Gold

Platinum

Look at these calculations.

372-91=

627+54=

Create your own word problem for these calculations.

I’m doing mine in the homework book

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.

2)

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?

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.

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

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.

The answer is 412 because 200+200=400 and 6+6=12 so the answer is 412 Gold:There can be 7 tripods and 1 bipod or 10 bipod and 1 tripod Platinum:

Bronze

1.6 is the odd out one because It’s an even number.

2.10 is the odd out number because is not the 3 times table.

Silver

1.The Total whole intestine is 700+150=850

And the difference between the length is 700-150=550

2.two skeletons bones 206+206= 412

Gold

7 tripods were there and 1 bipods were there

And another answer 1tripods and 10 bipods were there

Platinum

372-91=281

627+54=681

Bronze

1.17 because it is not in the three times table

2.10 because it is not in the three times table

Silver

150+700=850 because 1+7=8,5+0=5 and 0+0=0 if you put it in order in will be 8 then 5 after that it will be 0 850 will be the the answer.The difference is 6 then you have to takeaway 5 and then you have to do nothing because it is already 0 100+600 equals 700 ,then you do 5-5=0 and then you do 0-0=0so it wold be 100+600-50-0 and the answer to the calculation will be 700.412

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.

Find 2 different answers.

4×3=12 2×3=6.
