S2C lessons: Spell to Communicate lesson plans
How an S2C lesson is put together, what each of its eight question types asks for, and a complete worked example you can read end to end.
An S2C lesson is a short piece of academic content with a question set attached, written so a nonspeaking or unreliably speaking learner can answer it by spelling on a letterboard. The paragraph carries the subject and plants the words the early questions will ask for. The questions turn it into work, one letter at a time.
Spell to Communicate was developed by Elizabeth Vosseller and is taught through I-ASC. The approach treats the problem as a motor one rather than a cognitive one, which is why the lesson has to be written for the age and the interests of the person answering, not for the speed at which they can answer. A fifteen-year-old asked about farm animals learns something, and it is not about farm animals.
What a complete lesson looks like
Here is a full one, written short for a speller earlier in their motor practice. Read the paragraph first, then look at how the questions move.
PENGUINS are birds that cannot fly. They live mostly in the SOUTHERN HEMISPHERE, and the largest group lives in ANTARCTICA. A penguin's black and white feathers are called COUNTERSHADING. This coloring hides the penguin from animals swimming above it and below it. Penguins have DENSE bones. Heavy bones help a penguin sink instead of float, so it can dive deep to find food.

The paragraph is deliberately brief. Five target words in six or seven sentences is a typical density for S2C, and the words are marked so the communication partner knows which ones to stress when reading aloud. Because there are only a handful, they can be bolded as well as capitalized without the prose turning into a wall of emphasis. That is a real point of difference from Spellers Method lessons, where the paragraph runs denser and carries inline definitions.
The question set opens with two spell-only questions. Neither one asks the speller to understand anything, which is the point: the session starts on something completable. It closes on a question with no right answer. Everything in between moves gradually further from the text.
The eight question types
S2C lessons draw on a fixed set of question types. They are not labels for their own sake. Each one changes what the speller has to do before they can start pointing.
- Spell-only asks for a capitalized word from the text. Pure motor work, which makes it a warm-up and a safe place to return to.
- Known has one right answer, and it is in the paragraph. Finding it is comprehension, but the answer itself is not in doubt.
- Tight semi-open accepts a small number of short answers, all grounded in the text. The speller chooses which one to give.
- Broad semi-open asks a conceptual question where several phrasings are all correct. This is where summarizing starts.
- Numbers and math asks for a calculation, which uses a different part of the board and a different kind of attention.
- Prior knowledge asks for a verifiable fact the paragraph never gave. It is the clearest demonstration in a lesson that the speller is thinking rather than copying.
- Open-ended asks for a feeling or an opinion. No answer key, by design.
- Creative writing is a longer invitation at the end of the lesson, for spellers with the stamina for it. It is optional, and a lesson can carry more than one.
Which of these belong in a given lesson is a per-speller decision rather than a rule. A speller six months into motor practice and a speller with three years of it need different mixes of the same eight types.
Pacing, stamina, and reading level
Two things get confused with each other constantly: how hard the content is, and how much motor work the lesson demands. They are separate. You can write a paragraph about plate tectonics at a fourth-grade reading level and attach four questions to it, and that is a different lesson from the same paragraph with eighteen questions attached. Content difficulty should track reading level. Question count should track stamina on the day.
Age is the third dial, and it is the one most often got wrong. Subject matter should be something a same-age peer would be studying. Vocabulary and sentence complexity should be readable for this particular speller. Those two requirements pull against each other, and holding both is most of the craft in writing a good S2C lesson.
Writing them, or generating them
Every part of this is writable by hand, and practitioners have been doing exactly that for years. The cost is time: an hour or two per lesson, per speller, per session. That is the part that does not scale, and it is why so much of the material in circulation is either recycled or written for a much younger audience than the person using it.
SpellerLessons builds the whole structure from a topic and a speller profile: the paragraph at the right reading level, target words embedded and capitalized, and the question set across whichever of the eight types you have switched on. You keep the editing pass. What you get back is a draft with the right shape already, in a couple of minutes.

Common questions
Spell to Communicate, usually shortened to S2C, is a letterboard communication approach developed by Elizabeth Vosseller and taught through I-ASC, the International Association for Spelling as Communication. A trained communication partner holds a letterboard while the speller points out their answer letter by letter. The teaching focus is motor, not cognitive: the assumption is that the person already has things to say and needs a reliable physical way to say them. Practitioners generally work from larger stencil boards toward a single 26-letter board, and some spellers go on to a keyboard.
A short paragraph of academic content with a handful of target words capitalized inside it, followed by a question set the speller answers on the board. The paragraph does two jobs at once: it teaches the subject and it supplies the words the early questions will ask for, so those words have already been read aloud and seen in context before anyone is asked to spell them. The question set then works down in support, from spelling a word that is sitting in the text to answering something no answer key covers.
Eight: spell-only, known, tight semi-open, broad semi-open, numbers and math, prior knowledge, open-ended, and creative writing. Each asks for a different combination of motor effort and thinking. Spell-only carries no comprehension load at all. Known has a single answer sitting in the text. The two semi-open types accept more than one answer. Prior knowledge asks for a fact the paragraph never gave. Open-ended asks for an opinion. Creative writing is the one extended prompt at the end of a lesson, and it is optional.
Both accept more than one correct answer, and the difference is how much room the speller has. A tight semi-open question has a small number of short answers that all sit in the text, so a partner can check the response against the paragraph. A broad semi-open question is conceptual, and several different phrasings of the same idea are all correct. Tight semi-open is easier to score and easier to complete. Broad semi-open asks the speller to summarize rather than retrieve, which costs more thinking and usually more letters.
Enough to be worth the setup, few enough that the motor work does not outrun the stamina available. In practice that tends to mean somewhere between six and twenty questions per lesson, weighted toward the easier types early in a speller's motor practice and rebalanced later. The count matters less than the mix. Twenty questions of the same shape is a drill, not a lesson, and it exercises one skill twenty times. Question counts in SpellerLessons are set per type and saved against the speller, so the shape carries over between lessons.
As a single warm invitation, and nothing more. A prompt that specifies a length, a genre, and a three-part structure is asking a speller who spells every letter by hand to satisfy a rubric, which is a lot of motor work spent on compliance rather than on their idea. One open question, in plain language, about something in the lesson they might have a view on, is the whole job. Creative writing is optional in S2C lessons, and a lesson can carry more than one prompt or none at all.
