It is summer right now so I do not have any students.
I would teach this by drawing a diagram of the board showing 6 columns and 9 rows. I would then have them count out the 54 squares. I would then ask them, “if we need a total of 63 squares and we already have 54 squares how many more squares do we need?” They will then subtract 54 from 63 and come up with 9. I would then ask them how this information can be used to solve our problem.
