Welcome to the world of NB Teacher!
📚 Books and notebooks that grow with your child 💡
From the very first look to the very last math problem.








About me
📌 My name is Natalia Branicka.
I'm a high school math teacher — and also a mom to a curious 4-year-old explorer.
I’ve always been fascinated by how the brain works — especially the youngest one: still developing, but incredibly absorbent.
I knew that if I wanted to support my child’s development, I had to act early — wisely and mindfully.
🧠 Neurobiological research is clear:
At birth, a child's brain reaches 25% of adult brain weight.
By the end of the first year — 75%.
By age 6 — up to 95%!
This is when the brain is at its most plastic and receptive — and the right stimulation can help prevent future learning difficulties, such as dyslexia.
🔍 While searching for books for my son, I wanted something:
– simple and well thought out,
– supporting visual and language development,
– truly adapted to his stage of growth.
❌ I couldn’t find it.
✅ So I created it myself.
Today I create books that grow with your child — from high-contrast baby books, through educational coloring pages and stories with Leo the Lion, to notebooks and tools that support older learners.
🎯 My areas of focus include:
– cognitive development in children aged 0–6,
– modern learning strategies,
– education rooted in neurobiology.
📚 You’ll find in my offer:
📖 high-contrast and sensory books,
🎨 educational coloring books and therapeutic stories with Leo,
✏️ notebooks for modern note-taking methods,
📂 guides, PDFs and practical tools for smart learning.
🌱 My goal?
To create resources that help children grow to their full potential —
and support parents and teachers with wisdom and heart at every stage of learning.
