Key idea

Align equal units. Exchange ten of one unit for one of the next when adding, and rename larger units when subtracting. Check with the inverse operation.

Sample problems

  1. Estimate, then find 3,685 + 2,478 using aligned columns. Label any regrouped units and check by subtraction.
  2. Estimate, then find 27,408 + 56,795 using aligned columns. Label any regrouped units and check by subtraction.
  3. Estimate, then find 6,002 − 2,785 using aligned columns. Show any exchanges, including across zeros. Check by addition.
  4. Estimate, then find 40,506 − 18,729 using aligned columns. Show any exchanges, including across zeros. Check by addition.

Common mistakes to watch for

  • A student adds 8 tens and 7 tens but forgets the ten exchanged from the ones column.
  • Check the place-value units and explain your reasoning.

The answer key explains each one, so you can tell what a wrong answer means.

How to use this set

  1. Teach with the slides (about 15 minutes): a warm-up, the big ideas, a “spot the slip” challenge, Mr DJ’s worked example, and a pick-your-pepper round on whiteboards. Or watch the video together.
  2. Practice with the worksheet. Everyone does Mild and Medium, then climbs to Spicy and Extra Spicy.
  3. Check understanding with the exit ticket, and send the homework home.
  4. Mark with the answer key — each answer shows the steps and the most likely mistake. The slides’ teacher notes are in the key too.
