Teachers can tailor the Snowball Technique to three difficulty levels to develop Connectedness and Valuing People and Nature. 

• Beginner learner (6-7 years old): At Level 1 (Foundational), use very concrete, familiar examples (e.g., sharing school garden produce or reducing snack waste) and keep the progression simple (individual → pair → whole class); provide strong scaffolds like teacher modelling, sentence stems, and visuals linking people and nature, and assign clear roles so every child can contribute safely. 
• Advanced learners (8-9 years old): At this level 2, introduce relatable but broader scenarios (e.g., cleaning the playground while protecting wildlife), run the full snowball (individual → pair → small group → whole class), require pairs to name the “bridge” between human and environmental benefits, use two-column merge sheets and guiding questions, and prompt groups to tweak ideas to be more inclusive.
• Expert  learners (9–10 years old): At the expert learners level, surface mild trade-offs (e.g., building a path versus preserving plants), expect students to compare or defend integrated ideas, include concrete mini-actions and structured peer feedback, and give learners more autonomy in selecting, refining, and balancing solutions while reflecting on how they honoured both people’s needs and nature’.
