    1. 17 is the odd one out because it is not comes in the 3 times table . 15, 6
    and 3 comes in 3 times table. 3 times 5=15, 3 times 2= 6 , 3 times 1 =3.
    2. 10 is the odd one out because it does not comes in the 3 times table.
    Silver
    * The whole intestine is 850cm long. 700+ 150 = 850cm. The difference between the length of two intestine is 550 cm. 700 – 150 = 550 cm .
    * There are 412 bones in two skeletons. 206 + 206 = 412 bones.
    Gold
    *There were 5 Tripods. 3 X 5 = 15 .
    There were 4 Bipods . 2 x 4 = 8.
    15 + 8 = 23
    *There were 7 Tripods. 3 x 7 = 21
    * There were 1 Bipods. 2 x 1 = 2
    21+ 2 = 23

    17 because it’s not an equal number
    36 because it’s not equal and is not in the times table
    Silver
    150+700=850
    700-150=650
    The difference is that the longer bone is 850 and the smaller is 650
    I know this because I used my bigger number to add and my smaller to subtract
    Gold
    3×3=9
    So there are nine tripods
    2×3=6

    1. It’s 6 because out of the four they 6 was the only even number and the others were odd numbers.
    2. It’s 10 because10 isn’t in the 12 times table.

  15. Muhammed G.

    Bronze

    17 is the odd number out because 15 ,3 and 6 are all multiples of 3 and are all in the three times table however 17 is not so it is the odd one out.

    10 is the odd one out as 24 , 12 and 36 are all multiples of three times table and the 12 times table but 10 is not so it is the odd one out.

    Silver

    The length of the whole intestine is 850 cm I got this because I added 700 cm add 150 cm which gave me 850 cm I added these two numbers because they were the lengths of the two intestines to get the whole length I had to add up these two numbers .

    The difference between the small intestine and the large intestine is 550 cm I got this by subtracting 150 cm the length of the large intestine from 700 cm which is the length of the small intestine then I got 550 which is the difference between the small and large intestine.

    There are 412 in two skeletons . I know this because in one skeleton there is 206 bones so to work out the amount of bones into skeletons do you have to double 206 because that’s how many bones there are in one skeleton 206+206 = 412 therefore there are 412 bones in two skeletons .

    1) 3,15 and 17 is the odd one. Because 6 can be divided into 2.
    2) 10 is the odd out. Because it’s not in the 12 times table.

    silver.

    1) The whole intestine is 850 cm long.
    The difference between 150 and 700 is 550. Because 150 – 700 = 550 so 550 cm difference.

    2) 206 add 206 is 412 bones in two skeletons. 206+206= 412

  21. Amirah T.

    Bronze:
    1. 17 or 6 could be the odd one out. I think 17 because 17 isn’t in the 3 times table and the fact that the rest are. I also think 6 because it is the only even number there however, 15,17 and 3 are all odd numbers.
    2. 10 is the odd one out because 12, 24 and 36 are all in the 12 times table.

    Silver:
    1. The large intestine is 150 cm long and the small intestine is 700 cm long. How long is the whole intestine?

    The whole intestine is 850cm long. I know this because I added both numbers together. For example, I began by adding the units together 0 + 0, then I added up the tens 50 + 0 and finally, I added up the hundreds 700 + 100.

    What is the difference between the length of the two intestines?
    The difference between the two lengths of the intestines is 550. I know this because I subtracted both numbers and found the difference. For example, I began by subtracting the units 0 – 0, I then subtracted the hundreds 700 – 100 then I subtracted the tens 50 from the hundreds column to get my final answer, 600 – 50.

    2. There are 206 bones in an adult skeleton. How many bones are there in two skeletons? How do you know?

    There are 412 bones in two skeletons. I know this because I added both sums together. For example, I began by adding the units together, 6 + 6 = 12, then I carried the 10 over to the tens column. I then added the tens together, 10 + 0 = 10, and finally I added the hundreds together, 200 + 200 = 400.

    Gold:
    First Answer:
    There were 5 tripods and 4 bipods. I know this because I used the multiplication sum to find my answers. For example, 5 x 3 = 15 and 4 x 2 = 8. I then added the two answers together 15 + 8 = 23.
    Second Answer:
    There were 3 tripods and 7 bipods. I know this because I used the multiplication sum to find my answers. For example, 3 x 3 = 9 and 7 x 2 = 14. I then added the two answers together 14 + 9 = 23.
