One way to multiply a one-digit number by a number with

more than one digit is by using **partial products**.

**Step 1:** Write the second number under the first number so that the corresponding places are lined up.

**Step 2:** Expand the top number by place value.

**Step 3:** Multiply the bottom number by each number in the expansion.

| 443 | | 400 + 40 + 3 |

× | 8 | | |

3,200 | | 8 × 400 |

320 | | 8 × 40 |

24 | | 8 × 3 |

**Step 4:** Add the products.

| 443 | | |

× | 8 |

3,200 |

320 |

+ | 24 |

3,544 |

So, 443 × 8 = 3,544.

An **area model** can also be used to multiply using partial products.

**Step 1:** Set up the area model using place value.

**Step 2:** Multiply 8 by each number in the top row.

**Step 3:** Add the products.

3,200 + 320 + 24 = 3,544

So, 443 × 8 = 3,544.
