Three levels

One skill, rising difficulty

Each sheet carries one level. The three are the same skill at rising difficulty, each named for what it practises.

Level 1: 2 digits, no regrouping
Multiply.
Level 2: 2 digits, with regrouping
Multiply. Regroup when you need to.
Level 3: 3 digits
Multiply. Regroup when you need to.

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: 2 digits, no regrouping

  1. Multiply the ones: 2 × 3 = 6. Write 6 under the ones.
  2. Multiply the tens: 3 × 3 = 9. Write 9 under the tens.
  3. So 32 × 3 = 96.

Level 2: 2 digits, with regrouping

  1. Ones: 7 × 4 = 28 ones. Write 8 in the ones and regroup 2 tens.
  2. Tens: 2 × 4 = 8 tens. Add the 2 regrouped tens: 8 + 2 = 10 tens.
  3. 10 tens is 1 hundred and 0 tens: write 0 in the tens, 1 in the hundreds. So 27 × 4 = 108.

Level 3: 3 digits

  1. Ones: 6 × 4 = 24 ones. Write 4 in the ones and regroup 2 tens.
  2. Tens: 3 × 4 = 12 tens, and 12 + 2 = 14 tens. Write 4 tens and regroup 1 hundred.
  3. Hundreds: 2 × 4 = 8, and 8 + 1 = 9 hundreds. So 236 × 4 = 944.
