Behind the Design

Reading a standard protractor trips up a lot of students because the inner and outer degree scales share the same ring of numbers, and it's easy to grab the wrong row. Sonic's Fun Learning Protractor addresses this with color-coded numbers that visually separate the two scales at a glance.

A colored reference line marks the center point of the baseline, removing the common alignment mistake of placing the wrong spot over a vertex. The result is a protractor that teaches correct technique through its own visual cues rather than requiring repeated correction from a teacher. PMMA keeps the material clear and scratch-resistant enough for classroom use.

A 9cm protractor with color-coded degree markings and a colored center reference line to help students read angles and align the tool without guessing. A name sticker is included so it stays with its owner.
