Resist the allure of the TV, the iPad, the phone. Scratch that, because I bet you don't need much convincing to stay away from screens on the weekend. It's the kids that are feeling that pull more than anyone.
Full disclosure: Everyone at Boomdash loves TV and the wonderful, relaxing downtime and family time it brings. It's more the constant requests to turn it on or "watch another show" that we're trying to avoid. So offer up one or more of these activities that make much better use of their hands and brains than the remote control.
Plant a pizza garden Plant basil, tomatoes, peppers, oregano, parsley, and scallions in pots indoors or in a garden space, and come late summer, you’ll have everything you need for a killer pie.
Send them on a scavenger hunt It's basically the modern-day equivalent to a search for buried treasure (i.e., impossible to resist). If you want to make it brainy, throw some spelling and math into the clues.
Make slime (the new play dough) Playing with slime gives them that gooey texture they’ll love, but with virtually no cleanup. Plus it’s boredom-proof with all the variations, from the original Elmer's Glue recipe all the way to the cool magnetic version.
Get into origami Start with paper, end with a hat or a dog or a dragon. It works fine motor skills, but word to the wise: be careful not to choose anything too complicated, or it might end up crumpled on the floor.
