Reflect on mistakes
The idea
An error can reveal a misunderstanding, a skipped step, or a reading mistake. Identify the cause before repeating more problems. Compare an incorrect method with a valid one and explain the difference. Keep a small record of patterns to guide future practice.
Worked example
If you added denominators when adding fractions, the issue is the meaning of equal-sized parts. Revisit a fraction model rather than only memorizing a correction.
Another application
If you confuse area and perimeter, compare surface-covering squares with boundary lengths. Solve one problem of each type and name the units; this tests the distinction rather than only a memorized formula.
A common misunderstanding
Repeating many problems with the same misunderstanding can reinforce the error. Diagnose why the method failed before adding more practice.
Try it yourself
Choose one error. Record the original attempt, the cause, a corrected solution, and a check you can use next time.
Check your understanding
Does fixing an answer always mean the misunderstanding is resolved?
Reveal the explained answer
No. Explain why the corrected method works and try a related problem.
