I'm a big fan of math based games. Especially when they can be used to hone basic skills. In this case, multiplication facts in the form of a "tic tac toe" style game called Number Hive that you can play against an AI or another online player. And I really like this description and endorsement by @MathGarden. It's pretty easy to get started and play so give it a shot.

I always like how @Howie_Hua breaks down why math "tricks" work. In this case, I don't know if I would call this a classic trick but I have done this sort of algebraic break down for similar problems with my students.

When you're introducing the idea of an ordered pair to students, it's often good to start with an image like this to get them thinking about quadrants in a less numerical way.
