4-in-1 Ruler

The four and one ruler is one of the best rulers around, often overlooked. It's unbeatable for drawing lines with pencil or pen or even marker as the edge is slightly raised so there's no Meyer as you move the ruler along. Also, it's one of the only rulers that's marked out in tenths of an inch on one of the scales. Nice to be able to teach that.

I bought this for my kids because we need a ruler that is in broken into tenth inches instead of sixteenths and this works great! It’s sturdy and easy to read. Shipping was also fast and reasonably priced. Highly recommend!

This ruler is amazing for teaching tenths. Most rulers do not have the four scales that this one does - 1/16 inch, 1/10 inch, 1/2 cm and 1/10 cm. Great tool!

I ordered two extra, since my kids were always wanting the single one we had and ignoring the plethora of wooden rulers that stay on the shelf. Now my 15-year-old can keep one with his stuff, someone else can have one, and I'll still have one left for math lessons!

Best I've come across

I ordered a second one of these rulers because they are great. The material is good quality and yet the edge is not too thick. I especially like that one side of inches is divided into tenths. You just can't find that much at all. It's been a very useful ruler for our family.
