Split or Stack
Teams solve multi-digit multiplication one step at a time. Each problem, choose Split it (area model and partial products) or the standard algorithm, then check each other's work and call Challenge! on mistakes.
Try it free with your class: the demo runs right in your browser for 5 questions or 5 minutes, whichever comes first. No sign-up needed.
Or get every game, including all future games, with the All-Access Teacher License for $150.
