Multiplying · Year 5
In Year 5 you learn: 4-digit × 1-digit and 2-digit × 2-digit 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
- You can multiply in any order: 3 × 4 = 4 × 3.
- 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.
- Grid method: split both numbers into tens and ones, multiply each pair, then add.
- Short multiplication: multiply each digit by the single digit, starting with the ones, and carry.
