Angles and Protractor: Estimate, Compare, and Build
Estimate angles by eye, compare them, measure them with a protractor, and build target angles.
Function Graph Transformations
Study graph shifts, stretching and compression, reflections, and how coefficients change y = a·f(b(x - h)) + k.
All Simulations
Coordinates: Points, Symmetry, Transformations
Plot points, reflect shapes, and test transformations on the coordinate plane.
Crack the Enigma
A simplified Bletchley Park learning simulation showing how crib-based reasoning and logical constraints reduce Enigma settings step by step.
