Over the holidays, I was drawn into a game of “heads down, thumbs up” with my grandchildren. The game originated in the 1950s, but it’s still a great way to entertain a group of 4-to-8-year-olds. Players around a table lower their heads into their folded arms to shield their eyes and extend an arm into the middle of the table with the thumb up. Several other players walk around the table and push down the thumb of a player they’ve selected. At the command “heads up” the players around the table must guess who pushed down their thumb.
