Worked example

How the sheet explains it

The helper printed at the top of each sheet: one solved example and the steps a student follows, before the first question. Every number sentence in it is proven by the same checker as the answer key.

Level 1: No regrouping

  1. Line up the places. Add the ones: 2 + 6 = 8.
  2. Add the tens: 5 + 1 = 6. Add the hundreds: 3 + 4 = 7.
  3. Add the thousands: 4 + 2 = 6. So 4352 + 2416 = 6768.

Level 2: Regrouping once

  1. Line up the places. Ones: 5 + 2 = 7. Tens: 3 + 4 = 7.
  2. Hundreds: 7 + 8 = 15. Write 5 and regroup 10 hundreds as 1 thousand.
  3. Thousands, with the regrouped thousand: 2 + 1 + 1 = 4. So 2735 + 1842 = 4577.
  4. Regroup ones or tens the same way: 10 ones make 1 ten, and 10 tens make 1 hundred.

Level 3: Regrouping more than once

  1. Ones: 7 + 9 = 16. Write 6 and regroup 1 ten.
  2. Tens: 8 + 5 + 1 = 14. Write 4 and regroup 1 hundred.
  3. Hundreds: 6 + 9 + 1 = 16. Write 6 and regroup 1 thousand.
  4. Thousands: 4 + 2 + 1 = 7. So 4687 + 2959 = 7646.
