OECD Math Quiz - Sample Questions

http://www.oecd.org/pisa/test/

Explore PISA 2012 Mathematics Test Questions

The OECD's Programme for International Student Assessment (PISA) evaluates education systems worldwide by testing 15-year-olds in key subjects. The focus of PISA 2012 was mathematics. To understand more about the PISA 2012 mathematics test, click the link above to answer sample questions, explore the concepts being tested and learn what 15-year-olds students at different proficiency levels can do.
Canada was among 65 countries and economies participating in the assessment by the Organization for Economic Co-operation and Development, which takes place every three years. Findings of the OECD's Program for International Student Assessment — or PISA — from 2012 were released Tuesday.

More than 500,000 15-year-old students were tested on their knowledge and skills in three subject areas. The primary focus was on mathematics with a smaller proportion of students assessed in reading and science. Around 21,000 Canadians from about 900 schools across the country's 10 provinces took part. Canada's three territories elected not to participate.

Math POW Solution

Look at the above solution.  Is it the same as your response?  If it is different explain how it is different?  Do you think your answer is still correct even though it is different?  Which answer do you think is better? Explain why. Post your response.  (Remember to explain yourself clearly.)

David's Response -
Only answer a) is the same as my answer, b) and c) are not the same as mine.

On a) I had 2 adjacent squares and I only used 7 toothpicks. On b) I did not think of overlapping the squares to make 3 squares, Instead I just made two toothpicks double the size of the other three toothpicks like so, 2 lines are twice the size as so:

On c) I made three toothpicks double the size of the other 5 toothpicks to make 8 squares like so:

Chocolate and Child Labour

Fatima received a chocolate pumpkin as a gift from her friend on Hallowe'en. The chocolate cost $2.00 here in Ontario. The cocoa bean that was made into chocolate was harvested by a child in Africa. 

 For every dollar spent on chocolate here in Canada, 70 cents goes to the chocolate industry, 15 cents goes to marketing company, 10 cents goes to the packaging company and 5 cents goes to the worker in Africa.

 If $20.00 of chocolate is sold: How much profit does the chocolate company make? How much profit does the marketing company make? How much profit does the packaging company make? How many chocolate pumpkins must be sold for the child labourer to earn $20.00? 

  Show your work and find a way to display your results. Do you think the profits are shared fairly? Explain your answer.


What is your opinion about the above video clip? (Post your answers.)

It's The Great Pumpkin - Charlie Brown - Math POW - due Friday, Nov. 1st.

  Having made it safely back home from trick or treating, it's now time to check out your haul. You are to find the top 5 types of candy that you have collected. To aid you in this venture create a tally chart to record the tasty items. After having recorded tallies, it is now time to display them on a bar graph (We will do this in class - just bring in your tallies). Be sure to title your graph and label your axes. No need to worry, you don't have to record the rocks. Happy Hallowe'en!

Problem of the Week

Problem B

Double Trouble

Riley Waters has decided to join Facebook. A week after posting his profile,
he discovers he has two friends! After another week, his number of friends has
doubled to four. At the end of the third week, his total number of friends has
doubled yet again to 8.



a) If his number of friends continue to double each week, how many friends will Riley have at the end of 6 weeks? Create a T-chart to show your calculations.
b) Continue your chart to show how many friends
Riley would have after 10 weeks.

c) How long would it be until Riley has more than
15 000 friends?

d) There are about 34 million people in Canada. How
 long will it be until Riley is friends with at least
 that many people?
