My book Prealgebra & Geometry: Math Games for Middle School is scheduled for release to regular bookstores in February, 2021. Because no publisher wants to send a new book into the world during such hectic, unsettled times as a big election, the winter holidays, or during inauguration season.
But preorder links are beginning to appear at several of the major online booksellers. And more stores will join them, as the information filters through their website systems.
The paperback will also be up for preorder, whenever the sites catch that update.
And remember: If you don’t favor a particular bookstore, you can buy the early-release ebook right now at my publisher’s webstore — and get a 10% discount if you order before 15 October.
