360° Rotating Geometry Protractor

Diameter approx. 130 mm (5.11 inches). Constructed from robust, odourless plastic — tested for repeated bending and drop resistance typical of school bag environments. Full 360-degree scale with dual-direction numbering (clockwise and anticlockwise) for flexible interpretation. Smooth-turning swing arm locks gently in place when pressure is released — aiding deliberate angle setting. Lightweight and pocket-friendly design supports independent learning and peer-assisted activities. Used across UK primary schools, SEN resource centres, and adult education numeracy courses for accessible angle literacy development.
