I’m interested in those little known workbooks, puzzles, websites, “games” that you and your kids were really impressed with, and that are maybe little known or really niche. We have something of a routine, in the summer and on weekend days, with the kids doing some daily math (Beast Academy for younger, Art of Problem Solving for the oldest), piano practice, and then a few other things before they are turned loose.
One of my goals this summer is to improve everyone’s penmanship for practical reasons, but had real trouble finding detailed or specific recommendations; got some cheap workbooks and we’ll see how that goes. But came across some mechanical puzzles, got one of those, and began to wonder if there were other unusual, quirky, educational materials out there that you wouldn’t think to ask about.
