Timeline sort cards

Twelve documented moments printed as cut-out cards, spread deliberately across the ancient world, the medieval centuries, the industrial era and the modern age. Each card carries the event, the place and one visual clue — but no year. Groups order them, argue the sequence, then check against the answer key on page two, which prints separately so it stays with the teacher.

How to run it

  1. 1Print page one per group and cut along the dashed lines before the lesson — twelve cards per set.
  2. 2Groups order the cards oldest to newest, face up, and must justify each placement out loud.
  3. 3Only then hand out page two, the answer key with years, and have groups mark their own sequence.
  4. 4Extension: ask groups to name the century gap between the two cards they got most wrong.

Free to photocopy for your classes. Keep the footer credit and use it as often as you like.

Timeline sort cards

Order the cards oldest to newest. You must give a reason out loud for every card you place.

HistoryGuesser

Cut along the dashed lines. Twelve real moments, no dates. Order them oldest to newest — every placement needs a reason said out loud before the card goes down.

Marking and extension

  • Score the sequence, not the years: one point per card that sits between the correct neighbours.
  • Ask each group to name the two cards they swapped, then work out the century gap between them.
  • Follow-up: which cards could a student have ordered from the clue alone, and which needed prior knowledge? That distinction is the lesson.
  • Every event on these cards has a written account on historyguesser.app/moments if a group disputes a date.
