Multiplying and dividing · Year 3

In Year 3 you learn: equal groups, arrays and sharing; multiplying and dividing within 100; 2-digit × 1-digit multiplication.

Once numbers get bigger than the times tables, we multiply by splitting numbers into parts (short and long multiplication, or the grid method) and divide with short division. Division doesn't always come out exactly; what to do with a remainder depends on the question.

Key facts

  • Grid method: split both numbers into tens and ones, multiply each pair, then add.
