Do you have a box of dominoes? Pulled it out lately? It might be time to build a dominoes course and let one of the kids knock it over.
Building a course without knocking it down is pretty challenging itself. Kids love to help build them, but of course aren’t always careful enough. Be ready to just laugh off the frustration if things fall down at the wrong time.
Make sure you aren’t building it someplace where someone is going to knock a domino over just accidentally, and that the surface is pretty stable. Accidents happen but you probably want to minimize the frustration when you’re trying to just have fun.
Get creative in your building process. You can make the dominoes course go over steps, drop from a height onto a lower track, and of course go all over the place.
