If I were teaching a youngster about addition, I would use tallying. In other words:
2 + 3 * * added to * * * * * * * * (count them) 5 Similarly for multiplication I would make rectangles and tally their contents If I was teaching someone with hopefully some familiarity with arithmetic I would not go so slow and carefully over the concepts as I would with a child, but perhaps something like this could be used for these animations?
