This is a double digit addition and subtraction around the room activity. The word problems are mixed, some are solving, while some are estimating. This requires the students to read the problems carefully. I integrated them with Science and Social Studies for Virginia SOLS (word problems using terms from Native American unit, Habitats, and Regions of VA/fossils).
I printed off on neon paper and taped around the room. I also gave students a random card, and they created an EduCreations teaching how to solve.
