Tidying up i found a sample from the Olivetti Dora (probably an eBay listing). I see that it has thirds as nut fractions. The Brother typewriter i have doesn't have thirds, but has 1/8, 3/8, 5/8, 7/8 instead.
This Pica on the Dora has a closed figure 4, on the Olivetti sample i used in my blog post on Pica https://home.octetfont.com/blog/pica.html the figure 4 is open. The ancillary glyphs show less consistency.
What fractions does your typewriter have? (please boost)
Build your own fraction, see it come to life! With the "Fractions: Intro" sim, students can explore fractions through diverse representations like cakes and cylinders, all while comparing values to the numerator and denominator. https://phet.colorado.edu/en/simulations/fractions-intro #math #fractions
Want to know something crazy? I don’t know how to teach someone #fractions - specifically 1/3 etc.
I did really bad in school for a variety of reasons. I was great at math whenever I understood the teacher. Otherwise I didn’t learn anything at all. For example fractions. I’ll admit this is something I was fairly ashamed of. Not so much anymore now that I realize everyone is mostly just making it all up anyway.
Kids enjoying fractions?
Assistance request + Mah brain math is broken.
If I have a pdf that printed at 100% gives an output of 1/3 size - how much do I have to reduce the percentage to print the same thing at 1/4 size?
Thankyou in advance.
[No jokes ta, this is a real math question that is causing me headaches .. ]
