1) 15 because 15 is the odd One out
2) 10 because 10 is the odd one out
and 10 is in the 10 Times tables

Silver
700+150=850 so it’s 850cm long
700-150=550 so the difference is
550cm
Because I started with the longest
to the shortest

Gold
1) It can equal 23 because have 7 trpods and 1 hipod so it equal 23

Platinum
1) 372-91=281
2)627+54=68
234-11=223. 129+120=229
768-10=758. 123+121=244

Bronze:
1) 17 is the odd one out because 3, 6 and 15 are apart of the 3 times table.
2) 10 is the odd one out because it is not in the 3 times table and 12, 24, 36 all are.
Silver:
The whole intestine is 850cm long because 700cm + 150cm = 850cm and the difference is 550cm because 700cm – 150cm = 550cm.

1. Mrs A Patel

Well done DJ and Jatifor completing the maths challenge.

3. Welat M.

6 because all of the other ones are odd.
10 because it is a odd one and a even like the other ones
Silver
850 I know because 700 + 150 = 850
412 because 200+200 = 400 and 6+6= 12
Gold
G
First one is 10 bipods and 1 tripods because 2 times 10 = 20 and 1 times 3 = 23
2 finally 3 times 7 = 21 and + 2 = 23

4. Esa A.

1.It is 17 because it is not in the three timetables
2.It is 12 because it is not in the twelve timetables.
Silver
1.150+700=850
2.There are 412 bones in 2 skeletons
Gold
1.There are 4 Bipods and 5 Tripods, 4×2=8 and 5×3=15 so 8+15=23
2.There are 7 Bipods and 3 Tripods, 7×2=14 and 3×3=9 so 14+9=23
Platinum
372-91=281
627+54=681

Bronze:
1) 15, 6, 3, 17 The odd one is 17 because if you count in 3s you end up with 18 not 17.
2) 24,36, 12, 10 The odd one is 10 because it’s not included in the 3 times table.

Silver:
1) The intestine all together is 850. The difference is
150-700=550. I know this because you have to add first then you will no the difference because you just have to take away 150 from 700.
2) If there were 2 adult skeletons there would be 412 bones in total. I know this because 206+206=412 so 2 adult skeletons would have 412 bones in total.

Gold:
1) There could be 5 Tripods and 4 Bipods. There could be 7 Bipods and 3 Tripods.

Platinum:
372-91=281

627+54=681

My word problem.
If 372-91=281 would 91-372=281? 🤔
If you had £627 but the phone costed £681 would I need 54 more of 45 more? 🤔🌟👌🏻

I have done my working out in my home work book.
Bronze
The odd numbers are 27 and 10 because they are not in the 2 times table.

Silver
The length of the whole intestine is 850 cm I got this because I added
700 cm
+150 cm
= 850cm
Which gave me the answer 850 cm

700cm
– 150cm
= 650cm that is the difference between the 2 intestines.

Super maths work Eliza, well done!

The odd number out is 17 as its not in the 3 Times table.
The odd number out is 10 because 10 isn’t in the 10 Times table.
Sliver
150 + 700 =850
700 – 150 =550 difference
My English homework is in my homework book

1. Kitan O.

Also 206 +206 =412

2. Miss Jephcott

Well done Kitan ⭐️

9. Sumayyah A.

The odd number is 17 beacuse in the 3 x table the next number after 15 would be 18.

The odd number is 10 because in the 3 x table that number should be 9

150+700=850

700-150=550
To work out the diffecnce in legnth between the two intestines I took away 150 from 700 and the answer to work out the difference in length was 550

206+206=412

Tripods – 3
Bipods – 7

Tripods – 5
Bipods – 4

10. Sumaya O.

1. The odd one out is 17 because 17 is not in the three times tables.
2. It is 10 because 10 is not a multiple of three .
Silver
The answer is 850cm I know this because 150+700=850 and then I add the centermeters and I got 850cm I did it with formal written method .
The next answer is 412 because 206 +206=412 .

