I teach in a 4th grade, self-contained, 12:1 class. My students are generally capable of the basic operations required in the 4th grade curriculum, but struggle with processing word problems. Most importantly, in choosing the correct operation(s) to use in order to solve.
This is a quick, addition and subtraction question sort. Print the sheets, then cut them up. The students should use the header cards to sort the questions into addition or subtraction problems. Once the sort is complete & correct, they may solve the problems, if you wish.
