Please complete these on paper as many will need diagrams to complete your work.
Bronze:
How do you know?
Draw a diagram to show this.
Silver
What is a prime number? Create a checklist to help someone work out if their number is prime.
Gold
Use the same method to show all the factors for 24 and then 36.
Platinum
How did you solve it? Define a prime number and a square number.
List all the square numbers up to 100.
BRONZE:
800 X 10 = 800
SILVER
She has missed
Max has missed 28 and 17
GOLD:
Factors of 12 are 1,2,3,4,6 and 12 and the factors of 24 are 1,2,3,4,6,8 and 12 and factors of 36 are 1,2,3,4,6,12,18 and 36
Bronze
The answer is 8000 because 10X800=8000
Silver
The prime numbers that Max has missed are 1 and 9
Bronze:
800 x 10 = 8000
Silver :
He missed Prime numbers 17 and 29.
Gold:
12- 1,2,3,6,12
Platinum:
11-7= 4
BRONZE:
Alex runs 800 meters
Whitney runs 10X further
800X10=8000
10X times further so you take away 800 so the final answer is:
7200
SILVER:
the prime numbers are
2,3,5,7,11,13,17,19,23,29
so the two missing numbers are 17 and 29
GOLD:
factors of 12
1 x 12 = 12.
2 x 6 = 12.
3 x 4 = 12.
4 x 3 = 12.
PLATINUM:
11-7=4
Bronze
If Alex ran 800 meters and Whitney runs 10 times more than Alex she has ran 8000 ,I know this by 800 × 10 which equals 8000 ,whenever you times you will always move the digits one place to the left.This means that Whitney has ran 7200 meters more than Alex and I know this by adding 800 and 7200 together which will equal 8000.
Silver:
The missing prime numbers Max missed are,17 and 29
Gold:
This is another way to make arrays for 12 — — — — This example shows 4 × 3 or 3 × 4 – 12
Factors of 12 are:
1,12,2,6,3,4 – 1 × 12 , 2 × 6 , 3 × 4
Factors of 24 are:
1,24,2,12,3,8,4,6 – 1 × 24 , 2 × 12 , 3 × 8 , 4 × 6
Factors of 36 are:
1,36,2,18,3,12,4,9,6,
Platinum:
11 – 7 = 4 which is a squared number .
Squared up to 100 are:
1
4
9
16
25
36
49
64
81
100
Bronze:
8000 I know this because 800X10=8000
BRONZE
8000
because I know that 800×10=8000.
———————————————————-
SILVER
The numbers that Max are missing are 17&27. I know this because they are a prime number
———————————————————-
GOLD
Factors of 12:
1,2,3,4,6&36 because you can divide any of those numbers.
———————————————————-
Factors of 24:
1,2,3,4,6,8&12
EXAMPLE:
24 divide by 2=12
———————————————————-
FACTORS of 36:
1,2,3,4,6,6,12,18& 36
EXAMPLE:
36 divide by 2=18
Bronze
Whitney ran 8000 meters however Whitney also ran 7200 more then Alex I can prove this by using my time table knowledge and 800 x 10=8000 I know this because you just have to move the digits 1 forward if we were dividing out answer would of been 800.
Silver
A prime number is a number that the only factors are 1 and itself an example is 7. 7’s factors are 1 and 7 which makes it a prime number and 18 is not a prime number which we call a Non-prime number you can do 2 x 9 which equals 18. But the answer for this is 17 and 29 it can’t be 28 because 13 x 2=28 and it can’t be 16 because 4 x 4=16 it can’t be 30 because 10 x 3=30 and it can’t be 18 because like I showed 2 x9=18
Gold
Here is another example of an array which shows 12(4 lots of 3 also known as 4 x 3=12)
. . . .
. . . .
. . . .
Above shows 4 x 3 or you can say 3 x 4 which they both equal 12
Factors of 12 are: 1,12,2,3,4 and 6
1 x12=12
2×6=12
3×4=12
Factors of 24 are: 1,24,2,3,4,6,8 and 12!
1 x24=24
2 x12=24
3 x 8=24
4 x 6=24
Factors of 36 are: 1,36,2,3,4,6,9 12 and 18!
1 x36=36
2×18=36
3×12=36
4 x 9=36
6 x 6=36
There is no 5’s in this because all of the numbers in the 5 times table either end in a 5 or a 0 for example 5 x 10=50 or even 5 x 5=25
Platinum
This can either be 11 – 7=4 or it can be 13 – 4 =9(11 and 13 are prime number and 4 and 9 is a square number)
Sorry that this came in late!
The question is eleven – seven= four
I found out that ten – one -hundred then subtracting seven from a prime number to make a one – digit number then I crossed off all of the answers with two -digit numbers the only prime numbers left were thirteen and eleven. I then did thirteen– seven= six, but six wasn’t a square number. Then, I did eleven – seven= four then I got my answer
the square numbers from one – One-hundred are
One
Four
Nine
Sixteen
Twenty-five
Thirty-six
Fourty-nine
Sixty-four
Eighth-one
One-hundred
Bronze
1) Alex ran 7200m more . I know this because 800×1000=8000-800=7200.
Silver
2) The prime numbers are
2,3,5,7,11,13,17,19,23,29 . A prime number is a number that only can times by 1 and itself.
Gold
3)Factors of twelve are:
1×12 2×6 3×4 they all equal twelve.
Factors of Twenty-four are:
1×24 12×2 3×8 4×6 these are all equal to Twenty-four
Factors of Thirty-six are:
1×36,3×12 2×18 4×9 they are all equal to Thirty-six
This is the other part

