After going back and forth for a few months about whether or not I should join the National Council of Teachers of Mathematics (NCTM), I finally decided to do it. I happened to send a tweet a few days ago asking for opinions on joining, and I mentioned @NCTM. Much to my surprise, they read the tweet and responded with a discount code for new members! I was happy to see that they were interested in new members, and excitedly took them up on their offer. Can’t wait to read their monthly journal, Teaching Children Mathematics, for some new instructional ideas.
