Materials

• Colored paper or cardstock in red, orange, yellow, green, blue, indigo, violet (or any seven-color set)
• White cardstock or a sturdy backing sheet
• Scissors
• Glue stick or craft glue
• Pencil and ruler
• Cotton balls or white paper for clouds (optional)
• Markers, stickers, or sequins for decoration (optional)

Why kids love it

• The 3D effect looks magical when the rainbow arches off the page.
• It’s tactile: folding, curling, and gluing keep little hands busy.
• The craft can be personalized with names, patterns, or additional elements like suns and rain.

Step-by-step: Simple 3D Rainbow

1. Prepare stripes: Cut seven strips of colored paper about 1–1.5 cm wide and 15–20 cm long. Cardstock gives a sturdier arch; thinner paper curls more easily.
2. Curl the strips: Gently roll each strip along a pencil to create a soft curve. For a more pronounced 3D effect, fold each strip into a gentle arc rather than curling tightly.
3. Mark placement: On the white backing, draw a shallow arc as a guide where the rainbow will sit. This can be a pencil semicircle or a faint template.
4. Attach ends only: Glue the ends of each colored strip to the backing so the center of the strip lifts away from the paper. Start with the red strip at the top of the arc and layer the remaining colors beneath it, keeping consistent spacing.
5. Build the rainbow: Continue gluing ends for all strips, ensuring they align into a tidy arc. Press the glued ends firmly and let dry.
6. Add clouds and details: Glue cotton balls or white paper “clouds” at each end to hide the strip ends. Decorate the background with sun, raindrops, or stickers.

Variations to try

• Mini rainbows: Use shorter strips to create small rainbows for cards or bookmarks.
• Layered texture: Use different materials for each color — tissue, felt, foil, or patterned paper — for sensory variety.
• Pop-up card version: Attach the outermost strip to the inside of a folded card so the rainbow pops up when opened.
• Story prompt: Turn the finished rainbow into a page in a handmade book and ask kids to write a short tale about where the rainbow leads. If you want to add a moment of silliness, you might include the best joke about anger for kids to make them laugh before they write.

Teaching moments and skills

• Color order and sequencing: Talk about ROYGBIV or have children arrange strips by memory.
• Fine motor practice: Cutting, curling, and gluing strengthen hand skills needed for writing.
• Following instructions and creativity: Children practice a sequence of steps while making choices about decoration and materials.

Classroom or group adaptations

• Assembly line: Assign cutting, curling, and gluing to different children to build teamwork.
• Collaborative mural: Combine multiple rainbows into a large sky on bulletin-board paper.
• Cross-curricular tie-ins: Link the craft to weather lessons, poetry about rainbows, or color-mixing science demonstrations.

Safety and cleanup

• Use child-safe scissors and supervise glue use with younger children.
• Limit glitter and small embellishments for toddlers to avoid choking hazards.
• Keep a damp cloth or baby wipes handy for easy cleanup of glue and marker marks.
