This activity is aligned with the common core standard for 1st grade math (1.OA.6 fluently subtracting within 10).This packet includes subtraction flashcards to 10. I copy the flashcards on cardstock for the students to use for practice. After learning the facts the students are then given a one minute timed assessment on each of the fact families. I have included 0-10 fact assessment papers as well as 5 mixed fact assessments. Also included is a graph for the students to record and monitor their own progress. Thanks for looking!
