One lesson, one board

This is what a lesson with PhiBoard can look like in class - from recalling a formula, through a short quiz, to the notes that stay after class. You can run the same lesson remotely too.

Pick a topic from the formula card and a ready-made clipping lands on the board. There are three cards: primary school and secondary school - core and extended.

Ready-made lesson materials

You don't have to prepare everything from scratch. Everything below is free - for you and for your students.

Courses and lessons

Topics explained from the basics

Lessons that follow the national curriculum: explanations, drawings and examples solved step by step, and many lessons also have mini-games. New topics are added as we go.

Exercises with solutions

For class, quizzes and homework

Over 700 types of exercises from every section of the national curriculum - from grade 4 to the basic school-leaving exam. Each one comes with a step-by-step solution, and you can drop a set straight onto the board.

Nothing to install

It works in the browser on a computer, an interactive whiteboard and a tablet. There is also an app on the App Store and Google Play.

No student accounts

Students join a public board from a link as guests - they only give a name, no email and no password.

Built in Polish, from scratch

The interface, lessons and exercises are written in Polish with Polish schools in mind - not hastily translated from English.

Students' data is safe

The teacher decides who can see the board, and students don't have to give any personal data.

Private from the start

A new board is private until you change it - only the people you invite have access.

Guests without personal data

Students joining a public board only give a display name - no account and no email.

Full access control

At any moment you decide whether the board is public or available only to invited people.

Deletion on request

You can delete your account and boards at any time.

Your first lesson in three steps

No training, no roll-out, no IT department.

Create a free account

Signing up takes less than a minute - an email address or a Google account is enough.

Create a board

Give it a name. If students should join from a link without an account, untick “Private board”.

Start the lesson

Open the board on the interactive whiteboard in class, or send students the link and work remotely.
