Common student mistakes
Build distractors and reteach prompts around the errors students actually make on this standard.
- 1Rushing to an answer without showing intermediate steps or citing evidence — 6th-grade students who skip this stage often can't debug their own errors.
- 2Mis-identifying what the prompt is actually asking. On 6.RP.A.3, teachers see students latch onto surface keywords and pick the wrong operation.
- 3Applying a memorized procedure to a case where it doesn't fit — the classic ratios & proportional relationships trap when problems change form (e.g., If 3 apples cost $1.50, how much for 8?).
Teacher FAQ
