Diamond Ranking

Diamond ranking is a discussion tool where learners arrange nine statements or ideas into a diamond shape based on their relative importance. The shape forces a clear hierarchy: one item at the top (most important), two on the next row, three in the middle, two below, and one at the bottom (least important).

Give each group nine statement cards related to your topic. Groups discuss and negotiate where each card sits in the diamond. The rule is simple: they must reach consensus and be ready to justify every placement.

The diamond shape is what makes this different from a simple rank order. The middle three are explicitly "equally important", which removes the pressure of ranking everything precisely. This frees up discussion for the extremes, where the real thinking happens.

Use this flexibly. If learners generate extra ideas, redesign the diamond to fit rather than forcing exactly nine. A 1-2-3-4-3-2-1 pattern works for 16 items.

Diamond ranking develops the "Develop" strand of thinking skills, specifically forming opinions and making decisions. It works naturally across all six AoLEs because any topic with competing factors, causes, or viewpoints can be ranked. It also builds the cross-curricular literacy skill of constructing reasoned arguments.

Rainbow Curriculum's Thinking Tools lens lets you track where diamond ranking appears across your curriculum, so you can build progression from simple prioritisation tasks in Year 3 to nuanced multi-factor analysis by Year 9.
