I don’t recall ever learning number lines in school. Was in eighties. Are number lines a new teaching tool or am I just not remembering this?

- achileas 4y agoYou might be forgetting them, it's literally just a line with numbers marked on it. I learned them in primary school in the 90s, further classes never used them but they've always been useful tools for visualizing relationships between numbers.
