NCTM Twitter Chats take place on the 2nd, 3rd, and 4th Wednesday evenings of most months, with a week of the month dedicated for topics from each of our grade-band focused school journals.
Chat participants discuss a recent article or blog post from the corresponding journal. The chats begin at 9:00 p.m. ET and last about an hour, centering around six open-ended questions every 10 minutes.

blog posts from various journal authors each month. Regular
webinars from book authors themselves will also take place to provide additional opportunities to collaborate and learn.
