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)

1. 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

1.  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

1. 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

1. 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

1. 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 .
