Slime! Kids just can’t get enough of it. It’s squishy, stretchy, and undeniably fun! I know some parents and teachers have a love/hate relationship with slime, but let’s turn that into all love. After all, kids adore it, so why not use it to have some fun together and help them learn?

Alphabet slime pairs messy play with meaningful early literacy practice. All you need is a few simple ingredients and some plastic alphabet shapes to make your own ABC slime packed with letters to explore. You can use alphabet beads, small magnetic letter shapes, or any other letter forms that are small enough to mix into your DIY slime.

More than just messy fun, this activity is a positive way to spark creativity and build important early literacy skills. I’ve found that this kind of tactile, hands-on learning can be a remarkable tool to help kids learn their letters faster and retain them more easily. Plus, the time you spend making it and playing with it together creates such special bonds and memories, which will help fuel their learning and development over the years to come. 

Just follow the DIY alphabet slime recipe below with your child. Making it is part of the fun, so be sure to let them help mix it up. Once you and your little one have created your ABC slime together, use it for fun and learning! Your little one will love squishing, stretching, and exploring the slime while finding letters. 

You can use it to help your child practice letter recognition, letter sounds, or even spelling. As you play together, simply tell them the names of the letters they find, if they’re just starting to learn the ABCs. Then you can explain what sound that letter usually makes.

If they know some letter names or sounds, ask them to try to identify the name or sound of the letters they find. You can also call out a letter name and ask your child to search for it in the slime. If they’re ready, call out letter sounds—for example, /s/—and have them locate the letter that makes that sound. 

Once your child can read, you can even turn ABC slime into a tactile word search! Give your little reader a word to spell with their slime. This could be a spelling word they’re learning, a word they’ve struggled to read, or their own name for a budding reader. (Just be sure your slime has the necessary letters, for example if there’s a double letter in the word.) Then have them search for the letters to spell it. They can easily pull apart the slime to separate the letters to spell a word.

Adapt to your child’s level and the skills they’re learning, and be sure to keep it light and fun. (See How to Teach Your Child the Alphabet for more tips.)  

ABC slime is a fun and easy DIY learning tool that’s adaptable for children as they age and their literacy develops. Even better, it’s inexpensive—or free if you have supplies on hand and letter beads or magnets to upcycle!

DIY Alphabet Slime Recipe

Ingredients

  • 1/2 cup clear or white PVA school glue
  • 1/2 cup water
  • 1/2 teaspoon baking soda
  • 1 tablespoon saline solution that contains boric acid (check label)
  • Alphabet beads, foam letters, or ABC magnets
  • Optional: Food coloring or glitter

Instructions

Step 1: Combine 1/2 cup of glue with 1/2 cup of water in a mixing bowl. Stir well.

Step 2: Stir in 1/2 teaspoon of baking soda until fully dissolved.

Step 3: Add your letters and stir to mix evenly. Pay attention to the letters you include. For example, put in letters your child is learning and maybe all the letters of their name, including two of the same letter if needed. If you want to add food coloring or glitter, also add it now.

Step 4: Add 1 tablespoon of saline solution and mix. The slime will begin to form.

Step 5: Knead the slime with your hands until it gets stretchy and less sticky. Add a few more drops of saline solution if the slime is too sticky.

Store your slime in an airtight container, and you can pull it out anytime for a playful learning experience.
