The new blog carnival is posted and full of fun:
Next month, the carnival is coming back home to Let’s Play Math! — and in fact, I’ve already started collecting articles for it. If you would like to contribute, you can use this handy submission form. If you’d like to host a future edition (July or later), let me know.
Claim your two free learning guide booklets, and be one of the first to hear about new books, revisions, and sales or other promotions.
