# Explicit one-attribute object sort
Skill: [data.probability.simple-chance-language](/math/skills/data/probability-simple-chance-language)
Family: Data Classification, Tables, and Graph Reasoning
Explicit one-attribute object sort grows by changing representation, numeric range, constraint count, distractors, language load, and transfer context.
## Variations
- 6. Advanced enrichment: Reason about the general method or a non-routine variant.
- 5. Challenge extension: Combine the skill with a second idea, hidden constraint, or explanation requirement.
- 3. Core task: Solve the target skill independently.
- 1. Foundation recognition: Notice the relevant quantity, shape, relation, or constraint before calculating.
- 2. Guided strategy: Use a visible scaffold, model, or narrowing move to choose a valid next step.
- 4. Transfer form: Apply the same idea when numbers, wording, or representation changes.
## Hints and Checks
- Decision restated without adding a new method.
- Common slip nudge: Treats a wanted outcome as more likely without counting or inspecting outcomes.
- One useful scaffold after help is requested.
