This activity will have your students practice determining which sign, plus or minus, should go in the number sentences. There are a total of 56 cards. Some students could do all of them (full recording sheet included) or you could assign them cards #1-28 as a set and then cards #29-56 as a set. There are recording sheets for those 2 sets as well.
