Goniometer (Angle Measurer)
For measuring and constructing angles from 0° to 180°. This replaces the common protractor for this curriculum.
WARNING: CHOKING HAZARD! Small parts. Not for children under 3 years.
Constantly comes apart
This seems like a simple product but the two halves are constantly separating. It’s not broken in the sense that it won’t work anymore, since they snap right back together, but it’s very annoying to use and has to be “babied” to get any functionality out of it without it coming apart.
This goniometer is junk
Numbers are very difficult to read and goniometer constantly falls apart when trying to use it. Very frustrating learning experience.
Not the best not the worst
It’s great that this is clear but the window for reading the angle is hard to tell exactly which degree you are at. Also ours gets to where is won’t stay together. When we first get it it snaps together tightly but with use throughout the year it loosens and starts to come apart on its own when we open and close it to find angles. Have had to replace it.
