In this fun freebie your students will be up and about, moving around your classroom (or school if you so choose!) solving subtraction problems that require them to borrow. Problems range from two digit - four digits numbers. There are 20 problem cards, a recording sheet, and answer key included.
I use this within my classroom and put the cards in a variety of hidden places (inside see through drawers, under a lampshade, taped to the window, etc) but have also used in throughout my whole school and as a hallway hunt.
I hope you enjoy!
