Sequencing

An ordering activity where learners arrange a set of statements, events, images, or steps into a logical or chronological sequence, developing understanding of process, cause and effect, and narrative structure.

What is sequencing?

  • Provide a set of cards, each describing a step, event, or idea
  • Learners arrange the cards in the correct order (chronological, procedural, or logical)
  • Discuss and justify the chosen sequence, especially where order is debatable
  • Compare different groups' sequences to explore alternative orderings

How it works

Sequencing requires learners to understand relationships between pieces of information. Placing events in chronological order requires understanding of when things happened and how they relate. Placing steps in procedural order requires understanding of dependency: what must happen before something else can occur. Placing ideas in logical order requires understanding of argument structure and reasoning.

The activity works best when the sequence is not immediately obvious. If learners can sequence the cards without thinking, the activity has no value. The cards should include items whose position is debatable, items that could go in more than one place, and items that require discussion to resolve.

Give learners the cards physically so they can manipulate them. The ability to pick up a card, move it, try it in different positions, and discuss with a partner is central to the learning. Digital sorting loses this tactile, collaborative quality.

After groups have created their sequences, comparison is essential. If two groups have placed the same card in different positions, both must justify their choice. This comparison often reveals that there are multiple valid sequences, which is a more sophisticated understanding than simply "getting the right order."

Sequencing works across subjects: historical events, scientific processes, mathematical procedures, narrative plots, musical compositions, and physical education skill progressions.

Classroom example

A Year 6 Science and Technology class in a Ceredigion school is studying the digestive system. Learners receive twelve cards describing stages of digestion, from food entering the mouth to waste leaving the body. Most groups correctly sequence the early stages but disagree about the order of absorption and water reabsorption. The discussion about whether the large intestine comes before or after most absorption has occurred deepens understanding of the system far more effectively than a labelling exercise.

Curriculum for Wales connection

Sequencing develops the "Develop" strand of thinking skills through ordering, reasoning, and understanding cause and effect. It builds cross-curricular literacy and numeracy through logical structure and procedural understanding, and works across all AoLEs wherever process and order matter.

Rainbow Curriculum's Thinking Tools lens helps you plan where sequencing activities are used across your curriculum, ensuring learners develop logical thinking that transfers across subjects.

Tips

  • Include one or two cards whose position is genuinely debatable to generate discussion.
  • Use physical cards, not worksheets. Moveable cards allow experimentation and revision.
  • A common pitfall: providing too few cards so the sequence is obvious, or too many so it becomes overwhelming. Eight to twelve cards is usually ideal.
  • After the activity, ask learners to identify the most critical step: "If you removed one card, which would break the whole sequence?"
  • Combine with living graphs to add a second dimension (e.g., sequence events chronologically, then evaluate their impact).
