My girls LOVED playing with dominoes– way before they know how to play the real game as it’s meant to be played. Matching them up, building labyrinths with the matches, the really fun domino snake that gets knocked over with 1 ‘flick’ of the fingers. It’s math, it’s spatial, and they’re fun.
Dig them out of the attic or go buy a set for your kids and you’ll have an engaging activity for them when they need one.
Here’s a shout out to handsonaswegrow.com for the reminder about domino fun.
