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

Gold

Platinum

Look at these calculations.

372-91=

627+54=

Create your own word problem for these calculations.

Bronze

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 itβs 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

Create your own number

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.

Well done DJ and Jatifor completing the maths challenge.

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

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? π€

If you had Β£627 but the phone costed Β£681 would I need 54 more of 45 more? π€πππ»

Super work Hadiya βοΈ

π

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!

Bronze

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

Also 206 +206 =412

Well done Kitan βοΈ

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

To get this number I added one adult skeleton to another.

Tripods – 3

Bipods – 7

Tripods – 5

Bipods – 4

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 .

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

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 3Γ4=12 there are now 2Γ3=6

Platinum

I have done my math homework.

Bronze

The odd number is 17 because it is not in the 3 times table.

The odd number is 10 because it is not in the 3 times table.

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

I added them together to get the answer.

Gold

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

Well done Eva βοΈ

Thank you!

I have even done it in my homework book.

I have done the maths challenge in my home work book

17 because 17 is not in the 3 time table

10 beause 10 is not in the 3 time table

Good effort Alya βοΈ Why donβt you give Silver a try?

1. The odd one out is 17 because itβs 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

5. To make 23 you can have 10 bipod and 1 tripods.

My Maths bronze, silver and gold work is in my homework book.

My English work is in my homework book.

Bronze

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.

Gold

There 10 Bipods=20 legs and 1 Tripods=3 legs.

Bronze

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

Platinum

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.

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 itβs 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
