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 — 4th-grade students who skip this stage often can't debug their own errors.
  • 2Mis-identifying what the prompt is actually asking. On 4.NBT.B.4, 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 number & operations in base ten trap when problems change form (e.g., 3,486 + 2,759 = ?).
Teacher tip · Have students explain their math reasoning to a partner before writing it down — the talk exposes misconceptions faster than the paper does.
