Forms Curriculum: Codes, Graphemes, and Phoneme-to-Grapheme Mapping
- Forms uses codes (also called graphene/graphene in the session) to map sounds to written symbols in English. Codes = graphemes; graph themes = written symbols that represent sounds.
- Key terminology
- Phonemes: speech sounds (the sounds you hear in a spoken word).
- Phone names: the sounds themselves (spoken forms).
- Graphene (codes): written symbols that represent those sounds.
- Example concept
- Spoken word: “cat” contains three phonemes: /k/ /a/ /t/.
- Written word: “cat” uses three graphemes: C, A, T, each representing one phoneme.
- In Forms, “cat” has three codes (one per sound).
- How to read codes on flashcards
- Each code represents a sound (or sounds) and is tapped to track each sound.
- If a code represents multiple sounds (e.g., a two-letter code), you tap once per sound (e.g., an ea digraph can involve two sounds and is tapped accordingly).
- Quick example of a code and its sounds
- This code is S: /s/ (as in sun) and its second sound /z/ (as in shoes); the second sound is denoted by a superscript/mark above the letter when applicable. If no mark, it’s the first sound.
- Conventions for sequencing sounds
- Codes can indicate first vs. second sounds when more than one sound is possible for a letter or digraph.
- The goal is to map each sound to a grapheme (code) so learners can decode written words.
Consonants and Short Vowels (inventory summary)
- The session covers a broad set of consonant codes and their typical short-vowel contexts.
- Consonant codes assign a single or multiple sounds to letters (e.g., S has a basic sound and a secondary sound in certain contexts).
- Short vowels are introduced via simple, single-grapheme representations; they pair with consonant codes to form basic word shapes.
Long Vowels and Vowel Diagrams
- Long vowels are taught via vowel-diagram concepts where two or more letters make one sound.
- Common long-vowel patterns include two-letter digraphs or letter teams that produce a single vowel sound (e.g., A at the end, EE, EA, etc.).
- The approach emphasizes recognizing the written patterns that correspond to longer vowel sounds in words.
- Some codes include a silent letter, typically as the first letter or within a digraph.
- Example concepts mentioned:
- Certain two-letter codes where one letter is silent (e.g., in some words like right, the GH represents a historical form rather than a separate sound).
- Silent G in words such as "gnome" and "sign" (the G is not pronounced).
- Silent U in words like "guess" (U is not pronounced after G in that word).
- The idea is to teach learners that not all letters in a code correspond to a pronounced sound.
Final Three Codes for Suffixes (three-sound suffix codes)
- The session introduces three final codes used for suffixes that carry three distinct sounds:
- TI TI: used for suffixes that produce a three-sound sequence (e.g., related to the "tion"/"sh"-type sound in action).
- TICI: used for suffixes like "-tical" (as in facial) where the ending contains multiple sounds.
- V: used with suffixes as in words like "vision" and related forms (e.g., tension/vision context).
- Illustrative examples from the talk:
- Action (shows the "tion"-type ending with three sounds via the TI TI family).
- Facial (illustrates the TICI pattern associated with "-tical"-type endings).
- Tension / Vision (illustrates the V pattern for related endings).
- Purpose: these codes help learners parse and read morphologically complex words by treating the suffixes as a three-sound unit.
Quick Reference: Core Word-to-Code Mapping (examples mentioned in session)
- Cat: three codes corresponding to C, A, T mapping to /k/, /æ/, /t/
- Yes: example of a word where a multi-sound code is used (illustrative of multi-sound behavior in codes)
- Ordinary words to show digraphs and vowel patterns (e.g., oi, oa, au, etc.)
- Action, facial, and tension/vision illustrate suffix-related codes and their multi-sound behavior
Practical takeaways for last-minute review
- Codes are written-symbol representations of speech sounds; graphemes map to phonemes.
- Each sound in a word is counted as one code (tap per sound). Multi-letter codes may produce multiple sounds.
- Long vowels use digraphs and vowel-diagram patterns; short vowels are covered with basic single-letter codes.
- Silent letters are part of some codes; teach learners that some letters do not produce sounds in certain contexts.
- Suffixes can be taught as dedicated three-sound codes to simplify reading of morphologically complex words.