11. Faris B.

Silver
I added the large intestine and the small intestine together to get the total 700 + 150 = 850cm
To get the difference between the 2 intestines, I took the shortest away from the longest
700 – 150 = 550cm

1 skeleton has 206 bones so 2 skeletons will have 412 bones because 206 + 206 = 412

12. Havin A.

BRONZE
17 is the odd one out because if you count the 3 times table 17 is never there
2 10 is the odd one out because instead of 10 there is a 9 but never 10 in the three times table.
SilverThe large instine is 150+700 =850
The difference is if you put 700-150 =850 also
2A human body has 206 bones if there were two bodies in one that would =412 I now this because 206 +206 would equal 412
Gold
There are 3 bidpods and also 4
Tripods 3×4=12 there are now 2×3=6

Silver
150+700=850
700-150=550
I added 150 and 700 to get the answer and then for the second one I did minus it to get the answer.
206+206=412

One of the calculations you could have is 12+11=23 or 14+9=23

Good effort Alya ⭐️ Why don’t you give Silver a try?

19. Javishan R.

1. The odd one out is 17 because it’s not in the 3 time table.

2. 10 is the odd one out because the rest are in the 12 times table.

3. The whole intestine is 850cm long. The small intestine is 550cm longer than the long intestine.

4. A human body has 206 bones 2 human bodies are 412 bones I know this because 206+206=412

1.The odd numbers are 3,5,17.There re odd numbers because it can not be divided into pairs.
2.There are no odd numbers.
Silver
1A.It is 150cm+700cm=850cm.1B.The difference is 550cm.
2.It is 412 because I Know what 2+2=4 and I Know what 6+6=12.

17 is the odd number out because it is not in the 3 times table with 3 , 6 and 15.
10 is the odd number out because it is not in the 12 times table with 12 , 24 and 36.
Silver
150 + 700 = 850.
150 – 700 = 550 I know this because 100 – 700 = 600 so 50 – 600 = 550. 206 + 206 = 412 I know this because 200 + 200 = 400 ,
6 + 6 = 12 so 400 + 12 = 412.
Gold
There are 4 Tripods and there are 3 Bipods. 4 x 3 = 12 and 2 x 3 = 6

Tommy had 372 sweets then Oliver took 91 sweets away how many did Tommy have left?
372 – 91 = 281 Tommy has 281 sweets left.
Jenny had 627 apples in her farm , one of friend came and gave her 54 apples.
627 + 54 = 681 so now Jenny had 681 apples all together now.

17 is the odd one out beacuse you can not share them equallay in theree groups.
36 is the odd one out.
Silver:
206+206=412 Two skeltons are 412 bones.I know this beacuse 206+206=412.

There are 4 Tripods alltogether.
There are 2 Bipods alltogether.

My own problem solvings:
450-64=390
780+780=1560

17 is the odd one out because 15,6 and 3 are in the three times table
10 is the odd one out because the rest are in the 12 times table and every 2 added up

Silver
700 + 150 = 850 so it’s 850cm long.
700 – 150 = 550 so the difference is 550cm. To work the difference out I started with the longest and took away the shortest length.

Gold
It can equal 23 because there are 7tripods
And 1 bipod so it equals 23

Platinum
372 – 91 = 281
627+ 54 =681

17 because 17 isn’t in the 3 time tables
10 is the odd one out because 10 isn’t in the 3 times table

Bronze:
1. The odd one out is 17 because it’s not in the 3 time table.
2. The odd one out is 10 because it’s also not in the 3 time table.

Sliver:
1. 850 because 700 +150=850 because 700+100=800 and 800 + 50=850.
2. 412 because if you add the 200’s it equals 400 and add the 6’s it equals 12

Gold:
1. It can equal 23 because have 7 tripods and 1 bipod it equals 23.
2. To make 23 you can have 10 bipod and 1 tripods.

Platinum:
1. You can have 91 + 372.
