Mental Math and Estimation Review Template

Mental math and estimation review template for tracking prompts, methods, arithmetic misses, assumption misses, calibration, and next drills.

Candidates who need a repeatable review process after drills and mocks.

Record the prompt and target

Write the exact question, requested unit, and time period. Many review discoveries start with realizing the target was unclear.

Separate error types

Tag misses as arithmetic, assumption, unit, decomposition, calibration, or communication. Different misses need different repair drills.

Concrete fields

Use fields for prompt, target unit, method, assumptions, arithmetic miss, sanity check, final range, feedback, and next drill.

Close with one drill

Every review should produce one specific next action. If the miss was unit conversion, the drill should target unit conversion rather than general practice.

Common mistakes

Candidates often write long notes but no repair action. A useful template turns feedback into the next practice block, with one retestable drill.

Practice the pattern

Use the LeetQuidity curriculum and calibration to turn this topic into a focused practice plan.
