Rain, rain, go away. Come again another day. It seems like my kids have been singing this sweet little tune every day for months now! The rain started in our part of the world and it just hasn’t let up. Instead of dwelling on the dreary, we decided to look forward to the new growth and the beautiful rainbows that will result from the weeks of downpour. In March, we will focus our homeschool to a rainbow unit study to help the kids understand rainbow color sequencing, primary colors, color mixing, and how rainbows form!

Acrylic Prisms– You can use glass prisms as well and they may actually work a little better , but I like to use acrylic prisms to avoid the risk of them shattering in the hands of toddlers and preschoolers.

Rainbow Magnets– My kiddos would not put these rainbow magnets down during our rainbow unit study…as you can see, the red one is missing in this photo because my daughter wouldn’t give it back to mommy 🙂 I cut up some primary color pipe cleaners and placed them in the jelly jar beside the magnets. The kids can use the magnets to move the pipe cleaners up and down the jar.
