Twelve lessons taking a first year from a steel rule to reading a micrometer and interpreting a tolerance on a drawing. Built for a class of 28 with limited instruments, so measurement runs as a rotating station while the rest of the class cuts and files. Includes lesson plans, printable drawings, a station rotation chart, a competency checklist mapped to the Polish mechanical qualification, and a one period end assessment with a marking key. Polish and English, delivered as editable documents plus PDFs. Taught in five schools since 2022 and revised twice on teacher feedback.
