Phyō is a library of state-of-the-art interactive tools for math and science. You grab something on screen, move it, and watch what happens. Seeing a shape rotate in real time teaches symmetry faster than a picture in a book.
Every tool is interactive. These are the three kinds you will find.
A guided walkthrough of one idea. You change the inputs and the picture responds. Start here if the topic is new.
A scenario, a problem, and a set of tools to choose from. Some tools fit, some do not, and choosing is part of the work.
Open-ended tools you drive yourself: a number line, a coordinate plane, a balance scale, and more. Model a problem your own way.
A few to try first. Pick one and start moving things around.
quality > quantity
Each tool is built to teach one idea well. A few things that work beat a lot that do not. Nothing here is generated or auto-filled.
Move the sliders, drag the shapes, and watch the result. Abstract ideas turn into something you can see and change.
Put one on the board and let students explore it. Each tool is self-contained and needs no setup.
You want to understand how something works and would rather poke at it than read about it. No prerequisites required.
learn together, in real time
Go live and work on the same thing at the same time. Controls, drawings, and presence sync instantly. No accounts required.
Controls and drawings sync instantly between everyone in the session. Up to 10 users can join and explore together.
No accounts or setup. Open the URL and you're in. Late joiners automatically sync to the current state.
Edit mode lets everyone interact. View mode broadcasts a read-only demo. Live presence shows who's connected.
Live sessions are entirely optional. Phyō runs offline as a progressive web app. Live sessions are the only feature that needs a connection.
for parents and teachers
The tools do the teaching. These two additions help the grown-ups keep up, whether you are helping at the kitchen table or assigning work to a class.
A plain-language walkthrough of the concept behind a tool, written for a grown-up who may not be comfortable with the math. Read it on screen or print it out.
Ready-made worksheets. Answer them on screen and check your work instantly, or print a blank version with answer spaces for the classroom.
from geometry to the environment
Phyō is early, and the roadmap reaches beyond math. These are a few of the simulations currently being designed.
A 2D cellular-automata simulation. Turn up the heat, add clouds and pollutants, and watch the water cycle respond.
Watch how pollutants move and disperse through a waterway over time.
A few days before the project began, I was helping my sister with geometry homework. She was stuck on rotational symmetry, and the static pictures in her textbook were not helping.
When she saw the shape rotate in real time, with a ghost of the original underneath it, she understood it.
