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

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) 

 

  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 .

For this task, we were given a multiple status of Questions relating to a certain object/Person, The way I solved these Equations was using My Teachers Technique.

Polygons – Shapes!

For this task, We were learning about Polygon’s! what Polygon’s really mean is a shape that have multiple amounts of sides that are still equal and are made out of straight lines!.

This is One of the many Shapes I made with this app! ——> https://nrich.maths.org/dottyGrid/#/

It has 8 equal sides, 8 vertices (Corners), and is at a angel of 90!
