized instantly and effortlessly. In other words, a sight word is a decoded word that has been mapped, not a memorized picture. This explains a great deal: why strong phonemic awareness and phonics are the foundation of fluent word reading, why decodable practice matters, why guessing from pictures or context is a dead end, and why some students accumulate sight words effortlessly while others, often those with weak phonemic awareness, struggle to retain them no matter how many flashcard repetitions they get. The instructional implications are concrete: build phonemic awareness so students can hear the individual sounds, teach the sound-letter correspondences explicitly, give students practice decoding words with attention to those connections, and trust that mapping, not drill, is what turns decoded words into automatic ones. The workshop makes the mechanism clear and translates it into what teachers should do, and stop doing, so that sight-word vocabulary is built the way the brain actually builds it.

The core activity: align teaching to mapping
The heart of the session is understanding the mechanism and translating it into what to do and stop doing.
- Build phonemic awareness so students can hear the individual sounds in spoken words.
- Teach the sound-letter correspondences explicitly, and give practice decoding words with attention to those connections.
- Understand that a sight word is a decoded word that has been mapped after a few exposures, not a memorized picture.
- Retire whole-word flashcard drill and guessing from pictures or context, which do not build mapping, and support strugglers by strengthening phonemic awareness.
Facilitator notes
- Bust the shape myth explicitly; it is what drives flashcard and whole-word instruction.
- Weak phonemic awareness is why some students cannot retain sight words; strengthen it rather than drilling harder.
- Guessing from pictures or context is a dead end for word reading; name it and replace it with decoding.
Adapt it
- Elementary: this is core early-reading instruction; build PA and explicit phonics from the start.
- Secondary: striving older readers often need exactly this; weak mapping is a common hidden cause.
- Any setting: for a student who cannot retain words, check phonemic awareness before assuming more drill will help.

Orthographic Mapping: how sight words are built
Mapped, not memorized: build phonemic awareness, teach sound-letter links explicitly, practice decoding, retire flashcard drill and guessing.
- A shape-memory or flashcard habit I will replace:
- How I build phonemic awareness:
- How I teach sound-letter correspondences explicitly:
- How I give decoding practice that builds mapping:
- How I support a student who cannot retain words:
Make it stick
Word reading improves when instruction fits the mechanism. Close by setting the follow-up:
- Name a check-in: are students mapping and retaining words, not drilling them?
- Bring one habit you replaced with mapping-aligned teaching.
- For strugglers, strengthen phonemic awareness before adding drill.
