I start things for students in Cambodia: national math olympiads, a student leadership council, a debate club, and a charity tour that delivers school supplies across the provinces.

(About)
I'm Rita. In 2023 I founded the Youth Mathematics Organization so that any student in Cambodia could compete in mathematics, whatever their family could afford. Since then I've run national contests, led councils and clubs, tutored olympiad students, and made the videos and posters that bring people in.

Organization
YMO is a non-profit run by young people, for young people. Our competitions cost students as little as $1 to enter, and our charity tour gives back to schools, hospitals and children's centers across Cambodia.

STEM in
Khmer
I make Khmer-language STEM videos on TikTok and Facebook, film recap videos for YMO's contests, and vlog from events like YYGS and SIMOC. I've livestreamed 6 events, including YMO award ceremonies, to 2,000+ viewers.

Design
Running YMO meant someone had to make the posters, so I learned to design. These are pieces I've made for our competitions, partners and events: posters, placards, T-shirts, medals and trophies.

Awards
The physical side of every event: medals students take home, trophies on stage, and what the team wears and carries on the day.

The award medal for the YMO Tournament. I designed both faces and modelled them in Blender. Drag the medal to turn it, or scroll and watch it flip.
