What is reflection triangles?

Draw a triangle with a different reflection criterion at each point Learners place a mark inside the triangle showing their position relative to all three criteria A mark near one corner means strength in that area; a central mark means balanced across all three Discuss the positions and set targets based on the weakest dimension

How it works

A reflection triangle offers a more nuanced alternative to simple rating scales. Instead of rating understanding on a single dimension (1-5), learners position themselves within a triangle defined by three related criteria. Their position shows not just how well they are doing overall, but where their strengths and weaknesses lie relative to each other.

For example, a triangle might have "Understanding the concept," "Applying it to new problems," and "Explaining it to others" at its three points. A learner who understands the concept and can apply it but struggles to explain it would place their mark towards the understanding-application edge, away from the explanation corner.

This three-dimensional reflection is more honest and more useful than a single rating. It prevents the all-or-nothing thinking where learners say they either "get it" or "don't get it." Instead, they see that understanding has multiple facets and they can be strong in one while developing another.

Reflection triangles work for any set of three related criteria: knowledge-skills-application, fluency-accuracy-complexity, content-structure-style, or any three learning outcomes from a unit. They can be used at the end of a lesson, across a unit, or for longer-term goal-setting.

Classroom example

A Year 8 Mathematics and Numeracy class in a Blaenau Gwent school has been studying algebra. The reflection triangle has "Understanding equations" at the top, "Solving equations accurately" at the bottom left, and "Writing my own equations for problems" at the bottom right. Learners place their mark. Most cluster towards the "understanding" and "solving" edge, indicating they can follow procedures but struggle to set up equations from word problems. This gives the teacher clear direction for the next lesson.

Curriculum for Wales connection

Reflection triangles develop the "Reflect" strand of thinking skills by building nuanced self-assessment. They support progression within the Curriculum for Wales by helping learners understand that progress is multidimensional, not a single ladder, and can be applied across all AoLEs to develop metacognitive skills.

Rainbow Curriculum's Thinking Tools lens helps you plan where multi-dimensional reflection tools are used across your curriculum, supporting learners in understanding the complexity of their own progress.

Tips

Choose three criteria that are genuinely distinct. If two criteria overlap too much, the triangle loses its diagnostic power.
Model the process first with a non-academic example (e.g., rate your confidence in swimming, cycling, and running).
A common pitfall: learners placing their mark in the exact centre every time. Push for honest differentiation between the three dimensions.
Use the same triangle at the start and end of a unit so learners can see how their position has changed.
Combine with target-setting: the weakest dimension becomes the focus of the learner's next target.
