Error Analysis Response
Any Grade Level
Big Idea
Copy a problem (can use anonymous student examples!) and have the students find the error and explain how to correct the error.
When to Use
When students are stuggling with errors in Math
Directions
1. Give a formative assessment
2. Copy problems with student errors into the gray box
3. Have students fill out during a center or class activity
Sample debrief:
- Collect a sample of student work for each type of problem (e.g., single-digit addition; two-digit multiplication with regrouping), with at least three to five items for each problem type.
- Have the student verbalize or think aloud as s/he solves the problems without providing any type of cues or prompting.
- Record all student responses in written and verbal format.
- Analyze the responses and look for patterns among common problem types.
- Look for examples of "exceptions" to an apparent pattern (accurate "exceptions" could signal that the student does not fully understand the procedure or concept).
- Describe the patterns observed in simple language and the possible reasons for the student’s problems (e.g., if a student did not regroup double-digit addition problems, it could be a sign that the student does not understand the concept of place value).
- Interview the student by asking him/her to explain how s/he solved the problem to confirm suspected error patterns.
Common Challenges for Students to Look For
Lack of knowledge. Students’ lack of knowledge could be a major reason why they cannot solve certain problems consistently.
There are three types of errors: procedural, factual, and conceptual
Poor attention and carelessness
