Learning Letters That Make a Big Splash
Letters from Pebble are so much more than a collection of facts or lessons – they're story based designed to build connection.
Pebble the Harbor Seal lives in Cape Cod, but brings kids on exciting adventures where they learn about new places, animals, cultures and more. He wonders out loud, asks questions, and invites kids to share what they think – making reading and writing feel playful and engaging.
Here's what makes these learning letters so special:
- Screen-free fun your child genuinely looks forward to
- Story-first, focused on connection and curiosity
- Interactive and creative, with prompts that invite kids to respond, draw, and share their ideas
- Highly shareable, giving kids something they’re excited to talk about at dinner, school, or bedtime
No apps, logins, or screens required. It’s reading, writing, and imagination – wrapped into a weekly ritual your family (or classroom!) will cherish.

Letters Backed by Literacy + Designed with Intention
For preschool through early elementary.
Pebble’s letters are created by real educators and literacy specialists who understand how children develop reading and writing skills at different ages.
Each letter is intentionally structured to support key literacy skills, like comprehension, vocabulary, and early writing – while still feeling like a story your child wants to read.
The result is an experience that’s playful on the surface, and grounded in sound educational practice underneath. Meet children exactly where they are and watch them learn and grow week by week!
