Brighten up a rainy day!

This activity is so quick to put together and kids will love moving and sliding the magnetic letters around the rainbow to sort them. All you need is a metal tray (a baking sheet works great), magnetic letters and a piece of paper with some markers.

📚Did you know? The word 'rainbow' originates from the Old English 'renboga' – 'regn' meaning 'rain' and 'boga' meaning 'bow.’

🤷No tray? No problem! If you don’t have a baking sheet, take this activity to another magnetic surface...your fridge!


For this activity you will need:

Magnetic letters

Blank piece of paper (preferably a neutral color)

Markers (red, orange, yellow, green, blue, indigo/purple)

Baking Tray

Learning Outcomes




Letter recognition


Identifying the letter that begins their names and its sound


Step 1:

On your blank piece of paper draw out 6 curves of each colour in a rainbow in the order from top to bottom: red, orange, yellow, green, blue, and indigo/purple. The curves should get a little bit smaller the farther you go down the page. 

Step 2:

Place your paper and the colorful magnetic letters on the baking tray.

Step 3:

Encourage your child to match the colors to the letters along the rainbow spectrum. If you have enough letters of each color, encourage them to spell their name or sight words using only one color.

⬆️ For older preschoolers:  Challenge older children with uppercase and lowercase letters. Get them to separate them, sort them and create words with the different letters!

⬇️ For younger toddlers: Matching the colors might be enough of a challenge for them.  Once they’ve mastered this skill, get the child to sort the letters — which color has the most/least amount of letters?
