Why Kwadrant Pro
Made for how maths really works.
Fractions, brackets and equations need more room than an ordinary sentence. That's why we designed Kwadrant Pro together with 12 secondary school maths teachers.
How to use it
From lesson to test.
In class: write out your workings neatly and put the subject and date at the top of the page.
When practising: write formulas on the inside of the cover, wipe them away and try again.
Before the test: use stickers to mark the pages with standard formulas and tricky problems.
- 360° lay-flat spiral binding, the notebook stays open flat
- 240 pages of squared paper
- Sturdy PP cover that can take a knock
Developed with teachers
Not a standard notebook, but one that thinks along with you.
Together with 12 secondary school maths teachers, we looked at what a maths notebook needs to do: room for calculations, an overview on every page and a cover that can take a knock.
Scholis is a Dutch brand, awarded the Dutch 'Website van het Jaar 2026' seal. Kwadrant Pro is available through scholis.nl.

What kind of squares does Kwadrant Pro have?
10×10 mm squares on 240 pages. That is roomier than a notebook with 5 mm squares, so fractions, brackets and equations have more space.
What level is this notebook for?
For maths in secondary school. Kwadrant Pro was developed with secondary school maths teachers.
How do I use the whiteboard inside?
Write formulas or intermediate steps on the inside of the cover with an erasable whiteboard marker and wipe them away again. Handy for quick practice or for keeping standard formulas close at hand.
Does the notebook lie flat?
Yes. The 360° lay-flat spiral binding keeps the notebook completely flat while you write.
What size is it and how many pages does it have?
The size is A4 and the notebook has 240 pages of squared paper.
What is the sticker sheet for?
You use it to mark important pages, tasks and deadlines, without losing loose sticky notes. The sticker sheet is bound into the notebook.
