Instructions

Work with a partner. Read through the problem.

Devise a plan to solve your problem and put the plan into action.

Prepare a short oral presentation to explain to your class how yousolved your chosen problem. Your explanation must include

[1] Your original plan of how to solve the problem.

[2] A step by step guide of what you did to get your answer.

[3] Details of any changes to your original plan and why thosechanges were made.

[4] A detailed explanation of all your working out.

Our Chosen Problem

Paste the problem you have chosen here:

Problem 2

Meredith is in training for the 2012 Olympics. She should swimat least 1,000,000 meters during 2009. How many laps of the pool

will she need to swim in order to swim 1,000,000 meters? How

many laps should she swim each day?


4/23

Our Plan1. To calculate laps she swims in a day.

2. Then after we times it by how many days in a year.

Which is 2,740 x 365=


5/23

Working out the answerFirst you divide 1,000,000 by 25 (this is the length of the pool) which

makes 40,000.

Then you divide 40,000 by 365 (days in a year which makes 110)

110 laps for 364 days and for one day she swims 104 laps.


6/23

Our Solution!So the answer would be 110 laps everyday and for just one day she

swims 104 laps. And there is the answer. 110 laps for 364 days and 104

laps for 1 day


7/23

How did we work it out?We worked it out by first starting with 1,000,000.

Then we divided by 25 (the length of the pool). The answer

was 40,000.

Then we divided 40,000 by 365 (the days in a year) and we got109. (we rounded it up to 110)

Then we calculated that she has to swim 110 meters for 364

days and for 1 day she has to swim 104 meters.

This is not the accurate answer but it is the approximate

answer. In all I think we did a pretty good job even though we

did not get the exact answer.

RE FL EC T Comment

Did I know enough

about 1,000,000 to

solve this problem?

FL We were kind of organized.

Did understanding how

a numbers place is

connected to its value

or size help me to solve

the problem?

T Yeah it kind of helped us.

What strategies did Iuse? Explain

(division,

multiplication,

subtraction, factors,

multiples, etc)

FL We used a lot of division to find our answer and a little bit ofmultiplication.

Problem Solving Strategies RE FL EC T Comment

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

FL Yeah I think that the plan I a lot different then the approximate answer.

2. Did we organise for different people to help

or complete different tasks?FL Yeah some people helped us a lot.

5. How did I use familiar landmarks I dont think we used any

(or groups of numbers) Tto solve the problem?

How did I check my estimations? RE By rounding to the nearest 10 to make it more simple

How did I check my calculations? RE By checking with other people that are good at math
