Behind the Design

The most common mistake kids make with a protractor is reading the wrong scale. A standard protractor has two rows of numbers running in opposite directions, and without a visual cue, it's easy to pick the inner scale when you need the outer one, or vice versa.

Sonic's SN-886 addresses this directly by printing the left-side numbers and the right-side numbers in different colors, with matching colored lines marking the center baseline. The color ties the scale to its corresponding side of the ruler, giving students a visual cross-check before they write anything down. The name sticker on the back is a small but considered detail for a classroom context where identical tools get mixed up constantly.

A 12cm semicircle protractor built for kids who are still learning which scale to read. The left and right degree scales are color-coded, and matching colored reference lines mark the center point, so lining it up correctly is obvious at a glance.
