These 24 task cards include subtraction problems. Each card includes 2 student answers that your students need to "grade" and determine which answer is incorrect and explain why it is incorrect.
Addition problems include:
*2 digit, 3 digit, and 4 digit subtraction without regrouping
*2 digit, 3 digit and 4 digit subtraction with regrouping
*3 digit and 4 digit subtraction across 0s.
*Subtraction strategies: make a ten and make a hundred
*Estimate to find the difference: round to the nearest 10 and nearest 100
See if your students understand addition 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.
