Here is a FREEBIE for you to use with your students. Great way to practice adding two-digit numbers and do some problem solving at the same time. There is one worksheet that is tied to the common core standards for 2nd, 3rd, and 4th grade. I would recommend that this would best be used with 3rd and 4th. This could be a bit challenging for 2nd grade. Great for use as a math center activity, or whole class activity. Answer key included. Please leave me feedback, your comments are very much appre
