Thinking Routines / Think, Puzzle, Explore
Open a topic by finding out what a class thinks it already knows — including the bits that are wrong — then turn the gaps into questions worth chasing.

Think, Puzzle, Explore is a thinking routine for opening a topic. Children say what they think they already know, what puzzles them about it, and how they might find out more. It surfaces prior knowledge and misconceptions before any teaching happens.
Give the topic as a single word or picture and take everything, without correcting anything. Then ask what puzzles them. Finish by turning two or three puzzles into things the class could actually go and find out. Fifteen minutes, at the start of a unit.
No. Write them up as they are said. Correcting on the spot teaches the class that the first column is a test, and the honest answers dry up. Come back to the board at the end of the topic and let them cross out their own mistakes instead.
Leave the board photographed and come back to it in six weeks. The lesson where a class reads its own opening answers after finishing a topic is worth more than the routine itself — there is always a howl of laughter at something they were certain about, and then somebody notices the puzzles they never actually answered. In my experience that is where the best independent research questions come from, not from the original lesson.
Any topic children arrive with half-formed ideas about.
Correcting the first column. The moment a wrong answer gets fixed on the spot, the class learns that Think is a test, and the honest answers stop. Write everything up as it is said, and come back to correct it at the end of the topic instead.
Think, Puzzle, Explore suits Year 2 upwards, grade 1 in the US. Younger children need the topic narrowed to something concrete — 'volcanoes' rather than 'the Earth'. Older classes can take the Explore step seriously and plan real research from it.
Photograph it and keep it. Coming back at the end of a topic and reading the opening answers aloud is the most convincing evidence of progress a class will ever get — and the puzzles nobody answered make an obvious list of independent research questions.
Once per topic, at the start. It is designed to be run before teaching, so its natural rhythm is one per unit — and pairing it with Connect, Extend, Challenge at the end gives you a before and after on the same piece of paper.
| Year group | US grade | What to change | How long |
|---|---|---|---|
| Years 2–3 | Grades 1–2 | One concrete topic. Accept everything, correct nothing. | 10 min |
| Years 4–5 | Grades 3–4 | Push for real puzzles, not just questions with easy answers. | 15 min |
| Year 6 and up | Grade 5+ | Turn the Explore column into assigned research. | 20 min |
Think, Puzzle, Explore opens a topic; Connect, Extend, Challenge closes it. Used as a pair on the same unit they show a class how far it moved, which is more convincing to children than being told they have learned something.
