Teacher's field guide

What Students Need to Do: Students fluently add and subtract whole numbers through 1,000,000 with a standard algorithm. They align place values, regroup accurately, and check reasonableness.
What Mastery Looks Like: A student computes 483,726 + 159,845 and records every regrouping in the correct column. The student subtracts multi-digit numbers with zeros and verifies the result.
Common Misconceptions: Students may misalign digits, regroup across zeros incorrectly, or omit a carried value. They may accept an answer far from an estimate.
How to Assess It: Ask students to compute 604,308 minus 278,946 and 356,729 + 482,615 with a standard algorithm, then estimate to check one answer.

Lesson moves

Use place-value charts to rehearse regrouping, then connect each trade to the corresponding standard-algorithm notation.
Ask students how an estimate can reveal a misplaced digit in a multi-digit answer.
Play algorithm error hunt with misaligned digits, missed regrouping, and incorrect subtraction across zeros.
Update a large inventory or attendance total with multi-digit additions and subtractions.
