what you did on the first one is good...this is how you should do the rest of them.
2.) 36 ÷ x = 6
(first box) 36 - x - x - x - x - x - x
(second box) this is going to be a tape with 6 groupings of 6 pieces
(third box) x = 6
the object is for you to fully understand that the x = 6 can be used in the second box in place of the x to give the same answer as 6...
36 - 6 - 6 - 6 - 6 - 6 - 6 = 6
all division is meant to be is a quick way of subtracting.....
keep going..you are doing well.
