Math used to be taught with more drill style. Now with common core every single problem is an epic quest of 10 frames and double pluses. It seems so ridiculous. I'd rather them crush a worksheet of 20 problems that practices a single skill then 2 problems that try to include everything from reading to drawing just for a simple subtraction problem.
The problem with these 20 problems of basically the same identical challenge is that it's actually less effective than intermixing of different kind of problems, at least according to learning science.
You and I may prefer 20 problems that practice straight subtraction, but that's not what the science says is actually the most effective learning strategy.
You want different kind of problems in a problem set. It shouldn't be straight subtraction, but also additions, word problems, and so forth. This creates a level of desirable difficulty, which embeds knowledge more deeply than something that is very easy to do by rote.
