Those interested in shameless off topic self promotion that is related to math education, math, or somehow makes sense can post it here. However, don’t post links to discount drugs, etc. Those will be removed as spam.
Think of this as a nano Craig’s List for math ed or related areas.
You can post a link to any math book you have written, lesson plans in math you sell, etc. Or reviews of these. There is no endorsement from allowing these posts to remain.
