Yes.. I do all those things too. I do teach the rules also. I stick to addition of pos and neg numbers until they have it mastered. (make sure to differentiate between the pos and neg signs and the plus and minus operation symbols.. I have them read the examples to me before even solving them.
When I get to subtraction .. I drill this .. KEEP CHANGE CHANGE
This means the first number you keep whatever it is.. Keep
Then Change the operation sign to a plus
Then change the integer sign to opposite of what it is
Then add the way they learned
