This is a great way to have students work on their on problems but be able to help each other out without cheating. This includes a worksheet with 9 questions and an answer key.
Students do their own set of problems but the same numbers have the same answers, so both number 1's equal the same expression. Students can do their own problems and then check with their neighbor to see if they have the same answer if not then they can help each other figure out what they did wrong and teach them the correct way to do solve the problem without constantly asking you questions.
Look for more to come!
