Does anyone have any helpful hints or activities to help students be more aware of what type of math problem they are doing? I'm teaching a math intervention group and my kids have caught on to many of the procedures and tricks for addition, subtraction, and multiplication but are scoring poorly because they mix up the signs. I know they KNOW how, but on the "oh so mighty and important timed test" they bomb because they don't pay attention to the sign. Any helpful suggestions would be appreciated! Thanks!
