       @tomjennings at first I thought you had one of those decimal feet rulers, which look like they were designed by a very drunk guy to this metric-only person

       @tomjennings "An educational apparatus used for the teaching of mathematical operations that use fractions." https://www.freepatentsonline.com/6192594.html go figure 🙂

       @tomjennings If it’s a school ruler, my guess would be to help students visualize comparisons between fractional amounts.  For example, kids often have trouble internalizing that sevenths are smaller than sixths.

       @tomjennings I am sure there's ancient Egyptian scrolls with some kind of "new, better way of teaching math".

       @Catawu A retired school math teacher owns it. They're teaching aids for fractions somehow.

       @tomjennings I’m thinking it would work for my pastry doughs!  1/3 thicker than…  etc. Rolling dough —- over course those marks get pretty deep on that ruler…I’d have dough that is elbow deep!  I think it’s a good teaching aid. I thought about it yesterday… a good visual. I’m  a visual learner.
