Rational Exponents and Real Numbers
Grade 9 · Extend exponents to rational values; properties of rational and irrational numbers
Tools that work like the real thing: simulators, data and models that students run and question. 209 tools across 12 subjects.
Spin a 3D atom, light up its emission spectrum and wander the whole periodic table. No quiz, just curiosity.
Set the ticket price and watch the line, the empty seats and the resellers. Then take the show on tour and find each city's price from the sales.
A full step-sequencer studio in one file: 214 sounds and 10 drum kits, 30 instruments, your own samples, a piano roll, a song playlist and a mixer with sidechain pump and a DJ filter. Export your track as a WAV.
All 26 handshapes of the ASL manual alphabet, any word or name fingerspelled at the speed you pick, and a reading game that speeds up every time you get one right.
Set up twenty pictures the way ASL does: decide what stays still, choose a classifier handshape for each object, then place and move them in signing space and flip to the viewer's view.
Pick a real city, a real starting job and a place to live, then survive twelve months on your own: paychecks under 2026 tax rules, surprise bills, roommates, a credit card and a year-end report card. Class codes give everyone the same year.
Travel to any year from 1928 and ride real returns forward with your mix of stocks, bonds, cash and gold. See what time, inflation, fees and a bad start year really do. Educational only, not advice.
Nothing here is built yet. Everything on this page is still on the bench.
