Want a new and improved way to help your students demonstrate their understanding of subtraction using the standard algorithm? Tired of the same old worksheets?

Error analysis problems are a great way to check your students' understanding of a concept. Instead of just solving the same problems again and again on a worksheet, they have to use their critical thinking skills to determine where, if anywhere, the example student(s) went wrong. This forces them to think outside of the box and develop a deeper understanding of the WHY behind the procedures and processes.

**Note: This product is part of a larger BUNDLE with 6 other skills. Click to SAVE $$!!**

This download includes five error analysis problems that practice addition. All problems will require regrouping. Three of the problems specifically use the standard algorithm of subtraction in the student work, and the other two could be solved using any method.

These tasks perfectly align with 4th grade Common Core standard: 4.NBT.4: Fluently add and subtract multi-digit whole numbers using the standard algorithm. They would also be great to use in a third grade classroom for acceleration or a fifth grade classroom for remediation.


These tasks would be great to use during guided math centers, whole-group centers, or independent practice.
