This worksheet is a flexible solution to math worksheets in the 21st century classroom! I created this resource for use with Carole Fullerton's amazing addition and subtraction resource (FIND IT HERE: https://www.ecwid.com/store/mindfull/#!/Sums-and-Differences-for-Grades-1&2/p/55379465/category=14772493).
