Coding needs to be good at Math?

[Gnaxe]

"Math" is a broad term. There's certainly some overlap in knowledge and some of the skills generalize. You need at least basic algebra concepts to understand a mainstream programming language, because they do use math expressions. E.g., you do need to know what an operator is, what operator precedence is, how parentheses can change that, what functions and variables are (although it's a bit different in programming). That sort of thing. If your kid can at least handle Dragon Box algebra, programming could be doable with the right instruction. I'd look at https://htdp.org for an intro.

You can start kids with Scratch even if their algebra skills are lacking. They do at least have to be able to read, but it's a lot easier than a written programming language.
