What are 3-2-1 and GIST summaries?
These are short ways to sum up a reading or lesson. In a 3-2-1, kids write 3 facts they learned, 2 new words or interesting ideas, and 1 question they still have. A GIST is a one-sentence summary of 20 words or fewer, which forces them to pick only the most important ideas.
- 3-2-1: facts, words, and a question.
- GIST: one sentence, 20 words or fewer.
- Both often appear as an exit ticket at the end of class.
Why schools teach it
Summing up is how learning sticks
Students determine the main idea of a text and summarize it (RI.4.2, RI.6.2). Asking kids to pull out the most important points right after reading helps them remember, and shows the teacher what they understood.
The 20-word limit in a GIST is the point: it makes kids choose what matters most instead of retelling everything. Our writing guide to summaries covers longer summaries.

What to say, and what to skip
Say this
What are three things you learned?
3Which two words were new?
2What do you still wonder about?
1Can you say it in one sentence, 20 words or fewer?
GIST
Skip this
- Copying the first sentences of the text.A summary covers the whole section.
- Letting the question be “none.”There's always something to wonder.
- Counting words strictly at first.Getting close to 20 is fine while learning.
