One landscape classroom reference connects the circle ratio, circumference/area formulae, exact symbolic answers and a checked radius example. Includes exactly 100 truncated decimal digits after the leading 3, a counterexample to an infinity misconception, the distinction between h and reduced Planck constant h-bar, a dated Google 2022 milestone and a carefully scoped NASA/JPL precision example. The historical milestone is not presented as the current record.
What’s included: six matching single-page vector PDFs: A3/A4/US Letter, colour and black-and-white, with matching logos. Native editable text/shape SVG, editable teaching text and source/use guidance bring the ZIP to nine files. These are six print editions of one poster. Core ideas approximately ages 11–16, with optional teacher-selected logic/physics/precision extensions. Small-print extensions are for close reading; classroom viewing distance affects legibility. This chart reveals several companion quiz answers, so cover it during unaided recall.
