Which deal costs less per millilitre?
A) 75c for 500 mL
B) $2 for 2 L
Answer:
B
What’s the BIG Question? :
Which is a better deal?
What Strategy Will I Use? :
Create a mathematical problem
Solving Procedure:
I knew I needed to multiply 75c four times. I doubled 75 and got 150 and then doubled that and that made 300, which makes $3 for two litres so the answer is B.

Which deal costs lees per litre?
A) $32 for 4L
B) $8.50 for 1L
Answer:
A
What’s the BIG Question? :
Which is a better deal?
What Strategy Will I Use? :
Create a mathematical sum
Solving Procedure:
I added 8.50 four times by doubling then doubling again and here is what I got was, in the first double I got $17 I doubled that and got $34. That makes the answer A because A costs lees per litre.

Which deal costs less per metre?
A) $1.50 for 15m
B) $5 for 45m
Answer:
A
What’s the BIG Question? :
Which is better value?
What Strategy Will I Use? :
Create a mathematical sum
Solving Procedure:
I added $1.50 until I got 45m and that was 3 times. 3 times $1.50 equals $4.50 for 45m. That makes the answer A because it cost less per metre.

Which deal costs less per gram?
A) $5 for 500g
B) $3 for 250g
Answer:
A
What’s the BIG Question? :
Which is better value?
What Strategy Will I Use? :
Create a sum
Solving Procedure:
I added B two times because it would then be five hundred grams and will be even to option A and I got six so the answer must be A because it cost less for the same amount

8x =56
Answer:
8x 7 =56
What’s the BIG Question? :
What number goes in the box?
What Strategy Will I Use? :
Create a mathematical problem
Solving Procedure:
I know eight times seven equals fifty-six so I put seven in the box and to check it I did eight times seven equals fifty-six.
Predict:
I predict it is about numbers and division
Read:
divide 5=9
Answer:
45 divide5=9
What’s the BIG Question? :
What number goes in the box?
What Strategy Will I Use? :
Work backwards
Solving Procedure:
I worked backwards because five and nine are there so I turn the division into multiplication and I multiplied five and nine to get forty-five and I just worked it out the normal way to confirm it.

I think of a number, multiply it by 4 and then divide by 3. If the result is 12, what was the original number?
Answer:
9
What’s the BIG Question? :
What is the original number?
What Strategy Will I Use? :
Create a mathematical question
Solving Procedure:
I just reversed what it did to the number so I multiplied twelve by three which gave me thirty-six then divided by four and got nine.

Answer:
7 9
+ 5 6
—————–
2 3
What’s the BIG Question?:
The big question is what are the numbers in them gaps?
What strategy will I use?:
Create a mathematical problem
Solving Procedure:
I start at the ones are and I see nine and a gap then a three what number is in the gap since three can only make nine by adding six so the first one is six. The tens area I see a gap a five and a two what I so is add two to five which is seven.

I think of a number, add 15 and then divide by 4. If the result is 5 what was the original number?
Answer:
5
What’s the BIG Question? :
What is the original number?
What Strategy Will I Use? :
Create a mathematical problem
Solving Procedure:
I just reversed the process which gave me five so what I did was I times five by four and then minus fifteen to get the answer five
