Try a sample

What is 46 × 15?

  1. 691
  2. 690
  3. 689
  4. 700
See the answer & why

690

Split 46 into 40 + 6: 40 × 15 = 600, and 6 × 15 = 90. Add them to get 690.

A little hint: Split one factor into tens and ones. Multiply both parts, then add.

A teaching tip

Show each partial product on an area model or place-value drawing. Both parts describe the original quantity.
