A common struggle that I have seen with each group of students that I have taught is them being able to identify "signal words" in word problems.These flash cards were created to help students identify which "signal words" go with each operation. All you have to do is print them on cardstock and laminate! Print them double-sided for flash cards, or print them single-sided to use them as memory/concentration cards! Two in one! I also included some blank cards if you want to add some words of your own!