11 – 7 = 4. 11 is a prime number and when you take 7 away from it, it equals 4 which is a square number.
I completed and will hand in
Bronze
Whitney runs 7200 meters further than Alex. I know this because 800X10=8000 and 8000-800=7200
Silver
3,5,7,11,13,17,19,23,29and31 are all prime numbers
So max missed 17 and 29
Bronze
Alex = 800m
Whitney = 800 x 10 = 8000
Silver
The prime numbers that are missing are 17 and 29.
Platinum :
1) The question is 11 – 7 = 4.
2) I found this out by writing the prime numbers from 10 – 100 and then subtracting 7 from the prime numbers to make a 1 – digit number. Then I crossed of all
Sorry, I accidentally posted my comment too early.

The anzer are 11-7=4,13-4=9 because 4,9 are square numbers and 11,13 are prime numbers .
Bronze:
Whitney ran 7200 metres more than Alex because 800×10=8000 and 8000-800=7200
Silver:
Max missed 17 and 29 not 27 because 3x3x3=27 and 3×9=27

8000 because 10×800=8000
Silver
The prime numbers he missed was 27
Bronze:
Bronze:
It could be 900 because if 100 + 800 = 900
Then the answer is 900.
Silver:
17 and 29 because you can’t have any factors to times by to get that number (what I’m saying is ,the only factors are 1 and itself).
Gold:
The factors of 12 are :
1,12,2,3,4 and 6.

I think max Miss out 15 and 27.
I will hand my work to the teacher.

I know this because 800 X 10 = 8000
Silver
27 and 17
Gold
factors of 12
1,2,3,4,36 and 6 because you can divide twelve by any of those numbers.
factors of 24
1,2,3,4,6,8, and 12 because you can divide these numbers by 24 like 2 divided by 12 = 24.
factors of 36
1, 2, 3, 4, 6, 9, 12, 18, and 36!!
Example:
12 divided by 3 = 36
Platinum
13-7=6
11-7=4
This is all I could do because if you use a prime number and minus it by seven and it becomes something for example 13-7=6 there is entirely no way of how to put a prime number then minus it into a squared number.
Sorry you actually can because 2 squared equals 4.
