Every equation is a machine — dial x until the output hits the goal, or undo the machine with the inverse operation.
Every equation is a little machine that takes x, applies one operation, and shows an output, and the child dials x until the output hits the goal — discovering that the inverse operation is the shortcut. Four kinds appear: x plus b, x minus b, b times x, and x divided by b. It builds one-step equations, inverse operations, and solving for x, as a single computed step rather than a two-step balance. Best for Grades 4–6.
