Fill the piñata with individually wrapped candy or small, inexpensive toys or party favors. Hang the piñata outside from a tree branch, then let the children each take three turns hitting it with a sturdy stick or bat.
And here's the catch — the kids have to be blindfolded and twirl around a couple of times before they take a swing at it. Just make sure you clear a wide area to avoid injuries. If the piñata doesn't break after all children have had their respective turns, one or more adults can give it a whack or two. For the ultimate challenge, have someone move the piñata up and down while the kids try to hit it.
Team children with adults on a scavenger hunt through your guest-friendly neighborhood. Prepare lists in advance with Mexico-related items that need to be collected, such as a few tortilla chips, a jar of salsa, or an avocado.
Pass out a sheet of jumbled Spanish words and see who can unscramble the greatest number of words correctly.
Cut out pictures from magazines or copy electronic clip art onto a blank sheet of paper. Ask guests to print the Spanish word for each one (for example,"casa" for a picture of a house or "perro" for a picture of a dog).
