Step-by-Step Guidance
1. Prepare the space with a large base surface placed where several children can reach without crowding.
2. Set out coloured bowls/trays around the base, leaving clear access routes for children carrying items.
3. Place natural materials into the bowls by colour family, keeping a small mixed “unsure” bowl for items that are hard to match.
4. Introduce the invitation: children can choose a colour area to contribute to and help create a shared rainbow shape on the base.
5. Model a simple colour match by selecting one item and placing it onto the base, keeping the demonstration brief.
6. Offer herbs as an option for green, allowing children to explore scent and texture before deciding where to place them.
7. Support children to add materials to their chosen colour band, noticing spacing and overlap without correcting the design.
8. If children compete for the same area, offer choices: share a band, split it into two sections, or swap roles (collector, sorter, placer).
9. Encourage children to compare shades when bowls run low, using the “unsure” bowl to prompt discussion and flexible thinking.
10. Pause to look together at the overall rainbow, inviting children to decide if they want to add more, change placement, or leave it as it is.
11. Document the finished collage and, if appropriate, leave it accessible for continued additions during the session.
Learning Objectives
Children may develop colour recognition and sorting through hands-on selection and grouping of natural materials (Mathematics). Children may explore texture, scent, and visual pattern as they combine items into a shared collage (Expressive Arts and Design). Children may practise sharing space, taking turns, and contributing ideas within a group task (Personal, Social and Emotional Development).
Adult Role
Stay emotionally attuned by noticing frustration around turn-taking or scarce colours and naming feelings calmly. Model simple, specific language such as colour names, shade words (light/dark), and action words (sort, match, place, curve) without over-directing. Scaffold when children are stuck by offering two clear choices or a small prompt, and step back when children are collaborating or deeply focused. Observe how children approach sorting, how they negotiate shared space, and which sensory materials they return to. Hold responsibility for safety by checking plants, removing hazards, and supervising any cutting or handling of twiggy materials.
Observation Cues
Looks for and selects items that match a chosen colour, including lighter and darker shades. Sorts items into bowls with increasing accuracy, or re-sorts after noticing a mismatch. Uses words or gestures to claim a colour area, offer materials, or request a turn. Adjusts placement to follow a curved rainbow shape, or chooses to create blocks, lines, or clusters. Explores herbs by rubbing, sniffing, or comparing scents, and returns to preferred textures. Persists with a colour section even when materials are scarce, by adapting choices or asking for alternatives.
