Painting a rainbow with a sponge could create the perfect rainbow, or it could turn into a page of brown paint! The important thing about a process art activity like this rainbow sponge painting is that the final painting isn't what this activity is about. It is about toddlers and preschoolers enjoying the process of exploring different supplies and the effects they can create.

Some toddlers and preschoolers will get stuck straight in and get covered in paint, others will be more cautious. Both of these reactions are ok!

As rainbow sponge painting uses lots of different coloured paint you will have lots of opportunities to work on colour recognition with younger toddlers and colour mixing with older kids. Learning whilst having fun is the best way of learning!

Below you can see the different directions my 2 year old and 5 year old took this sponge painting art activity. My 2 year old REALLY enjoyed watching my 5 year old create her rainbow too!

Whilst we have written directions below for this rainbow sponge painting art it is important to let your toddlers and preschoolers explore this process art in their own way. There is no right or wrong way to paint a rainbow. The directions below are just suggestions.


STEP 1: Prepare your supplies


Before inviting your toddler or preschooler to paint a rainbow get all your supplies to hand. You will need paints in all the colours of the rainbow as well as several sponges.  I like to use paper plates to pour paint onto, but this is optional.

What sponge should you use for rainbow sponge painting?

Don't worry too much about what type of sponge you should use to paint a rainbow, any sponge will work. Maybe experiment with a few different sponges to see which one gives the effect you are most pleased with.


STEP 2: Paint a rainbow


Now you have all your supplies it is time to invite your kids to paint a rainbow. Begin by demonstrating to them how you can add paint in all the colours of the rainbow to a sponge and swipe it across the page to make a rainbow. You will definitely get a few wows! Watching the rainbow appear as your swipe your sponge across the paper is almost magical!

Painting a rainbow activity for toddlers and preschoolers.

You can either add the rainbow coloured paint in lines to a paper plate and then dip a sponge into it (as shown) or you can squeeze lines of the different coloured paint across your sponge (as demonstrated by 'Hands on as we Grow'). I have found that with younger children dipping their sponge into the paint is easier, but experiment and see what works best for you.

Once the children have seen how you have painted a rainbow using the sponge let them explore different ways of creating their own sponge painting rainbow.

Easy rainbow painting activity for toddlers and preschoolers.

My five year old, 'Daisy', wanted to create a full rainbow in the same way as I had demonstrated. She later used a sponge paintbrush to add rain and clouds to her painting.

My 2 year old, 'Ollie', was so excited to get his hands on the rainbow sponge. He found it a little hard to create a full rainbow so he stamped the sponge on the paper instead of swiping it across.

After Daisy had seen Ollie's rainbow created by stamping the sponge down onto the paper after being dipped in rainbow paint she wanted to give it a go too!

As you can see, each rainbow sponge painting turns out differently. The way each child uses the sponge will be different, as will the way they mix the colours. Whilst you might end up with a perfect arch shaped rainbow with all the colours in the correct order, thats not what this paint a rainbow activity is about! It is about having fun exploring paint.
