Because this blog is dedicated to discussing mathematical ideas in the context of teaching them to k-12 audience I should rename it to “Mathematics for Teaching”. I do have some posts on other issues in mathematics education which frames some of the lessons discussed in the blog. Note that the domain name is now https://math4teaching.com. The old domain is http://keepingmathsimple.wordpress.com and still works, for now. Please update your links to this blog or better subscribe to my RSS or via email. Thank you.
