My second graders need a way to keep their subtraction skills with regrouping fresh in their minds, so I made up this activity for them. In this download you will receive a cover sheet to put on the outside of an envelope for file folder to hold all of the pieces. You will also get 12 snowflake cards with subtraction problems on them, and a worksheet for students to record their answers. In order to help the teacher check the student work, there is an answer sheet provided. You should be able to print, laminate, cut, make copies and go with this activity!
