Read a real harbor protractor to the exact degree — line up the baseline, pick the right scale, and log every angle.
A real protractor overlays each angle and the child reads it to the exact degree — lining up the baseline and choosing the inner or outer scale that reads zero on the base arm. Reading the scale (not eyeballing) is the skill. Best for Grades 5–6.
A free, no-signup, no-ads math game for Grades 5–6 — practising angle-measurement, read-protractor, inner-outer-scale, draw-angles, degrees. Play in your browser on the KidsDoMath games hub or explore more Geometry & Shapes games.
