The snowball technique is a structured, cumulative peer-learning activity that builds understanding and consensus step by step: individuals first generate ideas alone, then merge them in progressively larger teams, and finally bring the consolidated thinking to the whole class. Each stage “rolls up” prior contributions like a snowball, refining and expanding them through dialogue. It encourages collaboration, active listening, participation, valuing others’ ideas, and critical thinking, making it a powerful tool for exploring complex ideas.

• Connectedness

Age group	Student number	Duration
6-10 years old	Whole class (individual → pairs → groups of 4 → whole class)	30-45 minutes

Proposed step by step implementation of the learning activity

Step 1 – Teacher prepares a “prompt”: The teacher prepares a central, open-ended prompt related to any topic of any lesson. The classroom space (physical or virtual) is organized so students can work individually, then in progressively larger groups (pairs → small groups → whole class). Provide each student/group with a response sheet or digital slide to record and “roll up” ideas.

Instructions to give students: “Today we’re using the Snowball to explore how we can value both people and nature. First, you’ll think on your own and write down your idea(s). Then you’ll pair up, share and combine your ideas, and keep doing that—rolling them together like a snowball—until the whole class has one richer set of ideas. At each stage, listen for how your ideas connect people and the planet, and be ready to explain why what you suggest shows respect and care for both.”

Running the activity – step-by-step at each stage:

Step 2 – Individual idea generation (2–3 minutes): Each student responds privately to the prompt. Students can write or draw.

Step 3 – Pair merging (4–5 minutes): Students work in pairs. They share their individual ideas and merge them into one improved response. They record the merged idea on a pair sheet. The basic rule is to always listen and understand what the other person is saying and thinking. 

Step 4 – Small group consolidation (5–7 minutes): Two pairs join to form a group of 4 (or a suitable size). Each pair shares their merged response. The group discusses and creates one stronger consolidated idea.

Step 5 – Whole-class synthesis (8–12 minutes): Each group shares their consolidated idea. The teacher facilitates a collective map on the board The class identifies common themes, highlights balanced ideas, and selects 1–2 actions to try as a class.

Optional extension – Commitment/Action planning (3–5 minutes): Students choose one small action and write a pledge:

 “I will… because it helps people by… and helps nature by…”.
