Yes, thanks for the video from me, too. We're going through this with my second grade son. He was pulling his hair out (ours too) when he had to do subtraction of two digit numbers using the book's method: a 10 by 10 matrix of numbers 1 - 100, and subtraction of, say, 57 - 30 involved finding 57 on the chart, and moving up 3 rows (each row = 10). I assume 57 - 31 involves moving two rows up and 1 extra jump to the left. I realize that addition and subtraction can be coceptualized as movement along lines, but, you don't need to fill your limited cognitive space with this idea every time you make change at the store. Besides, "mastering" by rote some of the math has the benefit of freeing cognitive space to deal with concepts (math or otherwise).
