A ready-to-run 10-minute activity that turns a real archival photograph into a source-criticism lesson: observe, reflect, question — with the game as the guided first step. Free, no accounts, nothing to install.
A photograph is the entry point to source-criticism because the questions are the same as for any document but the answers are visible: who made this, why, when, and what is it evidence of? The step most students skip first is the most important one — describing what is actually in the frame before interpreting it. This activity front-loads observation, which is exactly the skill a year-guessing game trains by forcing you to read a photo before you commit to a date.
The standard scaffold, in this order. First, observe — list only what is visible: clothing, vehicles, architecture, signage, film grain, any text in the frame. No guesses yet. Second, reflect — what does each clue suggest about a date, a place, a circumstance? Third, question — what is missing, who took the photo and for whom, what is framing or excluding? A wrong first date is not a failure; it is the moment the evidence gets interrogated.
Open guessNow and play one round together on a projector: as the photograph reveals piece by piece, students call out observations (step one) and the class tests a date at the moment you commit to a guess. Because the reveal shows the answer and then its full provenance record — photographer, licence and source — the debrief is where the criticism lands: you were wrong, here is the evidence that would have fixed it, and here is the real record that proves both. One round is roughly twenty seconds, so a full activity is five or six photographs and a worksheet in under ten minutes.
Give each student a sheet with three columns: WHAT I SEE / WHAT IT SUGGESTS / WHAT I WANT TO KNOW. Before the game reveals a round, they fill the first column; as the class discusses, the second; after the reveal, the third (often become: who is this person, what happened next). The sheet turns a shared screen into individual work product.
Every image in guessNow is a genuine archival photograph with its photographer, licence and source shown at the reveal — no stock, no AI-generated imagery. That is the whole point for this lesson: the source record is real and checkable, so the 'question' step has somewhere to go. The classroom guide explains the no-account setup, and the explainer on how our provenance record is kept shows students what a real attribution looks like. To practise reading the clues, the guide to dating an old photograph covers the technology, costume and signage tells, decade by decade from the Victorian era to the 1960s.
