I've added critical thinking to our daily to do's, and I try to vary it every day for each kid, trying to stretch those brain muscles! Today DS and I came across this and I HAD to attempt it. I got stuck, so DS11 joined in while I helped DD with spelling...between DS and I we solved the puzzle only 2% can solve! (two heads are better than one right?)
Can you solve it? What do you do for logic or critical thinking?
