Academics
TradeForge
A day on the job with twelve trades, for ages 9–14. The electrician sizing a circuit, the plumber's slope, the baker's ratio, the nurse's dose, the driver's time — each worker is one piece of real math. You see a real job, guess the answer, then watch the worker compute it and explain. Applied arithmetic + a look at real careers. On-device, no accounts.

Meet the cast
TradeForge's twelve workers each do one piece of real job math: you guess the answer, then watch the worker compute it and explain.
Volt
(The electrician) - multiplies the volts by the amps to get the power
Pipes
(The plumber) - multiplies the length by the quarter-inch-per-foot slope
Rolla
(The baker) - divides the flour by 3 to keep the 3-to-1 ratio
Cara
(The nurse) - multiplies the milligrams per kilogram by the patient's weight
Cutter
(The carpenter) - multiplies length by width to get the floor area
Bristle
(The painter) - divides the wall area by 400 and rounds up to whole cans
Needle
(The tailor) - multiplies the yards per coat by the number of coats
Sprout
(The farmer) - multiplies the seeds per foot by the row length
Gear
(The mechanic) - divides the miles by the gallons to get miles per gallon
Fern
(The landscaper) - adds the sides twice for the fence around a garden
Penny
(The shopkeeper) - takes the percent off, then subtracts it from the price
Dash
(The delivery driver) - divides the distance by the speed to get the time
