This bundle includes 3 sets of Find the Mistake: Addition and Subtraction cards. Each set includes 24 task cards. That's a total of 72 task cards! Each card includes 2 student answers that your students need to use error analysis to "grade" and determine which answer is incorrect and explain why it is incorrect. Numbers are included through the thousands place.
See if your students understand addition and subtraction well enough to look for others' mistakes. After getting into the habitat of looking for mistakes, hopefully students will learn the importance of double checking their own work.
