Rainbow Themed Week
Our Weekly Virtual Book Club for Kids has some fun weekly themes and I must admit rainbow week is one of my favorites to do with preschoolers and toddlers. There’s something quite magical about a rainbow to kids and adults alike! Grab a prism (like this one on Amazon) and explore how you can make your very own rainbow with sunlight.
In the story How the Crayons Saved the Rainbow the Sun and the Clouds are best friends. Together they keep the world warm, the gardens growing, and the sky full of beautiful rainbows. However one day they get into a fight and refuse to be in the sky together. Which you can only guess means there are no longer any rainbows.
In the story, you discover that without rainbows, the colors start disappearing until Earth was left with no color … except for one little forgotten box of crayons in one little school desk. You’ll have to read with your preschooler to see how they solve this problem.
How the Crayons Saved the Rainbow teaches the importance of teamwork and perseverance through the eyes of some very colorful crayons.
After reading the story you’ll want to do some rainbow activities with your child and I’ve gathered some of my favorites just for you! Here’s a few more rainbow books to read too!

Preschool Learning with Rainbows
Rainbow activities provide a fun and hands-on way for preschoolers to learn several key concepts, including:
- Color Recognition: By exploring the colors of the rainbow, children improve their ability to identify and name different colors. This is an important skill in early childhood development.
- Fine Motor Skills: Many rainbow activities involve cutting, drawing, or arranging colorful objects, which helps develop fine motor skills as children practice hand-eye coordination and dexterity.
- Creativity and Imagination: Working with bright colors and a variety of materials encourages creativity. Preschoolers can experiment with different ways to create their own rainbow art and crafts, fostering imaginative thinking.
- Science Concepts: Rainbow activities provide opportunities to explore basic science concepts like light, rain, and the color spectrum. For example, children can learn how rainbows form through simple experiments or discussions about weather.
- Math Skills: Sorting, counting, and organizing rainbow-colored objects can help with early math skills like pattern recognition, sequencing, and understanding more or less.
- Language Development: As preschoolers talk about the colors, shapes, and patterns they see in their rainbow activities, they build their vocabulary and improve their communication skills.
- Sensory Development: Rainbow activities often involve sensory play with various textures, such as soft fabric, shiny paper, or smooth paint, providing opportunities for sensory exploration.
Overall, rainbow activities offer a rich learning experience that supports cognitive, physical, and emotional development in preschoolers.
