Multiplying · Grade 6

In Grade 6 you learn: multiplying large numbers in problems.

Multiplying puts equal groups together. Once numbers get bigger than the times tables, we split them into parts and multiply each part: the area model, short multiplication and long multiplication.

Key facts

• Area model: 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.
• Long multiplication: multiply by the ones digit, then by the tens (put a 0 first), then add the rows.
• Estimate first by rounding each number; if your answer is far from the estimate, check your working.
