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.CC.C.6, 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 counting & cardinality trap when problems change form (e.g., Which has more — 4 cats or 7 cats?).
Teacher tip · Anchor K.CC.C.6 to a concrete manipulative or picture your students already know — abstract explanations don't land yet.
