I created this set to differentiate the subtraction unit in my class this year. There are 3 sheets in this pack--subtracting 2-digit minus 2-digit, subtracting 3-digit minus 2-digit, and subtracting 3-digit minus 3-digit. There is workspace inside each shamrock for the students to solve the problems using any strategy they would like. This would be great for small groups, independent work, a math center, homework, or an assessment! Also, check out my Valentine addition and subtraction sheets, as well as multiplication and division, and my St. Patty's Day addition, multiplication and division packs!
