### ⭐⭐⭐⭐⭐ super set of tiny protractors
*by M***3 on April 27, 2014*

These tiny 4" protractors are perfect for my kids and their math problems. Because they are smaller, the protractors fit the angles better and angle measurements are easier to read than larger protractors. With larger 6" protractors, kids have to draw extensions to the angles on the math page so that the angle sides reach the markings on the protractor. These tiny 4" protractors are much easier for kids to read. They also fit nicely in pencil cases, etc. I am glad there 12 though, because they are small and clear and hard to see/find if you misplace them. I had looked in lots of local stores (Target, Walmart, Staples, school supply stores) to find extra small protractors and couldn't. It was worth the price to order extra (12) even though I thought I only needed one or two. As a homeschool teacher, I am very pleased with the protractors and grateful for the good price.

### ⭐⭐⭐⭐⭐ The Best Class Set of Protractors
*by M***E on March 10, 2015*

I had a set of class protractors, but the class set was too big. The bigger sized protractor made it almost impossible to measure degrees of angles in books. This sized protractor is perfect! Fits nicely in a pencil bag and is easy to use in the book. Although this is a small protractor the numbers are clear and big enough to read with great accuracy. I have found also that these protractors are not breaking as easily, part of the reason I believe is that these protractors are not being pressed in books to get the measurement of an angle.

### ⭐⭐⭐⭐⭐ This is the superior protractor for young learners of geometry (I teach in ...
*by S***N on July 13, 2018*

This is the superior protractor for young learners of geometry (I teach in the middle school setting), and is much more suitable for working on small images of angles in worksheets and textbooks than the larger protractors. The dual rulers are essential for creations of polygons meeting dimensional specifications. I keep one of these in my home workspace for creating my own assessments and work projects.
