Make a Lego Rainbow

We are huge Lego fanatics.  We have made our own Lego Instruction Books; we’ve done Lego playdoh printing, car races, relay races, hunts, and Lego painting! My son just celebrated his fourth birthday and I threw him a Lego-themed birthday party that was a big hit.

Lego Rainbow-1-2

Our house is now even more inundated with Legos than it was before… so we’ve been using our imaginations to create loads of activities using our new toys.

Lego Rainbow

Since we love anything holiday-related and are getting excited for St. Patrick’s Day, we decided to create Lego rainbows this week.

These rainbows can easily be made without any tools other than Legos and a white piece of paper, but I decided to make a little paint rainbow to help my son have a visual organizer as he created his rainbow.

Materials Needed for Lego Rainbow:

  • an assortment of Legos in various sizes
  • chunky markers (we used our do-a-dot paint markers)
  • large drawing paper

Directions to Make Lego Rainbows:
  • (Optional) Draw a rainbow on the large drawing paper to use as a visual organizer for your child. You can also let your child do this.
  • Sort your Legos by color
  • Start creating your Lego rainbow!


We love to embed learning into our simple activities. This project focused on learning about…
  • the colors of the rainbow (pairing the visual color with the name of the color)
  • sizes and shapes (we talked about the different sizes/shaped Legos while we created)
  • directions (right, left, on top, around, etc. were all vocabulary words reviewed during this activity)
  • patterns (My son attempted to organize some of the rows of Legos in different patterns- ABBA, ABA, etc. We talked about them while we created)
If you’re looking for any other beautiful rainbow themed posts, there were several shared over on It’s Playtime. I also loved Heather’s Primary Colors Wheel and Jamie at Hands On: As We Grow had fun finding a rainbow with her son in their toys. Wouldn’t it be fun to use Legos and paint to teach kids about mixing primary colors to make the colors of the rainbow?
Do you have any other simple rainbow projects that you like to do with your kids?
What about any other Lego themed activities?
