Hey Gang,

I was given this strategy by a co-worker this year. LCO- take the problem -7 - (-10) I always have my students put the last negative number in (). Leave the first number -7 change the sign + and do the opposite for the next number. -7 + 10= 3. They have to write LCO on their papers and then rewrite the problem. If they practice it enough ....they will get it. Hope this helps.
