Which problems can I make?

2, 3 or 4 digits times 1 digit, and 2 or 3 digits times 2 digits.

Is there room for the working?

Yes. Problems with a two-digit bottom number have two lines for the partial products, then a line for the total.

The final product, and for two-digit multipliers both partial products, so you can see where a mistake happened.

Multiplying by 0 or 1 skips the real work, so every digit of the bottom number is 2 to 9.

Multi-digit multiplication from 47 × 6 to 416 × 35, with room for the working and answer keys that show it.

$Long multiplication preview$

2 digits by 1. Multiply the ones, carry, then multiply the tens.
3 and 4 digits by 1. The same steps across more columns.
2 digits by 2. Two partial products, one for the ones and one for the tens, then add them.
3 digits by 2. Bigger numbers, the same method.

Long multiplication goes smoothly once the facts are automatic. If they are not yet, practice with the times tables worksheets alongside.
