Statistical Inquiry

WALT: Conduct a statistical inquiry.

Today we did a quick statistical inquiry. Toby and I asked the class how scared they are about Coronavirus. This is what we found out:


More people feel scared about the Coronavirus.

And eight people feel fine about it.

Times Table Practice:
3 x 3 = 9 5 x 5 = 25 8 x 7 = 56 12 x 10 = 120 4 x 6 = 24 5 x 7 = 35 2 x 4 = 8 3 x 8 = 24 9 x 8 = 72 4 x 7 = 28 9 x 7 = 63



Your sister gives you $125 to spend on lollies. If you spend $65 how much money would you have left over? $60
65 + 60 = 125



Zaeeda has bought her sister a new puppy. She has $500 in her bank account as she heads to the shops.




She first buys a dog bed for $60. How much money does she have left? 440
60 - 500 = 440





She then buys a bowl for $25. How much does she have left?$ 415
25 - 440 = 415





Then she buys 3 chew toys. Each toy costs $3.50. How much does she have left?$405.50c
$3 x $3.50 = 10.50c =$405.50c

Pt England school are buying new sports gear. There is $500 in the sports budget. 

They first purchase a basketball hoop for $50  How much money does is left? $450

500 - 50 = 450

They then buy a net for $25.  How much do they have left? $425

450 - 25 = 425

Then they buy three tennis balls. Each ball costs $3. How much do they have left? $422

425 - 3 = 422

Finally they buy a netball hoop which costs $100.  How much is left in the budget at the end? $322

422 - 100 = 322

Kahurangi wins some money and goes on a shopping spree.If he has 10.80 left in his bank account and he started with $525.80, how much did he spend? $515 

$515.00c + $10.80c = 525.80 

Zyla’s puppy is growing every month. He used to weigh 5.6 kg but he now weighs 6.3. How much weight has he put on? 7 Grams 5.6 kg + 4 grams= 6.0kg   6.0kg + 3 grams = 6.3 3+ 4= 7

factors and multiples

WALT: I am learning to identify factors and multiples

I had to find the factors of a range of numbers.




12 = 3, 6, 12, 1, 2, 4




24 = 12, 6, 3, 2, 8, 1,




36 = 6, 9, 4, 1, 36




50 = 10, 5, 50, 1, 25, 2




45 = 9, 5, 1, 45




20 = 10, 2, 5, 4, 1, 20




75 = 5, 15, 1, 75




100 = 10, 1, 100




150 = 10, 15, 1, 150





Then I listed the multiples of the following numbers, I went up to 10x




5 = 5, 10, 15, 20, 25, 30, 35, 40, 45, 50




6 = 6, 12, 18, 24, 30, 36, 42, 48, 54, 60




7 = 7, 14, 21, 28, 32, 42, 49, 56, 63, 70, 77, 84




8 = 8, 16, 24, 32, 40, 48, 56, 64, 72, 80, 88, 96




3 = 3, 6, 9, 12, 15, 18, 21, 24, 27, 30, 33, 36



15 = 15, 30, 45, 60, 75, 90, 105, 120, 135, 150, 165, 180, 195, 210, 225





The lowest common multiple (LCM) of 2 or more numbers is the smallest number that is a multiple of each of them. E.g. the lowest common multiple of 3 and 2 is 6. (they both also go into 30, but 6 is the smallest number they both go into).




I found the LCM of:




6 and 4 = 12




7 and 8 = 56




9 and 12 = 108




The highest common factor (HCF) is the highest number that can be divided exactly into each of two or more numbers.




For example, the common factors of 24 and 36 = 1, 2, 3, 4, 6, 8 and 12. So the highest common factor (H.C.F) of 24 and 36 = 12




I found he HCF of:




30 and 25 =5




14 and 21 = 7




56 and 49 =7




12 and 24 =12

AJ’s family are planning to build a treehouse in their garden. Some of Aj’s friends offer to help him to build it.

1. In order to start constructing the house,  AJ needs to get some wood from bunnings. His mum buys 45 planks of wood and his dad buys 132 planks of wood. How many do they have together? 177

 2. While building the house, AJ noticed that they were running out of nails so he went to buy some. They have 9 nails left at home. AJ  buys a pack of 145 nails and a pack of 50 nails. How many nails do they have now? 204 

3. To have a more stable treehouse, Jacob decided to tie the corner posts of the house to the tree itself. He used 24 cm of rope for the first post, 20cm on the second, 14cm on the third and 12cm on the fourth. How much rope was used? 70cm

4. The treehouse is almost done; all they need is to paint it. Paschal estimated that they will use 37L of white paint, 15L of green paint and 34L  of brown paint. How many litres of paint would they buy in total? 84L

5. After finishing the treehouse, AJs’ family made cookies for his friends to thank them for helping. If AJ ate 15 cookies, Jacob ate 10, Paschal ate 6  and Tisa only ate 5, how many cookies were eaten in total? 36

Show your working as you solve these problems:

145 + 235 = 280 

100 + 200 = 300

40 + 30 = 70 

5 + 5 = 10

134 + 127 = 261

1445 + 1564 = 3009

1235 + 5643 = 6878
