Online tutoring in mathematics
No more camera pointed at a notebook and no more deciphering blurred handwriting. You draw, the student writes, and you both look at the same board.
The board stays after the session. The student returns to it while doing homework, and you can see what you covered last time without digging through notes.
Why it beats a camera
You see exactly the same thing
No guessing whether the student read a sign correctly. The writing is clean and identical on both sides.
The student solves in front of you
Hand over writing and watch every step. You see where the mistake happens, not just the final answer.
Notes stay with the student
The record of the session is available afterwards. Nothing has to be copied out or photographed.
Ready-made problem templates
Clone a board with a problem layout for the next student. Prepare the set once.
How a session looks
Book it and send the link
Hold the call wherever you normally do. Open the board beside it, in a second browser tab.
Explain by drawing
The graph, the figure or the worked formula appears in front of the student step by step, not as a finished picture.
Leave the student a record
Export the board to PDF afterwards, or leave it shared so the student can come back to it.
Frequently asked questions
Do I need a tablet with a stylus?
No, though a stylus helps with freehand sketches. A mouse is enough for shapes and formulas, and graphs are drawn from the formula itself.
Does the student need an account?
Working together on a shared board needs only the link. An account matters if the student wants to create boards of their own.
How many people can work on one board?
The board suits one-to-one sessions as well as a small group. There are no fees tied to the number of participants.
Can I use it for paid tutoring?
Yes. PhiBoard is free to use, including when you teach for a fee.
