When your students do math word problems the hardest thing for them to do is to decide which operation to use. Teaching them to look for clue words is the key to solving word problems. These classroom charts will be a visual reminder for your students. They will help them to decide if they should add, subtract, multiply or divide. I have also included a one page chart that has all the operations that you can copy for each student to keep in their desks or take home to help with homework.
