Common student mistakes
Build distractors and reteach prompts around the errors students actually make on this standard.
- 1Rushing to an answer without showing the work with pictures or manipulatives — kindergarten students who skip this stage often can't debug their own errors.
- 2Mis-identifying what the prompt is actually asking. On K.MD.A.1, 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 measurement & data trap when problems change form (e.g., Is the pencil longer or shorter than the crayon?).
