r/matheducation rules, stats, and what to post

This community is for discussions of math teaching and pedagogy. The people here are math teachers. They talk about how to teach math, not about how to do math. The rules make the split clear. If your post is aimed at students of mathematics, it does not belong. If it is aimed at teachers of mathematics, it fits. So the room is for people who teach, and the conversations are about teaching methods, communication of ideas, and pedagogy.

Three rules decide everything here. “Homework or Math Help” says the community is focused on mathematics pedagogy, the teaching of, so avoid homework posts and any how do I solve this type question. “Self Promotion” allows you to share mathematical content you created if it is thoughtful, focused, and related to teaching mathematics, but only on Saturdays PST, and posts on any other day get removed. “Not related to math teaching” is the filter that trips up most marketers: a post about a specific mathematical concept is not enough, but a post about different ways to communicate common ideas can fit. The rule states the key plainly: if your resource is aimed only at students of mathematics, it is not appropriate, and if it is aimed at teachers of mathematics, then it fits.

A good post here speaks to the teacher, not the student. The rule text gives you the test: a post about different ways to communicate common ideas fits. So share something thoughtful and focused that helps a teacher teach better. If you built something yourself, the “Self Promotion” rule gives you one clear window, Saturday PST, so save your post for that day and make sure it is genuinely about the teaching of mathematics. A tool that helps teachers explain a tricky concept, a discussion of classroom approaches, or a resource built for educators all have a path here. Read your draft once and ask the question the rules ask: is this aimed at teachers, or at students? Only post if the honest answer is teachers.

Three things get posts removed. First, homework help. Any post that asks how to solve a specific problem, or helps students with their math work, does not fit because the community is about pedagogy. Second, self promotion on the wrong day. If you share content you created on any day other than Saturday PST, it gets removed. Third, student-facing material. If your resource is aimed at students rather than teachers, it breaks the “Not related to math teaching” rule, even if the topic is mathematical.

I like that this community answers its own hardest question right in the rules: if your resource is aimed only at students, it does not belong, but if it is aimed at teachers, it fits. That single test makes this one of the clearer rooms to prepare for. The Saturday PST rule is strict, so plan your week around it instead of hoping a Tuesday post slips through.
