Description: Subtaction across zero can be tricky. This will help your students by showing them where they made the mistake. Don't let them spend hours doing it wrong. Self Checking BoomCards are so much better. Let them practice using a FASTPIN and then they can sign in for a test grade. Self Grading is awesome for busy teachers.
