Not enough mashed potatoes

Sour Cream Mashed Potatoes; Ina GartenUsing his famous mashed potato recipe, Brian has asked students

  • to change decimals to fractions,
  • to calculate ingredient measures for various-sized Thanksgiving gatherings,
  • to explain their thinking in calculating these figures
  • and to judge how many servings could be created from 7 ½ pounds of potatoes.


Act One:  Take a look at the pic. What questions come to mind?
Just before Thanksgiving there is an annual demonstration at the Winter Palace in the World Financial Center of New York City.   Canstruction is a celebration of design, of engineering, and of donating time, talent and food to the hungry. At the end of the exhibit all the amazing creations are dismantled and thousands of cans of food are given to hungry people via soup kitchens, food banks, shelters and senior homes.  Canstruction, Inc now has events in over 200 cities worldwide.

Here is a picture of an exhibit called "Downside Up" which was the winning exhibit from Canstruction, 2010, in New York City.

Act Two:  How many cans does it take to build this structure?  What information do you need to determine this?  How did you determine your solution? What else did you notice that is mathematical?

Egad!   There must be a million ways to craft one of these burger

How many ways do you think that there are?

Act I - Study the menu image on the right and consider what sort of burger you would like and how many ways you could choose your ingredients.

For toppings, you are allowed none, one, or any number of them. But for the bun, you can only choose one.

Act II - Look for a pattern in calculating how many ways both for when you could have only one and when you could have any number of sauces, toppings, yummy, etc.

Veterans Day

On Veterans Day we honor the men and women that have served in the Armed Forces of the United States.  As of the the 2010 Census, there are 18.8 million living veterans. We found these maps that show where veterans live in the U.S.

What do you notice and what do you wonder when seeing these maps?
