Look at these calculations.

372-91=

627+54=

Create your own word problem for these calculations.

1. #### Musa B.

I’m doing mine in the homework book

2. #### Halimah K.

Bronze:
1) 6 is the odd one out as it is the only even number.
2) 10 is the odd one out as 12,24,36 are the multiples of 12 and 10 isn’t.

Silver:
1) The whole intestine is 850cm long. The difference between the large intestine and the small intestine is 550cm long. 700+150=850, 700-150=550
2) There are 412 bones in 2 adult skeletons as 206×2 = 412.

Gold:
There can be 5 tripods and 4 bipods as 5×3 = 15 and 4×2 = 8, 15+8=23.
There can also be 10 bipods and 1 tripod as 2×10=20, 1×3=3, 20+3 is 23.

3. #### Jebrin Y.

Bronze:
1/ 15,6,3,17.17 is odd because 6,3,15 is in the 3 times table and 17 because is not in the three times table.
2/ 24,36,12,10. 10 is odd because it is the only one not in the 12 times tables.

Sliver:
Q1.)The whole intestine is 850cm long. The difference between the two intestines is 550cm long as 700-150 is equal 550cm.
Q2.)There are 412 bones in two adult bones. This is because 206 multiplied by 2 is 412.

Gold:
Q1.)10 bipods and 1 tripod.
5 tripods and 4 bipods.

Platinum:
Q1.)Sally had 372 toys. Sally gave away 91 toys. How many does she have left?

John had 627 cakes. His friend Thomas gives him 54 cakes. How many cakes does John now have?

4. #### Carter D.

Bronze
1. 17 is the odd one out because its not in the three times table
2.10 is the odd one out because its not in the 12 times tables.
Silver
1. 150+700=850 The difference between them is 550. i work this out by taking away 150 from 700.
2.412. I doubled it.

5. #### Hamza M.

150+700=850 because if we know that 7+1=8 then we also know 700+100=800

Bronze
1. 17 because it is not in the 3 times table
2.10 because it is not in the 3 times table
Silver
1. 850 because 700+100 equals 800 +50 =850
2.412 because 200 equals 400 and double 6 will equal 12

7. #### Hamza M.

Bronze#
1. 17 is the odd one out because its not in the 3 times table.
2. 10 is the odd one out because its not in the 3 times table.

• #### Hamza M.

1, How long is the whole intestine ?
I added the 150cms and 700cms to get how long the whole intestine is 150+700=850cms .
What is the difference between the 2 ?
I took away the shortest measurement from the longest to get the difference between the two intestines 750-150=550.
2, How many bones are in 2 skeletons ?
The human body has 206 bones so you add 206+206 together to get the correct answer 206+206=412.
Gold.
How many Tripods were there?
There are 4 Tripods.
How many Bipods?
There are 3 Bipods.
