  "summary": "Moving your hands is not the point; showing the relation is.",
  "kind": "heuristic",
  "body": "Use a simple, meaningful gesture that agrees with the explanation: grouping, direction, balance or separation. A child-mathematics experiment found that gesture content mattered. Treat use in adult explanations as an option to test, not a proven presentation upgrade.",
  "limits": [
    "Provide a verbal or visual alternative. Gestures may be unseen, culturally ambiguous or physically inaccessible."

      "claim": "Children assigned different gestures during a mathematics lesson learned differently; the information in the gesture mattered.",

      "note": "Does not demonstrate that arbitrary movement or adult presentation gestures improve learning.",

    "A spatial or relational explanation remains hard to follow."

  "example": "When explaining two groups that must balance, you indicate each group consistently instead of waving at an invisible collection of numbers.",
  "check": "Does the listener recover the intended relation without needing to copy your movement?",
