These are interesting word problems that students must really think about what the problem is asking in order to solve. There are 4 challenging word problems. Three of the word problems have blanks so you can use one of three different sets of numbers (provided in the back) to differentiate the problems to make them more challenging or easier for students. They are aligned to the Common Core State Standards. Although they are geared for 2nd grade, they could be used for 1st or 3rd graders. Feel free to break-up the problems (this would be a lot for students to do in one sitting).
