A partial sentence in a social story is a fill-in-the-blank line that leaves out a word or short phrase for the student to complete. Carol Gray methodology uses it to check whether the student actually understood the story, not just sat through it. In a 2024 community survey of 16 parents, school SLPs, OTs, and special educators, 94% reported spending 30 or more minutes writing a single story, so the story you build is worth confirming the student comprehends. A partial sentence does that in one line.
What does a partial sentence actually do?
It turns a passive read into a quick comprehension check. Instead of the adult reading every word, you pause at a blank and let the student supply the missing piece. Carol Gray describes two sentence structures in her methodology: complete sentences that state the information, and partial sentences that invite the student to guess the next step. The guess tells you whether the meaning landed.
What does a partial sentence look like?
You take a sentence the student has already read as a complete sentence, then remove one meaningful word. Read the story fully the first time. On a reread, turn one or two lines into blanks.
| Complete sentence | Same line as a partial sentence |
|---|---|
| When the fire alarm rings, I will try to line up with my class. | When the fire alarm rings, I will try to line up with my ______. |
| My teacher feels happy when the room is calm. | My teacher feels ______ when the room is calm. |
| If I feel worried, I can hold my fidget. | If I feel worried, I can hold my ______. |
How is a partial sentence different from the other sentence types?
A partial sentence is a format, not a sixth content type. The Carol Gray sentence types (descriptive, perspective, directive, affirmative, cooperative, control) describe what a line says. A partial sentence describes how you present a line. You can turn any of those types into a fill-in-the-blank. That is why a partial sentence does not count against your descriptive-to-directive ratio: it inherits the type of the sentence it came from.
From the same 2024 survey: "I wish I had a template I could easily customize to change the pictures of the child or parents quickly but keep the same story." A reusable scaffold matters here, because the smartest place to keep your one or two partial-sentence blanks is the same across every version of a story you build for different students.
When should a school SLP use a partial sentence?
Use it on the reread, not the first read. The first pass should give the student the full, reassuring information with nothing missing. Once the student has heard the whole story, a partial sentence on the second or third read confirms comprehension and keeps the student engaged. Social narratives are reviewed as an evidence-based practice for autistic students by AFIRM and the National Clearinghouse on Autism Evidence and Practice, and checking understanding is part of using them well.
- Read complete. First exposure is the full story, every sentence intact.
- Reread with one blank. Pause at the single most important idea and let the student fill it in.
- Add a second blank only if it fits. Cap it at two or three across the whole story.
- Give non-readers a way to respond. A picture card or a gesture counts as filling the blank.
Can a partial sentence backfire?
Yes, if you use too many. A story full of blanks reads like a worksheet and loses the calm, reassuring tone that makes a social story work. It can also feel like a test to a student who is already anxious about the situation the story describes. Keep the ratio heavily tilted toward complete sentences. The blank is a spice, not the meal.
Frequently Asked Questions
What is a partial sentence in a social story?
A partial sentence is a fill-in-the-blank line that leaves out a word or short phrase for the student to complete. Carol Gray methodology uses it to check whether the student understood the meaning of the story rather than just listened to it. It turns a passive read into a quick comprehension check.
How is a partial sentence different from a directive sentence?
A directive sentence tells the student what to try to do, such as "I will try to raise my hand." A partial sentence removes a word from a descriptive, perspective, directive, affirmative, or cooperative sentence and asks the student to supply it. Any sentence type can be turned into a partial sentence.
How many partial sentences should a social story have?
Use them sparingly, usually one to three across the whole story, placed at the key ideas you most want the student to hold onto. Too many partial sentences turn the story into a quiz and break the calm, reassuring tone.
Do partial sentences work for non-readers in kindergarten?
Yes, when you read the story aloud and pause at the blank. The student can fill it in verbally, with a picture card, or with a gesture. Pair the blank with a picture cue so a non-reader has a way to respond.
Where in the story should a partial sentence go?
Place it at the end of a beat you want to reinforce, after the student has already read the full information at least once. A common pattern is to keep the first read fully complete, then reread with one or two sentences turned into blanks.
Is a partial sentence the same as a comprehension question?
They overlap but are not identical. A partial sentence keeps the student inside the story wording and cues recall. A comprehension question steps outside the story to ask "what did you do" or "why." Many school SLPs use a partial sentence during reading and a comprehension question after.
One approach for school SLPs short on time is to keep a 5-tool stack: a methodology checklist for the Gray sentence types, a slide template you reuse, a folder of stock photos sorted by scenario, an AI text drafter (ChatGPT, Claude, MagicSchool, or Emoquest for one-sentence-in story output), and a delivery format your district already uses. Wherever you draft, mark one or two lines as partial sentences before you print, so the comprehension check is built in.
