Have you introduced your 2nd graders to Tape Diagrams? If not, I highly recommend it! Tape Diagrams will get your students thinking and will allow you to include the rigor in your classroom that is required with the new standards. This resource contains four centers.
In this resource, students will read a word problem and will match it up with a correct representation of a Tape Diagram. Students then have the ability to solve it. Each center contains 12 word problem cards and 12 Tape Diagram cards and an accountability sheet. So, in all that is 48 word problems involving Addition and Subtraction within and beyond 100!
