The concept of subtraction 3 - 4 yrs

I once heard of a father who taught his daughter about subtraction starting with the concept of “difference”. And moved attention form generic difference to the number. This way of teaching gets home the point of subtraction as much as standard ways

    Khan Academy video

    Finally the video from Khan Academy. But without the earlier steps these videos may not be as useful. It would also help to look at the addition videos of KhanAcademy
