A long time ago I taught my daughter, who was in grade 3, how to differentiate simple polynomial functions just to show that just knowing an algorithm doesn't mean you understand the math. So this totally resonates with me.

I like this post from @MrJohnRowe about focussing on when students "stall" when problem solving or when they don't even start. "We need to do a better job at helping students with “Problem Starting” and be less obsessed with “Problem Solving”. We undoubtedly need to do a better job at normalising not knowing".We were just talking about this at my school. The idea that sometimes when students can't see a way to start right away, it becomes debilitating.

I have always liked row games as a way to have a more interactive worksheet. The idea is that you have two columns of questions and you pair students up. Each student chooses a column and does all the questions in that column. They check their answers by seeing if they get the same value for their questions that are in the same row (even though they are different questions). They take some time and planning to create so it's always great when someone makes one (or some). Here are some that I've made.
