Walmart and the truth in advertising.

A recent tv add from Walmart show a woman with a bag of groceries; the woman says:"if you spend $100 dollars per week on a bag of groceries like this then you could save $700 per year at Walmart on the same groceries. She then asks what would you do with the $700? The assignment today is to answer the following questions:


1. What would you do with the $700?


2. Why does the woman first say $100 dollars a week and then shift to $700 per year?


3. Use the calculator on the computer to find out how much of a savings $700 is per week.


4. What percent savings would this be?


5. Do you think this add is misleading in anyway?


6. Would you go to Walmart based on this add?

The World of M.C. Escher

M. C. Escher was one of the greatest graphic artists of all time. He was famous for drawings that trick the eye into seeing something that isn't really there. People describe his work as very mathematical. Today's challenge is to click on the link to the right and go to Escher's web site. Once there find the gallery of his most famous work. Pick one that you like the most. Post a comment that is at least one paragraph long that describes the work and why you think it is beautiful.

Game Theory

In our introduction to Probability we played two different games with cards. The branch of mathematics called Probability grew out of the desire of a few men to try and understand the ideas that explain the game they were playing at the time. Today we are going to try and understand the ideas behind several different types of games. Click on the link to the right and start to play. There is a question after you play each game.

A typical day in Hartford

We have been learning about three ways to find meaning in a set of data: the mean, median and mode. Each one has their uses; each one helps us find a pattern in a group of numbers. Mathematics is the science of finding patterns.

As human beings we try to make sense of the world around us by finding patterns and using those patterns to help us navigate in the world; traffic lights change from green to yellow then red.; we use this pattern to stay safe as a driver.

In the fall temperatures begin to drop; this pattern allows us to make decisions about clothing, food etc. Our activity today will further explore using mean, median and mode to find a pattern.







Problem 1.: A typical fall day in Hartford



During the last month the temperature has reached: 70, 55, 82, 77, 84, 65, 48. Find the mean median and mode and based on that information describe a typical October day in Hartford.





Problem 2: Use the internet to find the daily temperatures in Hartford during 7 days in July. Find the mean, median and mode and describe a typical day in Hartford in July.

The Power of Symbols

Today we looked at the power of symbols around us: some were on cars; some were on every day items; and X turned up on a tee shirt. Turns out the tee shirt was for the movie about Malcolm X, the black nationalist leader of the 1960's. He chose the last name X to represent the fact that he did not know his real name. As the descendant of slaves all he knew was his slave name. X was a symbol for a great unknown in his life. For more about Malcolm X please click the link to the right.

Communicating with Math

There are many ways to communicate with Mathematics. Over the past two weeks we have learned to find patterns in drawings; we have learned to find patterns in tables of numbers; and this week we are learning to change sentences into mathematical expressions. In each case we were learning to read the object in front of us. Learning to think mathematically is a way of looking at the world around us and finding a pattern. It is simply being awake and aware.
