Our Chosen Problem

Paste the problem you have chosen here:

Varakorn is in training for the 2012

Olympics. He should run at least

1,000,000 meters during the year

2009. How many laps of the ovalwill he need to run in order to run

1,000,000 meters? How many laps

should he run each day?


4/23

Our PlanWrite your plan of how you will solve the problem here:

Our plan was to go around the oval once and then divide 1,000,000 by the

length of the oval and then divide again by 361(356).

Why will you divide the number by 361?

Because there are 356 days in a normal year.

There are 365 days in a year!


5/23

Working out the answer

Show how have worked out your answer here.

Its 134m around the oval and divide 1,000,000by 134. It is about 7,462

and then well divide it by 365 and it is about 20


6/23

Our Solution!

Varakorn needs to run about 20 laps each day.

Checking: 20 X 365 (days) = (10X 365) X2 = 3650 X2 = 7,300

7,300 X 134 = 987,200

Welldone, this is a good estimate!

How did we work it out?Write a step by step guide of what you did to get your answer.

You may need more than one slide.

Include details of any changes to your original plan and why those

changes were made.

Our plan was to go around the oval once and then divide

1,000,000 into the length of the oval and then divide again

into 365.

RE FL EC T Comment

Did I know enough

about 1,000,000 to

solve this problem?

RE It took us only a few minutes to figure out the answer because

we knew a lot about 1,000,000.

Did understanding how

a numbers place is

connected to its value

or size help me to solve

the problem?

FL It was kind of confusing to do it because a million is a big number

and its confusing.

What strategies did Iuse? Explain

(division,

multiplication,

subtraction, factors,

multiples, etc)

RE I used quite a lot of strategies to figure it out.

Problem Solving Strategies RE FL EC T Comment

1. Did we create a good plan and change it whenneeded?

FL My plan didnt worked out well.

2. Did we organise for different people to help

or complete different tasks?

EC I did it by myself.

5. How did I use familiar landmarks (or groups of numbers)

to solve the problem? EC I did it by myself.

How did I check my estimations? RE I tried it again.

How did I check my calculations? EC I used only a calculator.

Our Chosen Problem

Choose a problem from the slides at the endof this presentation and paste it here:

Problem 1

We are recreating the juniorschool library. It needs to

house 1,000,000 books that

are on average about the same

with as an Oxford dictionary.

How many meters of shelving

will we need?


13/23

Our PlanWrite your plan of how you will solve the problem here:

5 times 1000000 =5000000cm divided by 100=50000.

How did we work it out?Show how you have worked out your answer here.Write a step by step guide of what you did to get your answer.

You may need more than one slide.

Include details of any changes to your original plan and why those changes were made.

We measured the book by cm and multiplied by one million and then divided by 100and we got 50000.


15/23

Our Solution!

We need a 50000 meters to fit 1000000 books.
