Hate to say it...but we had inkwells and steel pens.
As I remember it, addition was 1st grade, subtraction in 2nd, multiplication in 3rd, division in 4th, fractions in 5th, and decimals in 6th. We were introduced to concepts earlier, but we were expected to have mastered them by the end of each year.
Today kids are introduced to fractions in 1st or 2nd grade, in fact that’s the problem. They are introduced to all kinds of things, but they aren’t allowed to master anything. My knowing times tables seems like magic to them. I’ve seen 8th graders, not special ed students, struggle with their fours tables. They mash buttons on their calculators and if they press the wrong button they are clueless as to why they got the wrong answer.
