I predict that this problem will be about using the 4 operations.

READ:

I think of a number add 15 and then divide by 4. If the result is 5, what was the original number?

CLARIFY:

I had nothing to clarify in this question.

MY TOOL:

The tool I used to work this problem out was ‘Work Backwards’.

THE BIG QUESTION:

I think of a number add 15 and then divide by 4. If the result is 5, what was the original number?

SUMMARY:

All I had to do with this problem was work backwards by using the inverse operations. See, I multiplied 5 by 4 and then subtracted 15 to get 5. And (5+15) = 5

4

MY ANSWER:

My answer was 5.

PREDICT:

I predict that this problem is going to be about BODMAS.

READ:

I think of a number, divide it by 2 and then add 12. If the result is 20, what was the original number?

CLARIFY:

I had nothing to clarify in this question.

MY TOOL:

The tool I used to  work this problem out was ‘Write a Sum or Number Sentence’.

THE BIG QUESTION:

I divide a number by 2 and then add 12. If the result is 20, what was the original number?

SUMMARY:

First I subtracted 12 off 20, then I had 8 left. After that I doubled 8 which gave me 16, and 16 divided by 2 =8. Then I added 12 to 8 and gave me 20. I also learnt that all you have to do is work backwards by making the operations the opposites to themselves.

MY ANSWER:

My answer was 16.

READ:

The sum of two consecutive whole numbers is 97. What are the two numbers?

CLARIFY:

I had nothing to clarify in this problem.

MY TOOL:

The tool I used to work this problem out was ‘Guess, Check and Improve’.

THE BIG QUESTION:

What are the two consecutive numbers that add up to 97?

SUMMARY:

This problem was very simple and I did not have any trouble with working it out. I used estimation to estimate how much each number would have to be worth to reach 97. But before that I gathered the information that I already knew which was that 45 + 45 = 90. Then I just added 3 on to one of the numbers and 4 on to the other so I had 48 and 49.

MY ANSWER:

48+49=97

Nike IIIII    IIIII    IIIII 60%
Asics IIIII 20%

2.

Degrees and Percentage working out

Adidas Nike Asics Total
5/25 x 360°= 5/25 x 360/1= 1800/25= 72° 15/25 x 360°= 5/25 x 360/1= 5400/25= 216° 5/25 x 360°= 5/25 x 360/1= 1800/25= 72° 360°
