Example | 22 x 4 = | 88 | |

1 | 24 x 3 = | 20 x 3 = 60, 4 x 3 = 12, 60 + 12 = | 72 |

2 | 25 x 5 = | 20 x 5 = 100, 5 x 5 = 25, 100 + 25 = | 125 |

3 | 21 x 4 = | 20 x 4 = 80, 1 x 4 = 4 , 80 + 4 = 84 | 84 |

4 | 22 x 3 = | 20 x 3 = 60, 2 x 3 = 6 , 60 + 6 = 66 | 66 |

5 | 23 x 4 = | 20 x 4 = 80, 3 x 4 = 10, 80 + 10 = 90 | 90 |

6 | 19 x 4 = | 10 x 4 = 40, 9 x 4 = 36, 40 x 36 = 76 | 76 |

7 | 17 x 5 = | 10 x 5 = 50, 7 x 5 = 35, 50 + 35 = 85 | 85 |

8 | 27 x 4 = | 20 x 4 = 80, 7 x 4 = 28, 80 + 28 = 108 | 108 |

9 | 28 x 3 = | 20 x 3 = 60, 8 x 3 = 24, 60 + 24 = 84 | 84 |

10 | 21 x 5 = | 20 x 5 = 100, 1 x 5 = 5, 100 + 5 = 105 | 105 |

Answer the word problems below.

Write the multiplication equation and show your working.

Example: Paper Depot is sending out 8 trucks to deliver paper to customers today. Each truck is being loaded with 29 cases of paper. How many cases will be delivered today?

29 x 8 = 20 x 8 + 9 x 8 = 160 + 72 = 232 (using place value)

30 x 8 – 1 x 8 = 240 – 8 = 232 (using tidy numbers)

- The candy hearts container has 46 candy hearts in it. I have 8 containers,

how many candy hearts do I have?

46 x 8 = 00

40 x 8 = 320, 6 x 8 = 48 , 320 + 48 = 368

- I can type 49 words per minute. How many words would I type in 8 minutes?

49 x 8 = 00

40 x 8 = 320, 9 x 8 = 81, 320 + 81 = 401 Words

- I’m going to the circus in 9 days. How many hours before I go to the circus?

216, Each day is 24 hours a day and adding another 24 that is 48, if we were to do 24 Nine times the original answer would be 216.

24 x 9 = 180 , 4 x 9 = 36, 180 + 36 = 216

- The airplane sits 8 people across and it has 32 rows. How many people can fly on this airplane at once?

8 x 32 = 256

8 x 30 = 240 , 8 x 2 = 16, 240 + 16 = 256

- I play 30 minutes of hockey 4 days per week. How many minutes of hockey do I play each week?

120

30 x 4 = 120, 0 x 4 = 0, 120 + 0 =120 .
