We start each class with a game called "caja mágica" (Magic box).
I think of a number, which is imaginarily placed in the magic box. The children start calling out numbers.
If the number is more (más) than the number in the magic box it will be placed above the box.
If the number is less (menos) it is placed below the box.

It is a fun game, that you can play at home and practice Spanish numbers at the same time!
