Multiplying · Year 6
In Year 6 you learn: long multiplication.
Multiplying puts equal groups together. Once numbers get bigger than the times tables, we split them into parts and multiply each part: the grid method, short multiplication and long multiplication.
Key facts
- To multiply by a multiple of 10, use a times table fact, then make it 10 times bigger: 6 × 4 = 24, so 6 × 40 = 240.
- Short multiplication: multiply each digit by the single digit, starting with the ones, and carry.
- Long multiplication: multiply by the ones digit, then by the tens (put a 0 first), then add the rows.
